Patagonia Wool 2 Zip Neck Top - Long-Sleeve - Men's - 2006 BCS

Wore this winter backpacking in single digit temps and it did ok. But the fit is way loose for a base layer. Probably should drop a size down. Plus the zip neck is crap. It feels weird next to the skin on your neck and you feel the cold zipper all the time. Plus the collar is way to high. Better off going with the crew. Its really thin too.

Great materials, fits a long torso well. Zip front is generous. Good elemental component of a layering system. The wool weight used is great for 3 season wear. The only thing that would improve it would thumbholes.

Very nice to have when skiing in not-too-cold weather. The zip allows to regulate the temperature very nicely.

very warm yet very light, can be worn in almost any condition. Excellent as a stand alone base layer under a rain coat in cool, heavy rain. fits snug, sleeves are a little longer than normal. cuffs tend to stretch easily and do not return to tight fit. Like all Patagonia gear, it is overpriced.
despite the ridiculous prices, Patagonia has by far the best baselayers (especially wool) of any brand (but lousy jackets and rain gear).

I took this to Orizaba this past winter. I traveled in them on the bus rides and hiked it them up to the summit. Overall great breathability and IT DOES NOT STINK. The zipper helps cool off when it's around 70-80 farenheit. I wore these everyday hiking and in my sleeping bag and I never stank and they don't itch. My buddies with Capilene complained about the itching in the crotch area and they smelt pretty bad. I think the wool is worth the extra cost. I also have the Wool 2 bottom and Wool 3 top and bottoms. If it gets super cold, I just layer all of them. Overall one of my favorite pieces of clothing.
