All-day wear with freedom of movement
DUER's Performance Denim is designed with 360° stretch, so these jeans are made for people on the go who want classic denim that keeps up with a full day of activity. The cotton and performance fiber blend is intended to offer all-day comfort, with an ergonomic seamed crotch for added ease of movement.[2,3]
Extended Wear Performance Denim
Equipped with antimicrobial protection, these jeans resist bacteria and odors through a protective material. This feature is designed to allow you to wear the denim more and wash it less, enabling extended wear between cleaning cycles.[2]
Staying cool and dry in any season
DUER's Performance Jean blends 28% COOLMAX® fibre technology into the denim for moisture-wicking and temperature regulation, helping you stay cool and dry. The brand describes the fabric as adapting to both warm and cool conditions, making these jeans a pick for all seasons and settings. The blend also includes organic cotton for a classic denim feel and LYCRA® for stretch that moves with you.[1]
Product comparison
Compared within this brand.
| Medium-Blue Performance Jean Straight, Slim Fit: Choose this if you want a straight, slim-fit medium-blue jean built for movement: the stretch denim blends cotton with COOLMAX polyester and spandex, and DUER says the Performance Denim offers 360-degree stretch for freedom of movement, plus COOLMAX moisture-wicking and an antimicrobial treatment for odor control so you can wear it more and wash it less. It's a classic denim look with faded thigh panels and whiskering, and care is simple — machine wash cold, tumble dry low. Note that DUER states the final wash and colour may vary between pairs.[1,2,3,4] | Indigo Coolmax® Performance Jean Slim Fit: Choose this if you want a slim-fit jean built for active days: the quick-dry denim uses COOLMAX all season polyester within a 70% organic cotton, 2% LYCRA elastane stretch blend that DUER markets for wicking moisture and regulating body temperature, and a hidden gusset is designed for flexibility. The construction leans durable, with triple stitching and double-layered back pockets for strength, and a reviewer reported no bagging out or wearing thin after 6-plus months of heavy wear. A tester found them noticeably cooler in warm weather, though still jeans.[5,6,7,8] | Performance Deep-Indigo Jean Straight, Slim Fit: Choose this if you want classic-looking slim-straight denim built for movement and travel: a stretch cotton blend with COOLMAX polyester (77% cotton, 21% polyester, 2% spandex), a signature gusset for full range of motion, moisture-wicking to keep you cool and dry across warm and cool conditions, and an antibacterial treatment meant to prevent odor. One reviewer wore them through a 12-hour car ride without discomfort and prefers DUER to some other brands, though they are not the lightest or smallest for packing and experiences with the stretch vary.[9,10,11,12,13,14,15,16] |
