How many base layer fleeces can you look at? Seriously, this one is great and an excellent example of why Arc Teryx maintains the rep that it does. Very soft to the skin, superior articulation, smooth surface (great for reducing friction under your mid/top layer), and nice cut. And as a word of caution to those new to the arc teryx brand, the tops are cut small. Honestly, they are cut for a woman of petite frame, take my word for it.

I got a small. I am 5ft6 and 130lb. It is so nice. It looks great and has a great fit. I got the green color and it is darker than it looks online.

The most flattering and stylish thermal top ever! Beautiful fit and very warm. I would suggest going up 1 size if you want to wear it alone as a longsleeved shirt for casual going out. I got a size small, I'm 5'2" and weigh 115 my measurements are true to the chart but I'm going to get another in Med. so i can wear it about and not feel as self conscious. Still love the small for a base layer though. I wish I had gotten two, or three or.....

The fabric is very warm and the cut is very fitted. The flat seams make for a nice finish. Also, the shirttail is long enough to stay tucked in.

just spent 4 days in the norwegian mountains and wore this all the time. warm, light and comfortable and a definite part of my next hiking trip

This top is fantastic. i got the wasabi colour and it's more like lime than the rather dull looking green in the picture. I bought an S and it does fit more snug than S for my Arcteryx Rho AR. i think it's the material that's just more clingy. so if you don't like clingy, i'll recommend to size up.

Excellent top, wonderful layering piece or great when just warn alone. Highly recommend this top!

I recommend if you are a size small you get a medium. This a very nice shirt-jersey to wear. I got two of them for my trip to the Everest, it was fantastic.

Nicely shaped, attractive style, but the olive green, aka Split Pea, was too drab for me.

Love this top. Comfy & not too tight. Wore it as a base layer under fleece & jacket for snowshoeing. Love the green color too. I did think it was kinda expensive compared to others, but I would pay it again since the style & color are just me...

I have only gotten these two days ago, I haven't been able to take them off. JUST LUUVE IT!!! They are soft, breathable, and quite stylish. I am usually always cold, and this base layer, even though very thin, keeps me feeling warm most of the time. I would say this is definitely a keeper!!

Fits perfectly, and performs well. Makes a great base layer for chilly to freezing days. Soft, breathable, and looks great alone. The zip neck is very comfortable helps to regulate temperature throughout the day.
