Recent Base Layer Reviews

Coldpruf Platinum II Pant

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. Recommend for active people in cold weather. As a member of another website, I get products… Full review

ExOfficio Give-N-Go Boxer Brief

rated 1 of 5 stars The fabric makes the genitals sweat and smell. The fabric seems okay, but the genitals sweat and now smell.  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

Minus33 Acadian Lightweight Boxer Brief

rated 5 of 5 stars Worn for seven days straight on a canoe trip in Northern Maine during variable weather in august!!! Amazing!!! We outdoor industry dedicatees remember the Ex Officio campaign claiming that their underwear could take you around the world and beyond. That their undies are so great that with a simple weekly sink washing whenever you happen into a hostel your drawers will smell of roses and no crotch rot will ever inhibit your adventuring. As is my way, I put them to the test.  They were good, I’ll… 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

Airblaster Men's Ninja Suit

rated 4.5 of 5 stars Looking for a "onesie?" The Airblaster Ninja One-Piece Suit offers all I need for a full coverage, draft free, mid-weight base layer...without the bulk! As is often the case for me (being on a fixed income) I enter review contests to win gear that I need (but can't afford) for my passionate pursuits. Winning another site's campground review contest, I garnered a coveted gift certificate to Airblaster (myairblaster.com). I must admit, the gift certificate was substantial and I was no less grateful...but… Full review

ExOfficio Sol Cool Boxer Brief

rated 4 of 5 stars Jade infused fabric pulls moisture from your body for a cool sensation. Slim fit does not bunch up. I was sent a pair of ExOfficio Sol Cool boxer briefs in late January for testing and review. I actually tried to wear them during the winter but found that they were just too cool for comfort at that time of the year. Once things started to warm up I gave them a thorough workout. Comprised of 52% Cotton, 42% Nylon, 6% Spandex, the nylon has been infused with Jade, yes, Jade the rock. Apparently,… Full review
