Recent Base Layer Top Reviews

MEC T3 Zip-T

rated 4.5 of 5 stars Excellent thermal base-layer top. This review is for the standard (Synthetic) T3 Zip-T, not the more expensive Merino Wool version. The photo shows the 2-tone Eclipse Heather/Coal colouration. The T3 is the thickest in MEC's own line of thermal base layers. The T2 and T1 are each lighter and thinner than the previous. The Zip-T model of the shirt has a half-length zipper (as the name implies) and a tall collar when fully zipped, almost like a turtle-neck. No pockets; no cinches or draw cords; no… Full review

Helly Hansen LIFA Merino 1/2 Zip

rated 4.5 of 5 stars An excellent base layer choice from a company that understands cold and wet weather. The HH LIFA Merino 2-layer construction keeps you warm and dry in all kinds of conditions, and feels great when wearing it. Watch out for the “athletic” fit when purchasing, but if you get the right fit this base layer will keep you comfortable in rain, sleet, and snow well below freezing. Note: This is a companion review along with the Helly Hansen LIFA Merino Pant. Product Description Helly Hansen (HH) LIFA… Full review

Fjallraven Bergtagen Woolmesh Sweater

rated 5 of 5 stars The Fjallraven Bergtagen Woolmesh Sweater is a base layer top that utilizes wool in three different weaves to maximize heat retention in key areas (chest, back) and breathability in others (stomach, underarms). It’s a total home run of execution and since I received this top for testing I have worn nothing else. It’s exceptionally well tailored, durable, doesn’t stink on multi-day trips, and you’ll have no fear around a fire. The only possible negatives are more inherent to wool, than this… Full review

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
