Great feel!
March 09, 2012

I'm 5 11 and 160, a large is a great fit ( usually I wear a medium). I wanted it to fit snug but not tight. I feel like it fits me in such a way that I can wear it alone or under another shirt. Love the feel of the material and the construction of the shirt is top quality!

Pros: Great design, Build quality, Performance, Ease of use, Cons: Cost

Just got one of these, and the fit and quality are typical of Arc'teryx (better than pretty much anyone else). The material is quite light, but provides a fair bit of warmth. Likely to be a bit too hot if you are really working. Does not bind under other jackets. beware, the size chart is a bit misleading, as I would personally go for the next larger size than what is recommended, especially if you are tall. I have a 38 chest, so I ordered the small, which felt like it was painted on and did not even cover my belly button.


great zip top
February 26, 2010

A great base layer. It's so comfortable I don't even want to take it off after skiing. I love the chest zip pocket too.I like it.

This is the second Rho LT I had purchased, but just different color. The products from Arc'teryx are always excellent, and with confidence. This shirt not only provides that, but a also fits my body at every inch. The best shirt I ever own.

The best shirt!!
June 25, 2012

Someone said that it's size run small. Yes! this is tight but very comfort. I bought it for base-layer for winter and main wear for spring & fall. It is good for climbing also cycling. I recommend to all of people.

Pros: Great design, Build quality, Performance, Cons: Cost

Super comfortable
October 06, 2009

It is super comfortable, warm and light, and has the great Arc'teryx quality. The fabric feels great against the skin. Especially when living in cold northern climates

Good Product
December 07, 2009

I agree that the Sizing seems to be a little off unless you want to wear the product extremely close to the skin. I would go one size up if you want to wear it tight and 2 sizes if you want to wear it like a shirt. The product looked good though.

Great piece, not for me
March 03, 2010

I thought this would be a little heavier and not such a close fit, but it is what it is, another great Arcteryx piece with a great fit and a great collar. It fits close, think Under Armour. It is nice like I said, just not what I was looking for. I am 6'0", 150lbs, and a medium fit me like a champ, plenty of arm length and plenty of length in the back.

Know what you're getting into: this shirt is sized as a tight base layer. [sel-ect ]your size accordingly. I normally wear a medium, and a large gives me a looser fit on these shirts but the sleeves are the perfect length. They are very comfortable, provide great warmth for their light weight, dry quickly, and look excellent. The pocket is handy for something small. I wish the zipper were a little bit longer. My favorite color is the mahogany. It looks very nice.

Ultra-sweet Top
March 29, 2011

I love powerstretch for aerobic excercise, it is outstanding at wicking away the moisture and keeping your skin pretty dry. Very warm, medium wind resistance and breathes enough so that you can go, go, go.... Great for bicycling in SF winters, going to use it today for a cycle through the bay...not sure about how durable this material can be, best not to go bush-wacking with it! Arc is a little expensive but I find their stuff outstanding and this was Made in Canada so it works for me. I also used the 20 percent reduction from Altrec so price is not that bad. Sizing is small but this is normal for Arc, I usually wear a large but need XL here.

Great looking, great quality. Fits a little tight under the armpit - but maybe it will stretch a bit in time. I am 5'11" 160lbs and a Medium is the best fit. Went with the Paprika so pretty sure I wont be lost in the backwoods. Pricey, but it's Arcteryx, worth every penny.

Pros: Great design, Build quality, Performance
