Merino.tech 100% Merino Wool Underwear Men - Mens Boxer Shorts 1-2 pack

Firstly, I accidentally bought one size too large. Unfortunately, because of that, they feel a bit odd and tend to bunch up at the back. That said, I can’t overstate how long these can be worn without developing any noticeable smell. For me, that area of the body usually starts to smell heavily after just a single day in regular cotton briefs. With these, however, there is virtually no smell at all. I’ve worn them for up to three days, and even then, you’d have to really try to notice any odour and it’s still not bad. For hiking or extended off grid trips, these are excellent. In those situations, I do use wet wipes twice daily to stay fresh. However, my three day test was done without any freshening up at all. Bloody amazing. I’d estimate you could wear these for well over seven days before they smell as much as a cotton pair would after just one day. I don’t use them with the intention of being unhygienic, but when you’re trying to carry more water or food and space is limited, having just two pairs of these could easily cover you for extended periods in the wild. I’m genuinely amazed at how odour resistant they are. I also own merino wool socks and thermals, and they perform just as well in terms of odour control. I’m now looking forward to replacing more of my hiking gear with merino wool. The only downside is the cost t-shirts are particularly expensive for what they are, often close to £40 each.

Good quality, fit well, comfortable and wash well.

I was looking for merino underwear for a while, when I finally found those. First impression was very good. I like them. They are light and very comfortable, fit perfectly and most importantly, provide very good ventilation, removing sweat promptly. Exactly what I wanted. I am completely satisfied with their performance. However... their biggest drawback is durability or the lack of it. I got two pairs and both did not even last a year. I feel like, for the price, they should have lasted much longer. So what did I do? I ordered another two pairs ;] I noticed that the new ones differ slightly from the old ones, so hopefully they will last longer

Very comfortable and long lasting compared to competition. This is after using them for over 6 months. Highly recommend!

I just used these to hike up a steep hill, camp on the top, hike back down, and sit around at home in them all day. I took them off and let them air for 20 minutes and smelled them and they still smelled incredibly fresh. Without going into too much detail, I get quite sweaty even sitting around let alone climbing a hill. If I had worn cotton ones they'd be soaking wet by now and probably transferring moisture onto seats when I sit down. Synthetic/spandex type ones may well be dryer but would be smelly. By comparison I notice the wool is slightly damp but crucially still super warm, and as I say not smelly at all. It really is a game changer.

Worn on two cycles and already ripped at crotch. Do not buy.

They lasted me 4 heavy use months, now there is holes in them both by the buttocks where I sit on my saddle

Great underwear. Would and have bought again.

Used 3 pairs on 10 day trek to Everest base camp. Where the weight you bring matters. No chafing and no odor. Couldn't ask for anything more.

Would absolutely be 5 stars if they weren't build like a cheap castle (as in, there's no Ballroom.) Very flat front. Fine if you like the compression sensation, I suppose, or giving anyone who might catch a look a VERY clear outline of the equipment you were born with.

Love this underwear. I agree with some of the other purchasers when they note the waist band loses some of its elasticity but I actually don't mind that. It isn't so bad that they are falling off, just a bit more relaxed around the waist. I have logged a lot of hours hiking in these and they keep me fresh and are comfortable as well as functional. I am going to be taking these with me as I walk the Camino in June which speaks to how much I like them.

6 months of ownership and have holes already. Seams and quality of material are thin and poorly made. Does not compare to the other brands.

Exceptional quality at a very reasonable price. The t-shirts are comfortable and make a great base layer.
