Summer is here, and whether you’re planning a weekend wild camping trip in the Cairngorms, a long-distance trail run through the Peak District, or simply heading out for a full-day walk with the family, one thing is certain, the right kit makes all the difference.
At TacTree we stock the kind of gear that doesn’t let you down. Trusted by military personnel, outdoor professionals, and everyday adventurers alike, our range is built around performance, durability, and value. In this guide, we’re breaking down exactly what you need to pack for summer — from the base layer on your back to the boots on your feet.
Section 1: Clothing for the Elements
Summer weather in the UK is nothing if not unpredictable. One hour you’re baking in 25°C sunshine, the next you’re pulling on a layer as the wind picks up on an exposed ridge. Building a smart, layered clothing system means you’re always comfortable, whatever the day throws at you.
T-Shirts: The Foundation of Any Summer Kit
Your base layer is the most important piece of clothing you own. A poor-quality t-shirt will leave you chafed, sweaty, and uncomfortable within the first hour. A good one becomes almost invisible — you forget you’re wearing it.
We recommend opting for technical fabrics over cotton wherever possible. Cotton holds moisture, gets heavy, and takes an age to dry. Technical blends wick sweat away from the skin, dry quickly, and resist odour — vital when you’re two days into a multi-day hike and far from a washing machine.
Look for a fit that allows full freedom of movement without bunching under a pack’s shoulder straps. Flatlock seams are a huge bonus for preventing chafing on longer days out.

Soft Shell Jackets: Your Versatile Mid-Layer
The soft shell jacket is arguably the most versatile piece of kit in the outdoor wardrobe. It sits perfectly between a base layer and a waterproof shell, offering just enough protection against a light shower or a cool morning without the bulk or crinkle of a full hard shell.
For summer adventures, a good soft shell should be: breathable enough to wear during sustained effort, stretchy enough to allow a full range of movement, and packable enough to stash in a side pocket when the sun comes out properly.
Our top pick is the 5.11 Adhere Jacket. Built with 5.11’s trademark attention to functional detail, the Adhere offers a clean, slim-cut profile that doesn’t scream ‘tactical’ but is packed with performance features. The fabric has excellent stretch, it’s wind-resistant, and the DWR finish shrugs off light rain without issue. Multiple pockets keep your essentials accessible, and the overall cut is clean enough to wear off-trail too.
Recommended: 5.11 Adhere Jacket — a best-in-class soft shell for summer adventures.
Light Outer Layers: When the Weather Turns
Even in summer, the mountains demand respect. A lightweight packable waterproof or windproof is non-negotiable if you’re heading anywhere with exposure. These layers live compressed in the bottom of your pack and barely register on the scales, but on the day you need them, you’ll be profoundly glad they’re there.
When choosing a light outer layer, weight is king. Look for something under 400g that packs down small. Taped seams and a reliable waterproof rating (10,000mm HH minimum for UK summer use) should be standard. Pit zips or underarm venting are a bonus for high-output activities like trail running or cycling.
Layering principle: base layer wicks, mid layer insulates, outer layer protects. Get all three right and you’re weather-proof.
Trousers, Walking Trousers & Shorts
The great summer trouser debate: shorts or longs? Our answer: both, ideally. The ideal setup for summer is a pair of zip-off trousers (legs on for early morning cool, zipped off by midday) or simply packing both options for a multi-day trip.
For walking trousers, you want stretch panels at the knee and crotch for unrestricted movement on technical ground. A DWR coating helps in light rain. Avoid denim and heavy cotton — they’re heavy when wet and dry agonisingly slowly.
For shorts, the 5.11 Taclite Pro 11-inch Shorts are a standout choice. The Taclite Pro fabric is a 65/35 poly-cotton ripstop blend — tough enough for scrambling and bushcraft, but lightweight and comfortable enough for a long day on the trail. The 11-inch inseam gives good coverage on technical terrain without restricting movement, and the articulated patterning means they sit naturally whether you’re crouching, climbing, or just striding out on a long ridge walk. Multiple pockets, a gusseted crotch, and YKK zips round out a genuinely excellent pair of summer shorts.
Recommended: 5.11 Taclite Pro 11-inch Shorts — the summer short that works as hard as you do.
Section 2: Hats & Caps
Head protection is one of the most overlooked aspects of summer kit. UV exposure at altitude is significantly higher than at sea level — your head, face, and neck are in the sun’s firing line all day. A good hat isn’t a fashion choice; it’s a safety one.
