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

Voormi Women's Thermal ll Baselayer Top

rated 5 of 5 stars Well worth the investment...this brand is amazing! This is one of the most comfortable performance tops I have owned. It's lightweight but warm...perfect for every season. The fit is amazing and very flattering. The fabric is wool, but not uncomfortable itchy. Great for layering or wearing on its own. Well worth the investment! Full review

ExOfficio Give-N-Go Boxer

rated 4 of 5 stars The ExOfficio Give-N-Go Boxer is an excellent choice for activities in hot, humid weather. The technical fabric wicks away moisture, helping you feel cooler, and dries quicker than cotton underwear so you're not left with damp, sticky boxers at your destination. They can be hand washed, and dry quickly so you really can get by with just two pairs. I'm slowly but surely getting around to replacing all my old-school clothing for warm-weather outdoor activities with modern, technical gear—no more… Full review

Patagonia Men's Capilene Lightweight Bottoms

rated 4.5 of 5 stars Go-to sleeping bottom. These are my go-to sleeping bottoms.  They're light enough to wear in the summer, provide a good base layer for the winter, and are more comfortable than laying directly on nylon or whatever. I've never gotten them wet but assume they would dry fast. They fit well, and have a functional fly. One extra chilly day I hiked most of the morning in them before I noticed the micro grid pattern on the inside was causing chafing. Wouldn't recommend putting miles in with these. Great… Full review
