I bought this product to put under the Marmot Super Hero Jacket for snowshoeing. I'm 5'9" weigh 175 and wear a 41" suit jacket. The medium fits me great. I like the high ne…

This certainly is one of the best! I brought my cap 3 zip neck with me on the JMT as my baselayer! It was great. It kept me warm and was still very breathable. I really ha…

I have multiple capilene half zips that wear to work as well hiking. There's lot of different weights of capilene, so check out a couple versions. I like the lighter capilen…

I've been using this as my main baselayer. My normal set-up is this Cap 2, then an Arcteryx Strato jacket then a shell. This is for skiing and riding and snowshoeing in temps…

I wear my Capilene 2's everywhere! Both the tops and bottoms! They are the near perfect base layer. The only gripe I have against them is the infamous synthetic stink, but thi…

I have read the reviews of Patagonia base-layers and saw the great price on Moosejaw so I thought I would give it a shot. I did not realize how ridiculous I had been waiting…

I am a big fan of Cap 3s as my go to base layer in cold conditions. Also great just around the house on its own during winter. I normally wear XL (6'1"/200lbs) but this one…

Nota bene: Merino is costly and demands an investment, so I bought the Merino 2 on a ridiculous sale. That said, if you're willing to pay up, this will pay off. The merino/pol…

This is my 4th icebreaker shirt and it certainly hasn't let me down. A comfy slim but not quite spandex fit that goes well under everything from dress shirts to ski parkas.…

It was my first Icebreaker garment. They advertise on the odor free characteristic of merino wool, but I wanted to know by myself. I wore it for 2 weeks day and night... and b…

Love it under another layer of icebreaker. Wish my parents were Merino sheep no offense ma and pa so I would never run out of this product. Giving plasma every week to be a…

I love this shirt and the graphics, it is the lighter Capilene so it breathes even better but the fricken collar is fixed so it doesn't stretch at all, what the crap were they…

I run in this shirt all the time. It breathes well and is the perfect summer shirt for those 100+ days in the Texas summer. I highly recommend this shirt to anyone who lives i…

when you first look at this shirt it is surprising because you can see through it (unlike the capilene 3 shirt) which made me wonder how it could possibly be warmer than that…

The shirt is extremely light weight, feels great to wear, and I've found that it keeps me warm on some pretty cold (15 F) early morning walks. I bought it in xl since it said…

High quality. Very light, but kept me warm with through winter. On par with Cap 3, but softer and more comfortable…

This is another excellent piece of undergear from Patagonia. This undershirt is a slim fit, so if you want a loose fitting shirt, this isn't for you. The fabric is light and w…

Great product. A little pricey but I much prefer the wool over the synthetic baselayers. Well worth the price.…

I bought this along with the Capilene 2 Bottoms. My initial thought when buying was it might be heavy because I own Merino wool sweaters. I was dead wrong. This shirt is feath…

I never leave home without it. It is packable, quickdrying, and odor-defying. I've found the wool to be comfortable. The garment keeps it's shape very well as others have accl…

I have quite a few icebreakers, but this one does not top the list. It isn't as soft as the others, and I prefer the ones that zip down lower. It's an icebreaker, so it's good…

This shirt is ok, but I prefer the the higher weight shirts. Plus, the zip on this is far less functional than the 3/4 zips available on some of their other products.…
