Straight Fit Stretch Denim Jeans with 7 Pockets and Discreet Trim

Key Features

Lycra T400 Tough Max mechanical stretch denim that flexes with every step and recovers its shape wash after wash.

Classic five-pocket styling plus two back yoke drop pockets sized for a phone or spare magazine.

A plain shank button and unbranded rivets keep the jeans looking like jeans.

Nylon 6 lining inside the hand pockets stops knives, keys and clips wearing through.

A shaped waistband improves fit and reduces gapping when bending or moving.

Strengthened belt loops carry a gun belt, tools or keys without stretching out.

The 5.11 Defender-Flex Straight Jeans are the answer to years of searching for a denim that meets 5.11's standards. A cotton-polyester denim with Lycra T400 Tough Max mechanical stretch moves with the wearer and recovers its shape wash after wash, so the jeans never bind and never bag. The classic straight cut looks right anywhere from a weekend in the hills to a night out.

Five-pocket styling gains two back yoke utility drop pockets sized for a phone or a magazine, giving seven pockets in all. A non-logo shank button and non-logo rivets keep things discreet, while reinforced belt loops and Nylon 6 reinforcement inside the hand pockets add years of service. A contoured waistband improves fit and reduces gapping when active.

Trousers Fit Guide

Looser Tighter
Relaxed
Relaxed

The loosest cut through the seat and thigh, with a straight line down to the leg opening for maximum room to move.

Regular
Regular

A balanced fit with space to move without feeling baggy — straight through the knee to the leg opening.

Straight
Straight

A clean, straight line from thigh to ankle with a slight taper at the leg opening for a tidier finish.

Slim
Slim

Cut close through the thigh and knee, tapering to a slim leg opening for the trimmest silhouette.

Sizing Instructions

How to Measure
Use your chest, neck, and arm length to find the right size for tops and outerwear. Use your waist measurement — where you actually wear your trousers — for bottoms and belts.

Neck
Measure around the base of your neck, where a collar would sit.

Chest
Measure under your arms and around the fullest part of your chest, keeping the tape parallel to the floor.

Arm Length
Slightly bend your elbow. Measure from the center back of your neck, over the top of your shoulder, and down to your wrist.

Pant Waist
Measure around your natural waistline — where your trousers actually sit, not necessarily your narrowest point.

Hip
Stand with your feet together and measure around the fullest part of your hips, keeping the tape parallel to the floor.

Inseam
Measure from the crotch straight down the inside of the leg to your ankle, or to your preferred trouser length.

Sizing instructions diagram
Measurements are approximate — for the best fit, compare against a similar garment you already own.
