Icebreaker Women's Oasis Long Sleeve Crewe

rated 4.5 of 5 stars I own three of these, and they are the most useful pieces of outdoor clothing I've ever owned. Since I travel a lot and only take a carry-on, I find the Icebreaker Oasis Crewe comes off the mountain and dresses up fairly nicely for supper in the city. They never smell. They dry quickly and wash beautifully. I own three Crewe shirts in black, black, and fuchsia. Although the black ones are more versatile, I love the bright pink colour. If you like your shirts loose, take a size larger. They do occasionally… Full review

Icebreaker Men's Everyday Long Sleeve Crewe

rated 5 of 5 stars I would fill my closet with these shirts!! I've had this shirt for a few months now. I went on a two-week road trip Quebec-Colorado-Grand Canyon-Vegas and all the way back, and had this shirt for most of the time and skied with it. Came back and nobody could've said so by looking at it or smelling it. I am 6' - 175 lbs and took the XL so I could wear it with a looser fit, which also permits me to wear another tighter layer of merino underneath when really cold. So instead of packing 5-6 T-shirts,… Full review

Patagonia Men's Capilene Daily T-Shirt

rated 4 of 5 stars Dries fast, inexpensive and comfortable... This is Patagonia's Daily T-Shirt, advertised as being a regular cut so you won't look out of place in town. It's made out of the same quick drying Capilene polyester as the discontinued Capilene 1 Silkweight T-Shirt, with the same Polygiene odor control, but it comes in more "normal" colors. Also listed among its features are gusseted underarms (I don't know what that means) and 50+ sun protection. The material is good stuff, it's more abrasion resistant… Full review

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
