Arc'teryx Gamma LT Pullover Softshell Jacket- Men's - 2007 BCS

I have 2 of these and whether I'm downclimbing a sandstone chimney outside of St. George or playing pollywog in some Zion slot, there's no sign after washing...they hold the business end afloat...best $100 garment I've ever purchased. I even wear this action to work with khakis...I'm buyin more...make more colors please. fi-sta'

My wife uses a Mountain Hardwear Transition Zip-T which is windproof and breathes really well, and I had used a Patagonia Houdini wind jacket (very fragile material). After ordering both this and the Transition was a bit snug for me (that's how its supposed to fit), so I kept the gamma LT - and after climbing in it around Salt Lake City and City of Rocks ID I really like it.
Pros: Breathes like crazy, stretches very well, very abrasion resistant even on granite, and cuts the wind as much as I need it to. My wife is always cold and I'm usually too warm.
Cons: The absolutely perfect fit would be between this and the Transition, but I can still layer a thick baselayer under if I need. Also a bit more expensive than the Zip-T.

This is probably the best very light softshell jacket that I have found. Most others seem to think softshells require a significant amount of insulation in the form of fleece or brushed lining, which for high intensity activities is totally non-functional. Very light, but the interior is not totally raw and is comfortable over bare skin. This is perfect for days where a shell is overkill or during aerobic activity. Highly recommended

So many companies are making these "softshell windshirts" getting away from the garbage bag feel of older windbreakers and going to the "stretch woven nylon" for movement and breathability. I have three of these all from different companies and this one is one of the better out there. Fit is tailored, but allows for a layer or two under. Drop hem in rear gives style and function. It will break some wind (hahahhaha), but also let some in (no drawcord), so its great for mid weather ranges when you need a little breeze every now and again. Great for trail running, hiking in cool weather, or chillin' as the fit will allow a button down or something under it. 5'10'' 190 and large fits me as described.

If your looking for an extremely light weight jacket that will block a good bit of wind and keep out rain (except for a down pour) then this is a must have. Used it for running trails in the mountains and while mtn. biking and I will never leave home with out it. I'm 5'10" 165lbs. and a med. fits me perfect with a t-shirt on underneath.

I got this jacket/windshirt a month ago, and its been with me on several climbing trips since then. Absolutely great jacket. The fit is trim but not tight.
Pros:
Breaths like crazy, cuts the wind, holds up in a drizzle, drys super quick.
Cons:
Pricey, no hook-and-loop closures for the wrists.

If price isn't an issue, it's the perfect pullover... you're gonna like it.
black is nice enough to look nicer than casual at work, too...but highly functional when not locked in a cubicle during daylight as well.

This shirt was a little lighte than I expected, however it is a great in between layer in Maine in January. I expect to be skiing with this as an outlayer on the those warm spring days. Blocs the wind really well, but based on the price I thought it would have a little more weight to it.

I love this jacket for late Spring to early October. Breathes really well, warms the body well when needed and holds off the rain on drizzly days. Great for hiking and of course biking. Only downside is the lack of hem drawstring but I added that and am now ready to go..... It is a bit pricey but Arc is really high quality - take a look at the seams! How many stitches per inch???

Use: I got this piece as a go-between for inside and mild outside use. The softshell is relatively quiet and the pullover style allows me to wear this inside like a sweater (even at work over a dress shirt) without feeling like I'm wearing a (heavier) jacket. Also layers great with my windstopper vest. Have had this a few weeks now. Very satisfied.
Fit: I'm 160, 6'0'' and ordered a large but returned it for a medium. Sleeves and torso could be just a smidge longer (read: half inch) but is fine as it is, and Arcteryx's cut is already longer than many competitors. Gussetted underarms work well and keep this from riding up at the waste and in the sleeves.
Design: Initially I expected some sort of lining, but only microfleece on collar and cuff. Really just a super stretchy cut of softshell fabric. Great mobility. Very light - hardly know I'm wearing it. Provides protection from the elements but is definitely no 3 ply goretex. Serves it's role well.

JAS in Connecticut

This is great for cool weather, not for cold. It's pricey for what you get (just a breathable windbreaker), but it is the most comfy windbreaker I've ever seen.
