Straight Fit Stretch Cavalry Twill Trousers with 7 Pockets

Key Features

A cotton-polyester-elastane cavalry twill that flexes with movement and wears like a work trouser.

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

Every belt loop is reinforced for extra support with a loaded belt.

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

A classic straight fit that reads as an ordinary trouser at work or in town.

Reinforced stitching at stress points for years of daily wear.

The 5.11 Defender-Flex 2.0 Trousers are straight-fit everyday trousers that look good and get the job done. A stretch cavalry twill of cotton, polyester and elastane gives clean style with the strength to handle long days and repeated wear, ready for the range, a walk in the woods or the office.

Five-pocket styling with a zip fly and logo shank closure gains back yoke utility drop pockets, giving seven pockets in all, with a coin pocket at the left hand pocket. All the belt loops are reinforced for extra support at the waist and Nylon 6 reinforces the front hand pockets where knives and keys wear.

About 5.11 Tactical

5.11 Tactical extended its Defender-Flex denim platform into twill with the Defender-Flex Pant, and the 2.0 refines that everyday trouser. From its California base the brand, independent since 2003, designs civilian lines with the hidden pockets, reinforcement and stretch it puts into duty gear.

Trousers Fit Guide

Looser Tighter
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

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.
