    The article makes a lot of mistakes, because I don’t think that the author actually cares about textiles at all.

    Cotton is not comparable to wool at all. Full stop. If you wear wool for technical reasons–like, because you want to stay warm–then you need to know that cotton will kill you, as will all cellulose fibers that aren’t treated to be hydrophobic. Petroleum-based fibers like polyesters, nylons, etc., do not wet the same way that cotton does, but also don’t keep you warm in the same way that wool will. Wool is the gold-standard for cold-weather outdoor apparel.

    Tencel–which is a type of rayon–is considerably weaker than cotton when it gets wet. The process for making rayon is usually–but not always–a very polluting open-loop system. There are closed-loop systems, but they weren’t in common use as of 2010.

    Leather is irreplaceable as a protective material. Synthetic leathers lack the abrasion resistance and/or heat resistance of leather. Compare a pair of high-quality leather boots to the highest quality non-leather boots; leather will last decades longer. So you can’t compare on a per unit basis; you need to compare them based on practical lifetime costs. In regards to certain protective apparel–such as motorcycle gear–textile jackets simply do not provide the same level of repeatable protection as leather. If you ride your bike on a track, you will be required to wear leather.

      My understanding was that there are three types of rayon. Or have I been had by Big Cellulose?

      • Viscose is the one that gets weaker when wet, and uses aggressive chemicals
      • Modal gets stronger when wet, but also aggressive chemicals
      • Tencel (brand name for lyocell) specifically refers to that closed loop process with less harsh solvents, and also gets stronger when wet

      If something just says “Rayon” you can probably assume it’s viscose. Tencel sellers want you to know it’s Tencel.

      Regardless, none of the above are good for warmth, so bad replacement for wool no matter which process they use. I do love my Tencel bedsheets though.

      The fake leather thing is real. It’s why you can reuse a leather jacket after a motorcycle crash, but not a textile one. Leather also slides better, and sliding gently to a stop after a motorcycle crash can really save you.

        Sliding is def. better than rolling!

        Oh, another thing: welding. I don’t think I’ve seen a synthetic material that works as well at protecting you from the combination of heat, slag, and abrasive materials as leather does.

          Can’t you / shouldn’t you be wearing a rain coat or outer shell if you think you might get wet?

          I get there are some situations where its impossible to keep underlayers dry, like if your on a boat or Backcountry camping, but for the majority of people and situations some layers of cotton or synthetic under a shell should be fine.

            perspiration. Sweat will sap heat just as fast as water if you’re wearing cotton

              Rule #1 of cold weather survival: You sweat, you die.

              Wool isn’t going to save you. Taking off layers will. If it’s raining, wool won’t protect you any more than cotton will because neither are water-resistant. Lol.

              So sad this needs to be spelled out for ya’ll, but the voting snowball effect has already taken hold.

              Now we have like 10+ who legitimately believe wool will save you in a cold, wet environment where cotton wouldn’t.

              Laughable.

                  So… can you quote anything from it that proves your point? Or do you just link to studies and have other people read them for you?

                    Sure, lazy ass.

                    wool fibers are able to accumulate the moisture (from sweat or small rain) fully in the central part (cortex) and simultaneously keep the hydrophobic surface shelves dry, thus offering relative high thermal resistance and dry (warm) contact feeling even with 30–40% moisture in the fabrics

                    thermal comfort properties of wool fibers and wool fabrics cannot be found in cotton and viscose fabrics, (Oglakcioglu and Marmarali 2010) where the deterioration of their thermal comfort properties with the increasing relative moisture is much stronger and quicker than in the studied woolen fabrics samples. Thus, even in case of wool and wool/PES fabrics subject to some antifelting treatment, like in our case, the thermal comfort properties of the investigated samples exhibited relatively slow decrease of their thermal resistance and relatively slow increase of their thermal contact feeling, when the relative moisture content increases. That is why the woolen fabrics belong to the most comfortable and valuable commercial textile products.

            If you’re outside in cold weather, yes, you should wear a shell layer. However, it’s not just water coming in from the outside, it’s sweat from your body. You can’t avoid sweating; it’s how your body regulates temperature. But compare, say, a polypropylene sports jersey to a cotton t-shirt on a hot day; the cotton gets wet with sweat, and then stays wet longer. In really cold weather, that’s bad. (And if you’ve ever gone snowshoeing, you know that you’ll work up a sweat fast.)

            There’s a lot of contradictory-seeming things happening, but it’s pretty easy to test results for yourself. Get comparable long underwear in both cotton and Merino wool, comparative outer garments in wool v. cotton (say, German or Swiss wool milsurp field pants and shirt v. heavy cotton duck pants and heavy cotton flannel shirt), go outside on a cold winter day and do the same activities wearing different fibers, and see which ends up feeling warmer.

            Yes, you should.

            The idea that wool will “keep you warm when it’s wet and cold” is such a crock of shit I’m surprised it’s getting upvoted like it does.

              Wool will keep you warmer than cotton when it’s wet and cold. As usual, shades of grey get lost in the discussion.

                “Warmer than cotton” is not the same as “warm” lol. That’s what I’m trying to get through the people who think that if it’s cold and wet enough cotton can’t protect you when wool can.

                That’s just malarkey.

          Bullshit, 100%.

          If it’s cold and wet enough that you’re going to freeze wearing cotton, you will also freeze wearing wool.

          Wool doesn’t repel water. Water passes right through it onto, guess what, you.

            It’s ok to not know something. You don’t have to share an opinion that has no basis.

            If you’ve ever done multi-day outside activities in the cold, you learn really quick to not wear cotton socks or under layers. Your sweat is what makes you cold because cotton will no longer provide a warm layer. Wool still has air pockets and will keep you warmer and may save your life or limbs.

            Are you going to be comfortable in wet wool? No, but you have a better chance of surviving and not getting frostbite.

              Identify the opinion or admit you don’t know what an opinion is.

              These are the people who think wool will keep you from freezing in the wet and cold while cotton will not.

              All I can say is, lol. Make your own decisions and don’t let strangers on the internet put your life at risk.

              I’m not going to argue with them anymore because I’ve come across their type before and no matter what, they will believe contrarian bullshit and fight tooth and nail to defend it.

                  Do you have wool? Place it over a cup and then pour water over it.

                  See what happens.

                    Go on a 7 day backpacking trip in the winter in the snow, wear cotton socks on one foot and wool socks on the other, then get back to us, also no one is claiming that wool is water proof, we are claiming it keeps you warm even when it is wet. You are so disingenuous it physically hurts, like the frostbite you will get on your feet if you don’t use the correct socks.

      Bro, have you see how wool reacts with water?

      No way wool is keeping you warm in the rain without something water-resistant over it.

        Wool most certainly does keep you warm when it is wet. Sheep dont have a water resistant layer and they live outside. On the other hand cotton will literally wick the warmth away from you when it is wet.
