The Gamma LT is the result of intelligent, purpose driven design and the Arc'teryx commitment to craftsmanship. Made from lightweight, hardwearing Wee Burly softshell fabric, a DWR (durable water repellant) treated nylon/polyester double weave, the Gamma LT is strong, light and provides moderate warmth and weather protection. The fabric blends wind resistance with air permeable comfort, has elastane fibres for built-in two way stretch, and is exceptionally durable for its weight. Its wind and water resistance is complimented with a textured backing that adds thermal comfort and moisture transport during active use across a range of weather conditions and levels of activity. This versatile performance makes the Gamma LT an essential softshell for active alpine and backcountry endeavors. REFINEMENT AND INNOVATION Refinement and smart innovation are Arc'teryx design obsessions. To facilitate heat dump without inadvertent opening, the Gamma LT employs the ingenious No Slip Zip. The zipper's unique construction involves a series of bumps on the top few teeth to prevent self-opening, but, as in many Arc'teryx pieces, the zipper may be rapidly opened with a single hand for almost instantaneous heat dump. This seemingly little thing clearly shows the Arc'teryx attention to detail. MOVEMENT AND FREEDOM Alpine versatility requires exceptional freedom of movement, so Arc'teryx leverages articulated patterning, underarm gussets and stretch materials to help the Gamma LT move with the body. The Arc'teryx regular fit fits easily under a belay parka, allows room for midweight layers, yet is streamlined and athletic. The Gamma's hip length hem and streamlined patterning allow it to lie comfortably under a harness or pack belt. Stretch gusset cuffs provide a secure fit, but push up easily for ventilation.

A great light weight summer jacketBy: captainbackfire on 31 July 2019I mainly use this jacket for going to work and light walking. It is very light weight, cut well and feels very comfortable. It is shower resistant. I think the cuffs are a very neat design.
Incredibly comfortable and versatileBy: yadmat at Arcteryx.com on 31 July 2019This was the piece of clothing that really switched me onto Arcteryx. The medium size fits my 6' 1" 168 lb frame perfectly. The longish arm length and slight drop back mean the jacket works well for biking. It keeps moderately heavy rain out for at least 10 mins. The soft, quiet fabric is tough, surviving hard scrapes against bricks and stone. Best of all, it works perfectly with an Atom LT and together they make an incredible 3-in-1 system that keeps sees me through autumn-spring in the UK on all but the few coldest or wettest days.
