Rated 5 out of 5 by from Perfect for those warmer days The new lightweight capilene long sleeve crew, cousin to the midweight, is an ideal alternative baselayer for when temperatures begin to climb into the upper 50s and above. Or take off the outer layers and wear it alone on those days in the 70s and warmer. Great for trekking & hiking (I've worn it in the Himalaya, the Cascades, the Rockies, and good ol' Michigan. But really nice for running, working out, and biking (mountain & road) -- anything and all things active. It reminds me quite a bit of the old Patagonia silkweight capilene & I wear it in similar circumstances (see above). If anything, I'd say it breathes even better, keeping a body cooler in temperatures running up toward the 90s thanks to its lightness and weave. Of course, anybody's going to sweat on a warm day, but this shirt rests light on the skin & lets in a breath of cooling breeze. Dries super fast! As discovered when a rogue meal slipped off the mess plate onto my belly. Rather than take the shirt off, I just rinsed and scrubbed it clean with my hands at a nearby tap. I swear it dried from body heat in just 5-10 minutes. As to sizing, I'm 6'3" and 200 lbs. I wear an extra large. The sleeves come right to the bottom of my palm where it turns into wrist -- maybe just a hair longer than my midweight crew but certainly within the inch or inch and half range around the wrist where I call it a good fit. I'll wear the sleeves all the way down for the sun protection or in cooler weather, but they nicely roll up to the elbow, too. The slim fit is perfectly draped and not constraining. Like the midweight, I'd call this essential gear. I'm buying a couple more.

Rated 5 out of 5 by from Excellent Perfect - as base layer or as-is for warmer weather active sports. This is the third generation of the product I have used and I am entirely happy with the performance.

Rated 5 out of 5 by from Perfect hiking top for late-spring, summer I've worn this top running a half-marathon as well as on 10-mile hikes and while climbing a mountain. This thing is a great base layer. It dries quickly and is so light you barely notice it. The fit is nice and slim. Despite the long sleeves you won't feel overheated wearing it in 80-degree weather, but if it gets below 70 and if it's breezy at all you'll want to pair it with a heavier top because it doesn't keep you warm in even the mildest of conditions once the temp drops. Outstanding product. I'm going to buy more.

Rated 5 out of 5 by from Absolutly the King of Wicking I have used this long sleeve top on many, many occasions over the past two seasons and I think it is fantastic. I have used Capilene for well over ten years and I find the comfort and wicking ability of this material to be second to none. Also no synthetic stink, launders well (don't dry!!). What I love about this lightweight top is in winter I use it next to my skin and I can be assured that sweat is moved off of my skin ASAP, no chill or dampness against the skin, I typically have my Capilene 2/Zip turtleneck on top of this garment. In summer I use it as a hiking top, love being able to have the sleeves down or pushed up. Lastly the fit is great, I'm 5"10" and 150lbs and the Medium just "floats" on my body, no binding, very comfortable and a great top in the sleeping bag. This shirt is like silk on steroids..Outstanding!!!

Rated 3 out of 5 by from Very comfortable with great temperature control I'm happy to have found a lightweight base layer that is very comfortable with great temperature control. Just loose enough to were it does not pinch or rub and just close fitting enough to not feel bulky under other layers. I've worn this mt. biking in cooler weather as well as backpacking in the fall. Works great on a hike when there is a little chill in the morning which quickly warms up during the day. The only unfortunate part is that I don't know about the durability or longevity of this shirt. I've owned mine for only a couple of months and used it on two separate hikes and I've noticed that I've worn a couple small holes in the shirt where the waist belt of my backpack had rubbed on the shirt for a few miles. I was able to exchange the shirt no problem for a new one, but if this one does the same thing this shirt will be going back to REI for good and I will change my review. IMO, a shirt with this type of price tag should last a long time.

Rated 2 out of 5 by from LONG Sleeves I have a Capilene lightweight long sleeve shirt that is about ten years old. I still love it. I just bought two new ones, but found the sleeves WAY too long. I bought the large size, like before. The new shirts also have no cuffs, which seems like cost cutting. I'm not happy. I have worn one shirt, but will return the other.

Does this material shrink at all after washing?

This top is made from 100% polyester and will not do much in the way of shrinking.

how much SPF does this provide? I was hoping to find it in white for hiking on hot sunny days, to stay cool, dry, protected from the sun.
