Recent Base Layer Reviews

Terramar Men's Silk Pant

rated 2 of 5 stars Great pajamas, poor base layer. Thermasilk base layer from Terramar is not adequate for outdoor sports or any type of physical activity: It is far too weak and fragile. It is too thin to provide any warmth, and when wet, they feel cold. They will rip and shred if worn in an endurance sports or hard work setting. Also, they do not hold their shape. Hand-washing brings back their original shape, but they become limp after a couple of days out in the field. On the other hand, they make the best pajamas,… 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

Patagonia Men's Capilene 2 Lightweight Zip-Neck

rated 4.5 of 5 stars Super lightweight at 6.5 oz. Very quick dry. Super open breathability without giving up warmth. Great light, breathable, super quick dry base layer. Fits snug to body, but doesn't stick. Allows for easy layering without that cramped tight feeling. Don't leave home without it!!!! Full review

Terramar Mesh Pro Boxer Brief 6"

rated 5 of 5 stars Unbelievable! Great value and extremely comfortable! These Terramar High Performance Boxer Briefs were a lifesaver. Not only did they fit great, they were easy to wash, dried out fast, and provided plenty of support on those long day hikes. Did I mention they are less expensive than most of the other odor-eliminating briefs I came across as well? If you are looking for new briefs give these a shot. You will not be disappointed.

ExOfficio Give-N-Go Lacy Bikini

rated 5 of 5 stars This underwear is great for hiking, backpacking, travel, and everyday use. The material is soft, it wicks moisture and has a comfortable fit. It's hard to find women's underwear that stays comfortable through miles of backpacking, but the ExOfficio Give-N-Go Lacy Bikini brief does just that. The nylon/spandex blend has four-way stretch that provides good coverage without bunching up or chafing and feels soft to touch. The flat lacy band provides a feminine touch to a technical product, which is… Full review

Kora Shola 230 Zip

rated 4.5 of 5 stars Kora’s yak wool Shola 230 Zip base layer beats the itch of other wool. It provides a lot of warmth without a lot of weight or thickness. This zippered base layer top is constructed using Kora’s own Hima-Layer Original 230 yak wool fabric. All testing of the Kora Shola 230 base layer was done on the ski hill. I am very sensitive to lamb’s wool, and was pleasantly surprised when I first put the Kora zip base layer on. Immediately it became evident that not only is yak wool not itchy, it has… Full review

MyPakage Action Series Boxer Brief

rated 5 of 5 stars By isolating your package, MyPakage underwear is super comfortable. Wicking fabric keeps moisture at bay. MyPakage has an entirely new take on men’s underwear. The Keyhole Technology internal pouch surrounds the male private parts with fabric, providing both support and comfort. Below the Keyhole, MyPakage has installed a pucker panel which removes any seams that might cause discomfort or chafing. The Weekday series replaces the cotton used in most underwear with an exclusive fabric made of Modal… Full review

ExOfficio Give-N-Go Boxer

rated 3 of 5 stars They are OK, Duluth Trading is much better. I have a couple of pairs and wear them often, today in fact. However I also have a few pairs of Duluth Trading Buck Naked briefs. The Duluths are much more comfortable, don't ride up, and are my choice when hiking. I think the Duluths are a little cheaper also. The ExOfficio's were my first purchase and I wore them about a year before I tried the Duluths. Full review
