Perfect to keep you warm on a cooler day without overheating you. Incredibly lightweight and comfortable material and a beautiful color on top of that. (Northern Light-blue) Great for any outdoor activity in the fall!

Used as base layer for skiing, with a turtleneck over and then my jacket. Was a bit worried about the v-neck but it was more like a crew than a deep v. Actually was almost too warm on 30 degree days! Handled sweat well and didn't stink. I'm tall so went with XL because I was worried about sleeve and back length - probably would have been fine with a L.

This is a great, multi-purpose shirt! Keeps you dry, and works as a light thermal, or just sun protection. You can't go wrong with patagonia!

I love this shirt. Wore it over a thin UnderArmour T-shirt for a week-long canyon backpacking trip in Utah and found it the most comfortable and easy-to-layer long sleeve I've ever had. Moves well with me through hiking, climbing, running, frisbee, biking, and right now just bumming around getting ready for bed. I got the XS after trying on different sizes because it fit better, though I usually wear a small (4-6) in other shirts. Longer in the back so less peek-age, and I chose the v-neck because it's easier to get on and less constricting than the regular crewneck. Did I mention I love it? Love it. I'm here for more colors that I can't find in stores.

This piece can be worn as a base layer or as a cover up on chilly spring and fall days. I throw it on when I'm cold indoors as well. I keep it stashed in my bookbag while at work and put it on as a coverup while at the beach. it has become an staple in my wardrobe. HIGHLY recommend it. It true to size and the V-neck is so slight that I'd consider it a fun twist on a crew neck.

I bought one of these for a trip to Norway. It was great by itself during the days, under my rain gear during a rainy hike and under fleece in the cool evenings. But all that is no surprise.
The thing that I have found it to be wonderful for is running. In Texas I rarely need much extra warmth on my runs. But I have found this top to be comfortable in a wide range of conditions. I think I like it best when I am going for a morning run and the shock of going from a warm bed to short sleeves is too much. It is just enough to keep a cool breeze off my skin, but it also breaths wonderfully as I warm up. The fabric is soft and smooth, never itchy. It has held up to dozens of washes. It is long enough for my long arms. Basically I'm going to buy a few more in different colors.

i use it for hikes, bike rides, class...you basically don't sweat through it ever. ... and u will look hot in it!

I bought this under layer for a trip to Peru in December and it was AWESOME!!!! This shirt was thin enough to keep me warm and wicked away the sweat as I was hiking up to 15,000 ft. It is not scratchy to the skin like other brands and was extremely comfortable. I will buy Patagonia again.

nice base layer with a nice smooth feel to its fabric. it has lots of venting in the areas where you tend to sweat and is cut to move with you.