5.11 Boonie Hat — Full Coverage for Long Days
The boonie hat has been a military staple for decades, and for good reason. The wide, all-round brim provides excellent shade for the face, neck, and ears — the three areas most commonly neglected and most commonly burned.
The 5.11 Boonie Hat is built from a durable polyester-cotton blend that’s fast-drying and breathable. Mesh venting panels keep airflow moving on hot days, and the hat is crushable and packable — stuff it in a side pocket when you’re scrambling and pull it back out at the summit. The chin cord keeps it secure in wind, and the adjustable sizing means it fits securely even with sunglasses and buffs underneath.
Perfect for: hillwalking, wild camping, festivals, fishing, and any extended outdoor activity where you’ll be in direct sunlight for hours at a stretch.
Recommended: 5.11 Boonie Hat
5.11 Scope Cap — Lightweight Comfort for Everyday Wear
When the sun is out, keeping your head cool and your eyes shaded makes a real difference. Whether you're spending the day outdoors, heading to the range, or simply out and about, a lightweight cap offers comfort without adding bulk.
The 5.11 Scope Cap is designed for everyday performance. Its structured design and pre-curved peak provide reliable sun protection, while the adjustable fit lets you tailor it for all-day comfort. Durable construction means it's built to handle regular use, whether you're on the trail, travelling, or tackling everyday tasks.
Easy to pack and comfortable to wear, the Scope Cap is a practical addition to any outdoor or tactical kit.

Section 3: Boots & Shoes
Ask any experienced hillwalker, trail runner, or outdoor professional what the single most important piece of kit is, and the answer is almost always the same: footwear. Everything you experience in the outdoors is filtered through your feet. Blisters end trips. Twisted ankles on unstable footwear end seasons. Good boots are an investment in every adventure you’ll ever take.
Summer Footwear: What to Look For
Summer footwear requirements differ from the winter and shoulder season. You generally don’t need the heavy leather fortress of a winter mountain boot. Instead, look for:
Breathability: Gore-Tex or similar membranes are brilliant in rain but can leave your feet cooking on hot dry days. In summer, consider a non-waterproofed trail shoe or lightweight boot for dry conditions.
Grip: Vibram soles or aggressive lug patterns are non-negotiable on technical terrain. Even on dry rock, grip matters.
Ankle support: Low-cut trail runners are fine for easy paths. Mid or high-cut boots offer essential ankle support on rough, uneven, or rocky ground.
Weight: Lighter is generally better in summer. Every gram on your foot equates to several kilograms of effort over a long day.
Fit: Always try footwear with the socks you’ll actually wear. Feet swell on long days — allow half a size extra for comfort.

Section 4: Bags & Hydration
How you carry your kit is just as important as what you carry. The wrong pack ruins your back. Not enough hydration ruins your day. Get both right and you’ll barely notice them.
5.11 RUSH24 Backpack, The Ultimate Day Pack
If we had to recommend one bag for summer adventures, it would be the 5.11 RUSH24. This is a 37-litre tactical backpack built to carry a full day’s kit with maximum organisation and minimum fuss.
The RUSH24 has been refined over years of real-world military and professional use, and it shows. The main compartment is cavernous, with internal organisation pockets that make packing and accessing gear genuinely intuitive. The MOLLE webbing system across the front and sides means you can attach additional pouches, tools, or hydration carry as your load demands.
Crucially for summer use, the RUSH24 features a dedicated hydration bladder compartment compatible with most 2-3 litre bladders (including the 5.11 WTS system — more on that below). The shoulder straps are padded and ergonomic, and the sternum strap and waist belt help transfer load off your shoulders on longer carries. Built from 1000D nylon, this pack will outlast most of the adventures you throw at it.
Recommended: 5.11 RUSH24 Backpack — the day pack that goes the distance.
Honourable Mention: The New 5.11 Allhaula 30L
If you're looking for a more compact alternative to the RUSH24, the new 5.11 Allhaula 30L is well worth considering. With 30 litres of storage compared to the RUSH24's 37 litres, it's better suited to day trips, commuting, or shorter outdoor adventures where you don't need to carry as much kit.
It still offers the durability and thoughtful organisation you'd expect from 5.11, while keeping the overall size and weight down for a more streamlined carry.

