Someone give me a qrd on underwear fabrics.

Someone give me a qrd on underwear fabrics. Am thinking of getting these, but I wanna know what is best for someone who is extra sweaty like me. Polyester stinks like absolute ass so badly that it’s made me wary of all synthetic fibers, but I’m willing to listen. I’ve read merino wool is considered the best for comfort and temperature but that it suffers from low durability, so a blend with synthetics would be advisable. What synthetic fiber will provide the needed durability without being garbage the way polyester is, and how much percentage should be the maximum? Also, should a distinction between made for underwear used for the gym and underwear used for everywhere else?

    this is marketing fluff from smartwool and others. ive worn 100% merino underwear for years and years from a small company in australia (theyre called Wundies lol if you are interested) and havent had any concerns with wear. wool blends are only useful for work-wear type pants imo where you will otherwise blow out the knees.

      Will check Wundies out anon thanks. Do you work out or have a physically demanding job? Idk if you actually live in Australia, but I assume it gets hot as hell there. Do you sweat very much? I’ve had cotton underwear that gets sopping wet and polyester underwear that smells like garlic onion ammonia after a few wears, regardless of washing; hate them both. Will 100% merino not deform and stretch out if used for heavy physical activity? You mention marketing fluff, but Leddit also seems to generally agree on 100% being comparatively fragile, and I doubt EVERYONE there is a bot.

        yeah, i was farming for a while and spend all of my free time galomphing outside in the cold and rain or sweating like a pig in the summer heat. tbh youd probably wear them out faster sitting on your ass in a desk job from the friction of the office chair. the marketing schlock about wool handling sweat/wetness better is true. they dont stink, and are temperature regulating. so regardless whether they get wet from sweat or from rain or whatever it seems to compensate. anyway i havent found any of them have blown out from overuse or whatever. wool sweaters will do that because of the looser weave. OH another thing you can put the 100% merino underwear in the dryer without it shrinking. i was being all careful about it and washing with delicate detergents and all, air drying on a line and then mistakenly ran a pair through the dryer and nothing happened. so ive gotten lazy and started drying all of them with heat and theyre still the same as always. i dunno man, honestly i would trust the opinions of LULZners before redditors any day. the people on /out/ know a lot about this stuff too, you might have better luck there than /fashion/. anyway good luck

          Fuark then I guess I’ll get a collection of office/work underwear and use the 100% merino for everything else including gym.
          >/out/
          Never been on the board so I wonder if I’ll get sent home for not being an outdoorsman or having those specific needs.

      Going to look at w undies…but have you checked out any other merino wool underwear companies liked art wool or icebreaker. Just wondering how they rank

        i just skipped them all since they were blends and i thought id find out for myself how durable 100 percent wool really is and was shocked it didnt fall apart in seconds like plebbit said so. i think the common experience is with "100% merino TM" straight from china that is made of who knows what probably recycled wool for all we know so of course its bound to be shit. get the real deal from aus mate. the exchange rate is good even to canadian dollars since aud is worth less lol

    gap breathe boxer briefs are the best i’ve ever worn, don’t strangle you and the cotton is very soft

      >74% polyester
      I can’t wear these. I’ve tried underwear with less polyester than this and the smell is disgusting and very noticeable.

    >polyester
    You seem to be aware but other anons might not, so I believe a PSA is appropiate.
    Whatever you do bros, NEVER wear polyester underwear. They’re extremely bad for male virility and are shown in certain studies to lower sperm quality to practically infertile levels. Never ever put polyester on your balls.
    Other things to look out for are underwear that’s too warm (long trousers shoul be avoided until absolutely necessary) and too tight (tightness->heat->reduced function of testicles). Underwear should be loose fitting and made with 100% natural materials.

        >https://pubmed.ncbi.nlm.nih.gov/1623716/
        This one’s from 1992 and it explores a polyester sling as a method of male contraception. In about 5 months of wearing it, all men became azoospermic (no sperm in semen). Testicle size and sex hormone production were significantly lowered. These levels and the quality of sperm returned to normal after they stopped wearing the sling, but it still took about 5 months to get to normal. The researchers speculated that polyester does this by not only hecking with the cooling of the testes, but also by generating an electrostatic field
        >https://pubmed.ncbi.nlm.nih.gov/30102388/
        Not directly related to polyester, but in this study it was found that men who reported wearing boxers had better sperm quality. It seems to also indicate that heat management is important for testicle function, which polyester is bad at.

          Tha is anon. Planning on buying one each of https://www.smartwool.com/shop/mens-merino-boxer-brief-sw016997?variationId=K11 and https://www.icebreaker.com/en-us/mens-baselayers/merino-175-everyday-thermal-boxers-with-fly/104485U2.html?dwvar_104485U2_color=001&dwvar_104485U2_size=M&dwvar_104485U2_US=in_line to test them. Former is more aesthetic and seems like it may have more space for cock and balls, plus seems more elastic and is 88% wool, while the latter is 100%. How bad would 12% nylon be? Is it all or nothing? Will report back btw.

            Jesus, those prices. For that much money I would really hope they are durable. But hey, anything can be mended. And with wool you could wear them every other day for a week without washing. You would only really need 3 pairs to rotate.

          • Anonymous says:

            I know, but the stench is honestly so revolting that I’m willing to spend $40 a pair to fix it. The pricing is the main reason I want to know if they’re good for the gym though, or if they’ll fall apart too quickly from that kind of treatment.

            I don’t know about polyester vs nylon, but wool is better than any synthetic fiber for sweaty areas like undergarments and socks.

            Yeah, that’s why I’d rather one of the earlier options like the ones I posted

            I prefer these to the ones you linked: https://www.icebreaker.com/en-us/mens-underwear/merino-anatomica-boxers/103029U2.html?dwvar_103029U2_color=A84&dwvar_103029U2_US=in_line

            They seem like they would fit better on big thigh guys like me. I hate when boxers get all bunched up in my crotch when they are too short.

            So is it exclusively the length that makes you pick these? What do you think about the 100% merino of the one I linked vs the 83% merino blend of yours?

          • Anonymous says:

            Oh it is 83% wool, with 5% elastane. That is perfect for me, for underwear. The elastane will make them super comfy. And yeah, length and fit are the biggest factors for liking those over the 100% wool ones. Plus the elastane.

          • Anonymous says:

            Yes, and 12% elastane as well. I’m assuming you’ve had no odor problems with these though, the way you’re talking about them. Have you ever owned/used a pair of the 100% merino ones?

    • Anonymous says:

      I like the designs of certain underwear, but they’re always a blend. These Wool & Prince ones https://woolandprince.com/products/boxer-briefs-ochre look fantastic, with the color and the unbranded waist, but they’re a 75% merino, 21% nylon, 4% spandex blend. How would this fair? Would I still be hurting my reproductive health with this and should look for 100% merino ONLY, or is it acceptable?

      persists; I sweat a ton and the cotton just mops it up and I have that wetness up against my skin for extended periods.
