Product Description Item No.   10184204

The Arc'teryx Men's Gamma LT Jacket is a lightweight soft shell for active outdoor adventures from hiking to rock climbing as well as heading to work. The athletic fit of the Gamma LT looks good in any situation and is very durable, yet soft to the touch. It's weather and wind resistant, so you can take on fall, spring, and a touch of mild winter weather. A durable water repellent finish helps light moisture roll off the fabric instead of soaking in. The inside is soft against the skin and the stretchy wrists pull close without restricting them to block drafts. The two zippered hand pockets are placed high so you can wear with a harness or pack and continue on your way through the mountains.

Rated 5 out of 5 by from Sweet Jacket, Fit and Finish are Excellent!! I heard Arcteryx was the bomb about a year ago, but never pulled the trigger on one, boy am I glad I finally did after snagging one on sale! The fit and finish are incredible, the jacket oozes quality. I was a bit preturbed to see that this was made in China, as are a majority of current Arcteryx offerings (or so I hear), but some good products can come from there, and this is one! It is a great light jacket, I don't anticipate it doing too well in anything less than 40 degrees or so, but this will be an everyday wear for me in the mild winter days. Very pleased and I looks forward to adding more Arcteryx to the wardrobe.

Rated 5 out of 5 by from Great & Versatile Lightweight Jacket I've owned the Gamma LT for about a month now. It fits well and it very comfortable. I've worn it while mountain biking, running a few times, and around town casually. I have virtually zero complaints about the jacket thus far. For casual wear, the sleeves on the jacket are slightly long and I find them bunching up at the wrist. However, when wearing it while biking I actually liked the longer sleeves as they don't ride up when your arms are outstretched. It has a pretty true "athletic" style fit and is trim around the underarms. It's warm down to temps around +40F, after that you'll need more layers underneath. It handles wind surprisingly well being so thin. Highly recommend.

Rated 5 out of 5 by from Go to jacket for mild weather and precipitation I love this jacket! I bought for my bicycle commute to work, but I ended up wearing it most of the time, as long as the weather was 40 or over. Even when the weather is colder, a thin fleece underneath extends the range of this shell quite a bit. For hiking, I am definitely good in this shell alone with a thin to medium weight base layer in 30 degrees or a bit lower.,,,,The shell is built like a bank vault, and sheds mild precipitation (mist, sprinkles, light snow). I am 6', 180 pounds, and the medium fits close but well, and it leaves enough room for a thin fleece.

Rated 5 out of 5 by from Solid, light jacket. Made really well - no frills, does what a light jacket should.,,,,Practically waterproof from the limited exposure to rain i've worn it in.,,,,Comfortable, good athletic fit, etc.,,,,Overall, I would recommend if you want a light, not warm, jacket for aerobic outdoor activity or walking around in warmer fall/cooler spring temps.,,,,

Rated 5 out of 5 by from My new go to jacket!! I ordered this jacket in size L. I'm 5'11 and 189 lbs. This is my new go to jacket. It really fits me perfect. Can wear up to a long sleeve shirt underneath. Just what I wanted. A lightweight, wind/weather resistant jacket I can wear fall to spring. Very well made. Looks great. Falls in line with my other Arcteryx stuff. YEAH!!

Rated 5 out of 5 by from Fantastic product at any price. Or none. I stumbled into owning this jacket (Don't hate me, Moosejaw) and I haven't taken any other jacket camping this season. The fit is good you could wear it to the opera and yet allows for dynamic movements with no restriction. See the many other positives for specifics.

Rated 5 out of 5 by from Arcteryx Jackets = Excellent Quality My son has had his Arcteryx winter-weight jacket for quite a while and loves it, so wanted this light-weight jacket for warmer weather. He likes the style and comfort. I'm impressed with the quality and easy care! Great jacket!

Rated 5 out of 5 by from Fit is Awesome, Quality is Amazing As with all Arcteryx products, you will not be disappointed. I love the fit of this lighweight jacket, so I am planning to step up and order the Gamma MX shortly. This is a good 3-season jacket, but a little light for winter.

Chest / Bust - Measure around your chest / bust, holding the measuring tape under your armpit.

Waist - Measure around the natural waist, which is often the narrowest part of your waist.

Hip - Measure around your hips at the widest part.

Sleeve Length - With your arms in a slightly bent position, measure from the center of the back of your neck, along the length of your arm, to the wrist.

Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.

Head Circumference - Measure the full circumference around the widest part of your head.

Hand Length - Measure from the tip of your middle finger to the base of the palm.

Hand Width - Measure the circumference of your hand around the knuckles, excluding the thumb.

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.
