Rated 3 out of 5 by from Not the same fabric of recent years Hi, I've been wearing Patagonia's capilene for many years, it's my first choice for comfort, wicking & functionality. But, this newer, (apparently more post-consumer fabric) does not feel as nice, it's more synthetic- feeling. The worst problem is this shirt begins to smell shortly after sweating in it. I do not have the problem with my older capilene shirts, (& I am a fit, pro-guide, with a healthy diet etc., so it's not me). I'm all for recycling & supporting sustainability, but I prefer not to smell around my clients & friends! Happy hiking.

Rated 5 out of 5 by from Opens up a myriad of cold-weather possibilities Working to extend my bike riding deeper into the fall and winter, it's the only exercise I enjoy: pedaling in the woods. I've heard about the importance of a base layer that's synthetic, how it beats cotton, how it wicks moisture out and traps heat in. Well this top lives up to the hype. Thanksgiving morning ride in 45 degrees and I had all kinds of endurance due to not being too cold on the downhills. SO glad I bought a base layer, and this one gets the job done comfortably. Thumb loops are great, they make it stay down over my wrists when I bend to reach the handlebars. The dude at REI helped me find this good value Patagonia gear.

Rated 5 out of 5 by from An improvement over older Capilene My reference point is Capiline mid-weight baselayers I've had for 15+ years (yes, they've lasted that long). They're the solid blue versions before Patagonia ever offered the more recent striped or two-tones. The current version is much nicer for the following reasons. First, they're just as warm. Second, they're cut a wee-bit looser (though not baggy at all which would be bad) compared to my reference so don't hinder active movement, Lastly, they're easier to layer because the top surface offers less friction. Even when I'm wearing something as snug as my R1 1/4-zip and pull it off, my Capilene top tends to stay put. If I try that with my older Capilene, the R1 pulls it off my top. Can't wait to get some more.

Rated 4 out of 5 by from Good midweight top I find the Patagonia a very good mid-weight base layer. The fit is a "comfort" fit not an athletic fit. (I will likely go for medium next time for a better close to the skin fit. (6'0", 190) The sleeve length is good and the thumb straps are ok. I prefer a thumb hole in the sleeve.

Rated 5 out of 5 by from LOVE THEM SOOOOO MUCH! I love them & have worn them Flyfishing, Float Tubing, Hunting, Skiing, Hiking- Heard a few people saying their a little big but I think thats because everything else shrinks so fast! (Haven't noticed any smells yet though). Great product, (was surprised the TOPS are a few dollars more) But I'm a HUGE fan! (Wife says they look cool & she's super HOT). I wash in Gentle cycle & air dry. If your an experienced outdoors person you know how to take care of your equipment! Great price, Great for yourself, or even makes an outstanding gift perhaps. (Couldnt go wrong giving someone these!)

Rated 5 out of 5 by from Best Active Underwear I know of Fantastic, wicks moisture so you can stay warm as expected. Very comfortable. The new versions are much more comfortable than the older versions I have owned.

Rated 2 out of 5 by from Neck Uncomfortable I love Patagonia, but when the neck zipper is up all the way it pushes too hard under my chin. I had to return it and get the regular top instead. Patagonia: make the zip-neck more comfortable!

Rated 5 out of 5 by from Upgrade of a favored old garment I still own--and wear--a 20-year-old Capilene midweight top, but its insulating properties have diminished somewhat with the gradual stretching of the bottom hem over time. Time for a new one, which was initiated on the slopes. The leaner, more athletic fit corrected the lost heat problem, and otherwise I hardly knew I had it on. Excellent freedom of movement and wickability, and if it is as durable as the older one, I know I'll still be wearing it after another 20 years.
