Recent Base Layer Top Reviews

Ridge Merino Inversion Heavyweight Crew

rated 5 of 5 stars A merino wool baselayer that is soft and warm. Perfect for cold-weather activities of all kinds. Fit and Comfort: Finally, a baselayer top that has a little extra length in the sleeves and torso and stays in place, no matter the activity. I’ve worn several merino products over the years and this is as comfortable as any that I’ve worn with a soft-to-the-skin and no-itch feeling. This top fits close but not restrictively tight to the body. The length of the torso and arms are both generous, meaning… Full review

Toad&Co Pacer Slim Long Sleeve Quarter Zip

rated 3.5 of 5 stars A versatile garment from a philanthropically-minded company that strikes a compromise between backcountry base layer and in-town casual wear. With grime-concealing colors and a poly-wool blend, the Pacer Quarter Zip is a thermoregulating, moisture-wicking, low-odor option for travelers with limited wardrobe space and for anyone who doesn't mind giving up some performance or style for a garment that offers a viable trail-to-town option. A Trail-to-Town Quarter Zip The Toad & Co. Pacer Slim Long… Full review

Helly Hansen Women's HH Wool LS Crew

rated 3.5 of 5 stars Sturdy, warm, and straightforward. This is not the most comfortable wool base layer out there, but it performs beautifully in terms of fit, warmth, and durability. This top is well made and will keep you warm. No bells, no whistles. Fit & Comfort - Fit in arms, shoulders, and torso is true to size, keeping in mind that the desired fit of this top is very snug. I'd recommend trying it on before buying if you have concerns about the sizing. The wool was fine on my skin, but other backpackers found… Full review

Smartwool Men's NTS Mid 250 Hoody

rated 5 of 5 stars One of my favorite pieces of clothing. Perfect balance of warmth, comfort, and style. This is one of my favorite pieces of clothing. I wear it all the time. It fits just right. Not too tight, not too loose. Feels comfortable against the skin and breathes well.  I'm 6'2" 225 lbs. and the XL was perfect. It is plenty long in the sleeves and torso. Stretchy, but not constricting. I have used it both as a base layer and as a standalone top in milder weather. It layers well. The hood is a little loose,… Full review

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