TacTree Water Bottle
Staying hydrated is one of the simplest ways to keep your energy, focus, and endurance up during a day outdoors. Even mild dehydration can affect both physical and mental performance, making regular water intake essential whether you're hiking, working, travelling, or spending time on the range.
A reliable water bottle makes hydration easy wherever you are. Keep it in your backpack, vehicle, or at your desk so you always have water close to hand. Unlike disposable bottles, a reusable bottle is built for daily use and is ready to refill whenever you need it.
The TacTree Water Bottle is made from durable stainless steel to withstand everyday use. Its double-wall vacuum insulation helps keep drinks cold for hours or hot when the weather turns, making it suitable for every season. The leak-resistant lid gives you confidence to throw it into your bag without worrying about spills, while the generous capacity means fewer refill stops throughout the day.
Whether you're heading into the hills, travelling to work, or tackling a busy day outdoors, the TacTree Water Bottle is designed to keep your drink at the right temperature and within easy reach.
Recommended: TacTree Water Bottle — dependable hydration for every adventure.
Section 5: Essential Carry, The Kit That Could Save Your Life
The best adventure is a safe adventure. When you’re pushing into remote terrain, operating in variable conditions, or simply spending long hours away from help, having the right essentials on your person isn’t optional — it’s basic responsible practice. Here’s what we never leave home without.
First Aid Kit
Accidents happen. A stumble on a rocky path, a cut from a blade, a blister that turns into a hotspot, a sprained ankle miles from the car — none of these are rare events in the outdoors. Having a well-stocked first aid kit means you deal with problems before they become emergencies.
The Compact Universal First Aid Kit from our range is exactly what a day or weekend adventurer needs. It covers the most common outdoor injuries: cuts and abrasions, blisters, burns, sprains, and more. It’s compact enough to drop into a side pocket of the RUSH24, robust enough to withstand a full season of outdoor use.
We’d also recommend supplementing your kit with: blister treatment (Compeed pads), a triangular bandage, a foil emergency blanket, and any personal medications. Know how to use what you carry — a first aid qualification is one of the best investments any regular outdoor adventurer can make.
Recommended: Compact Universal First Aid Kit — because being prepared isn’t pessimism, it’s professionalism.
Leatherman Signal Multi-Tool: One Tool to Rule Them All
If the first aid kit is your safety net, the Leatherman Signal is your problem-solver. Few pieces of kit earn their weight so comprehensively in the field. A quality multi-tool is one of those items you don’t appreciate until you need it — and then you can’t imagine going without one.
The Leatherman Signal is purpose-built for outdoor and survival use, and it shows in every tool choice. The headline features are compelling: a full-size knife blade, a fire-starting ferro rod, an emergency whistle (built into the handle), saw blade, hammer, wire cutters, pliers, multiple screwdrivers, a can opener, and more. Unlike some multi-tools which feel like they’re trying to do too much, the Signal’s tool selection is curated for real-world outdoor use.
Built to Leatherman’s legendary standards from premium stainless steel, with a 25-year guarantee. Whether you’re repairing broken kit in the field, processing wood for a fire, building an emergency shelter, or simply needing a knife for camp cooking, the Signal has you covered.
Recommended: Leatherman Signal Multi-Tool — the outdoor multi-tool that punches above its weight in every situation.
Casio G-Shock DW-5600: Time Keeping Built to Last
In an era of smartwatches with 24-hour battery lives and touch screens that fail in the rain, the Casio G-Shock remains the go-to timepiece for serious outdoor use. There’s a reason this watch has been worn in conflict zones, on expeditions, and through extreme sports for over 40 years: it simply doesn’t stop.
The G-Shock DW-5600 Series Revival is the modern iteration of the original G-Shock — the watch that started it all. It’s shock-resistant, water-resistant to 200 metres, has a battery life measured in years (not hours), features an electroluminescent backlight for night use, a countdown timer, stopwatch, alarm, and dual time zone display.
For summer adventures, the DW-5600 is the perfect wrist companion. Light, tough, functional, and with no charging required. It doesn’t care about signal strength, GPS satellites, or whether your phone battery is dead. It just tells the time, every time, in any conditions.
It also looks genuinely cool — the DW-5600’s clean, square case and classic dial design have become iconic. This is a watch that works as hard in the mountains as it does at the pub afterwards.
Recommended: Casio G-Shock DW-5600 Series Revival — the indestructible timepiece that serious adventurers trust.
