prAna Sophia Bra Top

rated 5 of 5 stars This bra does a nice "lift and separate." The plunging neckline looks great for me, which isn't usually a flattering style on my figure. I can't wear regular bras, only sports bras, and this is comfortable, supportive, AND looks great! I'm excited to wear some favorite dresses and not worry about my bra and the neckline. Full review

ExOfficio Give-N-Go Boxer Brief

rated 5 of 5 stars 6-star underwear! Would give six stars if I could. Have owned two pairs for about five years now. Initially purchased for treks to avoid the dreaded chafing. They are now used for any athletic venture. Quality: Two pair that have lasted five years, that alone is impressive. Material is kind on the skin, stretches well, but stays on the body.   Comfort: Have worn on 15-mile hikes, lots of sweating and ZERO chafing. They wick moisture amazingly and keep their form after a long day. Breathable: No… 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

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

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

MyPakage Pro Series 2-in-1

rated 5 of 5 stars Pro series long underwear and athletic shorts in one package. The unique MyPakage 3 dimensional pouch protects your precious parts. Unless you have worn MyPakage underwear, you are really missing a great experience. Utilizing their 3-dimensional keyhole technology pouch that surrounds your package, they give you the best feeling underwear on the planet. There is no more adjusting your package because the pouch keeps everything nicely tucked away and not in constant contact with your legs. Forget… 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

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
