Icebreaker Men's Everyday Long Sleeve Crewe

rated 5 of 5 stars A superb, comfortable baselayer for cool weather activities. I started wearing Merino baselayers back in 2003, when they first seemed to be hitting the market. In those days, it was Smartwool, and not much else. Most of the tops I purchased those many years ago, are now in tatters, so it was time to replace. Having had good recent success with Icebreaker, I found this shirt on sale, and took the bait. I have found Icebreaker's fit to be slightly on the small side, so even though I usually wear XL… Full review

Patagonia Men's Capilene 1 Silkweight T-Shirt

rated 4 of 5 stars Good, solid base layer. This is a solid T-shirt. The material has a slight sheen to it, is a bit stretchy and very comfortable. It wicks and dries very quickly. I bought mine in black about 6 months ago. It's been washed about 10 times and the seams and stitching still look great. I hike in just this shirt during the day and haven't had any problems with snares from gear or branches, so I'd say it's durable. It still smells fine, and I think whatever odor guard Patagonia is using works well. It's… Full review

Patagonia Men's Capilene 2 Lightweight Zip-Neck

rated 5 of 5 stars Easy care material that can be washed in a sink as well as in a washing machine. Lightweight and durable. My most durable layering piece. I have tried many other alternatives for active heat retention base layers, and always come back to this piece. Deals well with odor, the rubbing of straps through clothing, and drys quickly. Freedom of movement is incorporated in the design. Capilene has worked very well for me. Try a garment on your next adventure.  Full review

Patagonia Men's Capilene 1 Silkweight Crew

rated 4 of 5 stars Comfortable and light with powerful wicking properties, this shirt works well as a base layer and even better as a standalone cooling shirt. Great for those who need to stay dry in cold weather and those who would enjoy the evaporative cooling effect when hot. Fit & Comfort Made from a soft and resiliently stretchy 94% polyester and 6% spandex, the Capilene 1 material feels great against the skin, which is important for a base layer. The sized large I purchased was listed as being a "slim fit"… Full review

Patagonia Men's Capilene 2 Lightweight Zip-Neck

rated 4.5 of 5 stars Excellent baselayer shirt with the durability to withstand years of hard use. The Patagonia Capilene 2 lightweight Zip Neck makes the perfect baselayer for hiking, climbing, and all other outdoor pursuits. So far, I have used it on a three-week backpacking trip in Arizona, a two-week canoeing trip on the Rio Grande, a five-day hike in the High Sierras, and countless day hikes and overnighters all over the country. One of my favorite things about this shirt is its ability to manage sweat effectively,… Full review

Patagonia Men's Merino Air Hoody

rated 5 of 5 stars Every base layer needs a hood. I could hardly tell it was there since it stretches and breathes so well. The Merino Air Hoody, made from Merino wool blended with synthetic Capilene, is easily one of the best products I have reviewed so far. I have often repeated the advice, "it's no good with no hood." Hats are okay but they get lost (kids take them) and make your head itch. Most of my jackets have hoods, my insulating layers have hoods, if I could buy socks with a hood, I'd do it. That is why I… Full review

Icebreaker Bodyfit 260 Olympia Crewe

rated 4.5 of 5 stars Great product, warm, odor free, and no wool itch from the super fine merino. Their sizing runs on the small side, and you need to be careful of moths! I love my merino undershirts enough that I own four. I have two Icebreaker brand and two not, and the Icebreaker ones have proven more hardy that the others. I have worn this snowboarding, on fieldwork for a couple of weeks at a time, and under dressy clothes in cold climates and it does the job amiably. My biggest gripe is that their sizing runs… Full review

Icebreaker Women's 260 Midweight Tech Top

rated 5 of 5 stars Icebreaker rules! Looks great, non odor, and great temperature regulation. After discovering Icebreaker products, I tossed all of my synthetic layers. I use the 260 as a mid weight layer and keep it in my pack to toss on when stating still in moderately cool weather. Over a 150 tank and under the 320 full zip, I am good for temps down to 20°F. I love the way it resists odor and maintains insulation properties even when wet, and Icebreaker's designs always look good too! Full review

Patagonia Men's Merino 3 Midweight Hoody

rated 5 of 5 stars Encapsulating warmth, anti-stink, relatively quick drying, wicking, optional thumb loops, light weight, and recently on sale! Is that possible? One top to rule them all. Fit for me is spot on. Deep chest zip is aah-so-perfect, extra long arms, breathes and adjusts to temperature better than anything, layers perfectly, because of merino/Capilene fusion. This now has better abrasion resistance and drying time. From 55 degrees and below this is the ultimate upper body single item apparel. I now own… Full review
