5’11” 200 lbs size L fits great. I’ve been on the fence about these u set wear for a couple years now. Never saw them in person but finally purchased a pair and wow are the awesome. I will be getting more in the future. Lightweight and great fit. Might be the most comfortable pair of underwear I’ve ever owned. Wore them on a late season rifle hunt in Montana. They performed great.

Super comfortable and really warm for how thin they are. They don’t bunch up and that’s one of my biggest things is bunching and it doesn’t bunch at all

The best for warmth, durability. Worn over regular underwear with Smart Wool long socks gives greater flexibility bending at the knees instead of wearing long underwear. Got two last year and three more this year.

They are very comfortable except for the waistband, which is too narrow for me.

Don’t believe all the bad reviews. These are the best boxers on the market. I’ve got quiet a few pairs. Here’s the truth-

Do they last forever? No, but they last about a year of hard use.

I use these on field exercises and have taken them on many long rucks. No chafing, no riding up. They dry quickly.

You forget they’re on. It’s like a second skin. Just buy them, it’s worth every penny

Don't mean to cut anyone down, but I read the comments and was a little concerned, because I ordered them and then read reviews, but I must say. Blessed to not have experienced the problems states in the other comments. I have pretty big thighs and butt and have no issues with riding up at all. I washed them according to the tag and they fit nice and snug, but gives plenty of room up front for the goods. I hight recommend and must say I will buy many more.

I have had this product for less than a year and the upper, inside thighs have deteriorated to nearly nothing. Obviously, that area gets a lot of friction but my issue is that all my ordinary boxers that I also use for hiking/hunting have never had this happen. I contacted Sitka about it and they said it was due to natural wear and tear and would not replace it. My problem is that I could spend a quarter of the price and get something that last much longer.

The boxers are lightweight and comfortable, but a bit long for my liking. I love the feel, but would prefer them to be about 3" shorter in the legs. That's just my personal preference though. I bought these as everyday boxers to see how they worked out. Overall, they work, but just aren't my preferred fit. Wish Sitka had something like more of a boxer brief similar to what First Lite offers.

If you have big legs and a big butt, you won’t enjoy bending over, taking a knee, and sitting. They are tight around the legs and when you sit, they ride up.

Just got a new pair of these and love the fit. But after the first day of wearing them I have a 1/2 inch hole in one of the seams. comfortable but not sure of the quality of construction.

Fair, decided to give these a try but they are not for me. Fit is a bit loose and Sitka tag attached to back of waste band is very rough and caused irritation to my lower back. Cutting my losses at 1 pair. Material is very soft and appear to be well made. Also, a wider waste band would help.

Merino is amazing, from it’s ability to regulate body temp to it’s ability to keep odor at bay on multi-day backcountry expeditions. These boxers are incredible, a standard in my daily use and a must have for those early season elk hunts when temps can reach triple digits. Fit is exceptional, free flowing and unrestrictive. You can hardly tell you’re wearing them.

So I’m diving into Sitka after using several other hunting companies clothing. These are mostly great. What I think could be improved is that the leg cuff is comfortably snug when first put on but slightly relaxes overnight and is a little loose. Also, I dislike that everyone including Sitka is using cheap screenprinting for their logos! Comes off rather quickly and looks bad and a hassle! Some companies used to embroider their logos and for the cost of these garments I think they still should be or see a small logo patch on!

I’m a senior DT Instructor at FLETC and I’m pretty ruff on gear. I just bought 5 pair of these. Being a sceptic of gear hype, I put these to the test. Wore them all day and on a 5 hour coyote hunt in south ga in sept. Hot!!!! Then wore them the all next day putting in drain lines, Hot. They dry so quick and no smell. Was worried about them stretching out and they didn’t. Very nice!!!! I will be buying more. Thank you
