Recent Base Layer Top Reviews

Woolx Everyday Long Sleeve Crew 230 Midweight

rated 5 of 5 stars The WoolX men's Everyday Long Sleeve Crew, 230 Midweight Top (X506-302) has become, without any doubt, my favorite base layer top. I wear it frequently, pretty much year round, as a stand-alone layer, or beneath other layers and outerwear. It is incredibly comfortable, has great warmth and wicking capability, and has held up well for over a year of use and washings. Definitely recommend investing in this top!                                                    … Full review

Craft Men's Active Extreme 2.0 CN LS Top

rated 4.5 of 5 stars An awesome baselayer from Craft. The Active Extreme 2.0 CN LS is NOT a thermal baselayer even though according to the company's graph it's best suited for elite athletes doing high intensity activities in temps hovering at -10° Celsius... ...ooorr just any other regular dude that sweats doing some very light backpacking @16-17° Celsius and 77% humidity in Crete (lol).It feels warm when in sunlight due to the black color, but when in shade the temp drops instantly! I mean this thing really cools… Full review

Coldpruf Platinum II Crew

rated 5 of 5 stars ColdPruf has better quality materials (not cotton) than the old stuff I have, and the fit is much better. There are excellent sizing charts and sizes for tall people, like myself. The fit is great. I could comfortably play sports or other activities in the Platinum II without any range of motion restrictions. It is tight enough fitting for a base layer (the modern name for long underwear), but not too tight. Recommended for active people in cold climates. As a member of another website, I get products… Full review

Icebreaker Oasis Crewe S/S

rated 0.5 of 5 stars Very expensive crap. I am in New Zealand where Icebreaker comes from and this brand has gone downhill in the last year or so. The quality is not what it used to be and is mostly no longer 100% pure Merino wool as their general advertising would have us believe, instead having other artificial fiber incorporated into the yarn I am informed. At the beginning of winter I bought three Icebreaker items. A scarf, a sweater, and a base layer. The first two were returned to the retailer as they were not… Full review

Icebreaker Oasis Crewe S/S

rated 5 of 5 stars This 100% merino wool t shirt is great for most outdoor pursuits and workouts. 200 weight merino is a bit heavier weight than the "ultralight" wool t's and has benefits, namely more warmth and durability. The ability to wear while damp, wick moisture, and stay warm is wonderful. Smooth finish is not itchy. This is really a tale of two t-shirts. In 2010, I purchased Icebreaker's Hopper Lite t shirt and still wear it today. That model was later discontinued. A couple of years ago, I searched for and… Full review

Beyond Clothing Aether Crew

rated 5 of 5 stars A great short sleeve base layer shirt that can be used on its own for hiking or under other items if the weather is colder. The shirt is super soft and extremely comfortable with ridges that help wick the sweat away from your body and keep you cool even during strenuous exercise. I would definitely recommend it for anyone who will be doing heavy outdoor activity and wants something lightweight and breathable. I got the Aether Crew base layer shirt as a reviewer and got to test it out on a recent… Full review

U.S. Military Gen III, Level 2 ECWCS Top

rated 5 of 5 stars U.S. made Polartec Power Grid fleece top for $20. Compare to the $100 Patagonia R1 which is now made overseas. I find myself wearing the level 2 grid fleece top (aka waffle top) more than any other garment when playing outdoors. Here's why: Ultra breathable Great wicking properties Warm, even as an outer layer Versatile: can be used effectively as a base, mid, or outer layer Thumb holes to facilitate the donning of other layers Half zip for venting Even if I do sweat while wearing this, the impressive… Full review

Sherpa Adventure Gear Men's Baans Tech Quarter Zip

rated 4.5 of 5 stars Used this for basecamp warmth after hiking 7 to 9 hours in the fall Maine weather. After hiking all day relied on this to stay warm while setting up campsite and in the cool fall Maine mornings to stay warm while breaking down. Keeps you extremely warm and comfortable during these critical times. This pullover fits great and is extremely comfortable after a long day of hard hiking. Provides essential warmth in the cool fall Maine weather after a great day's hiking, or in the early cold fall mornings. Full review

Kora Shola 230 Crew

rated 5 of 5 stars Warm, soft, well-fitting, comfortable even in warmer temperatures. It's been years since I've lived in a climate cold enough for a base layer. Actually it's been 13 years... I remember them as itchy, uncomfortable, and most of the time I would rather freeze than wear them. I definitely have needed them since returning, and I decided to bite the bullet and pick up a set for the upcoming winter, which the Farmer's Almanac says will be one of the coldest winters in some time. I typically would not… Full review
