The Smartwool community is a collection of people who believe that time outside is valuable, restorative, and essential for everyone.When Smartwool started making socks back in 1994, their founders simply wanted to be able to ski longer without getting cold toes.That’s when they discovered the benefits of Merino wool as a performance fabric. It was soft (softer than any wool they had every felt), moisture-wicking, thermoregulating (warm when it’s cold, and cool when it’s warm), sustainable, and odor-neutralizing- helping to keep feet dry, comfortable, and warm for longer than the synthetic socks they were wearing at the time. It worked so well, in fact, that Smartwool uses it in almost every single item they make.

Smartwool was the first outdoor company to make performance Merino wool ski socks- revolutionizing the category and forever changing the way outdoor enthusiasts viewed their feet.

Smartwool’s whole brand was built on the desire to be comfortable on outdoor adventures-we wanted to go farther and experience more. And that drive continues to fuel everything Smartwool does. From their Merino wool supply chain to the Smartwool advocacy program to how they design their socks and apparel, Smartwool exists to help you play, love, and laugh in the great outdoors as often as you would like.

    Bought these after seeing an online blog post about the best travel-ready underwear (i.e., you can wash 'em in the shower and they'll dry fast, plus they prevent as opposed to encourage chaffing).

    Pros:
    Very good for the road. Plus one star.
    Also, no chaffing and breathes well. Hence star number two.

    Cons:
    Fitting is almost an entire size smaller than advertised (at least judging by all the other brand underwear I've put on...) So, minus one star.
    Also, if you have anything like a belly (as opposed to chiseled abs or no figure at all), the overly wide waistband will curl up on you enough to affect your digestion. Looked cool until I put 'em on. Tried 'em out for three months, too. Couldn't lose enough belly in 3 months' time to not have the band curl up and corset me, so considering the cost of these babies, minus *two* stars.

    TL;DR --> If you're skinny and wanna pay $$ for underwear, these might work really well for you. If you're normal(ish), I'd pass.

    The price sucks, I know, but if you have the extra money, they're worth it. They are so much better than the cotton Fruit of the Loom boxer briefs I've been wearing my whole life. Those are thick and kinda scratchy. These are thin-ish, soft, they regulate temperature well, they're odor resistant, and they just feel good to wear, like comfy sweat pants, but for your genitals. The odor resistance thing is very real, too. On a recent trip to Europe, I had three pairs to last me two weeks, and it took them about three days to start smelling like my cotton underwear smells after one day. I have yet to see if they will last for more than a year or two, but I'm crossing my fingers.

    I'm 5'10, 150lbs, and I like a slightly tight fit on the thighs, so the mediums are perfect.

    Quickly became my favorite pair of underwear. Merino wool definitely is a wonder material though like others have said you'll have to watch out when drying them. Too much time in the dryer will cause some shrinkage though unlike some other reviewers, I never found it to be permanent or excessive. They say Merino wool should be air dried but with these I never found it necessary, if you don't like your underwear to have a snug fit then get a size up, they will be snug when you first out them on but stretch to fit pretty quickly in my experience. My only complaint is price. $45 for a single pair of underwear is a bit high and even though I like my pair very much, the price will likely keep me from ever getting any more of them. They're simply not THAT much better than a pair of hanes or something to warrant $45 a pair.

    It has been about a month or more now. I need to change. Everything alleged about wool underwear is true. Wool is great This boxer is great.

    Update: purchased these June ‘18 and now, April 1, ‘19 the crotch is threadbare.

    I took these to Coachella which as you can imagine, is the ultimate testing grounds. Honestly, I could have solely used just these all weekend and would have been fine. They're super comfy and breathable so airflow is perfect while you're in 100° weather and are dancing through the day. Definitely recommended!

    Love these! I took two extended trips in 2016 both of which involved a lot of hiking and walking and limited opportunities to do laundry. Many times over the years trips like these have resulted in painful chaffing in the groin area. Not so with the Smartwool Boxer Briefs. They are not cheap but they are highly effective. You can wear them day after day with no odor, no discomfort.

    This is the only pair of boxer briefs I’ve ever had that don’t ride up in the legs, and they don’t even feel particularly tight! I have muscular legs and wear form-fitting pants and jeans. These are far better than any other brand I’ve tried at the same price (Calvin Klein, Under Armor, etc.) I’m interested to see how they perform in hot weather, but right now I couldn’t be happier. Worth every penny.

    I replaced all of my underwear with these boxer briefs, and here's why:

    -great fit, plenty of room for the important bits
    -solid build, double stitched everywhere!
    -superior merino wool feels and performs amazingly
    -they keep me cool when working hard, and cozy when I'm relaxing
    -thick waistband doesn't fold or roll like other cheap brands

    Yes, they're expensive, but well worth the price to me and my active lifestyle. I know a piece of essential gear is worth its weight in gold, and these Smartwool boxer briefs are no different. I highly encourage you to buy at least one pair, and if it somehow doesn't convince you that you've been missing out on the life of luxury you deserve, Smartwool's professional customer support members are a delight to work with for returns/refunds. Thank you everyone at Smartwool for another piece of quality wear!

    Good product, nice fit and well made. I use this for a combination of climbing and when working outside on v.hot days-keeps the downstairs cool.
    4 star due to the rainbow waistband sometimes rolls.
    An expensive item but my research put these guys too and can see it's value- I have two pairs for exercise.
