Arizona’s Sean Miller A Sweaty Mess. Undershirt Required

April 8, 2016 | By | 12 Replies More

A little over two weeks ago, U of A Coach Sean Miller was a sweaty mess during the NCAA Tournament.


The pic went viral and brands across the country seized the opportunity, and sent Sean some new shirts.

Two undershirt brands sent Sean new undershirts, and other brands sent him five different types of new dress-shirts.

Sean took note, stating that he had not tested that shirt before, and wasn’t prepared for the massive sweat-through.

Tug’s Advice To Sean Miller

  • Wear a light weight undershirt. It will protect your shirt from sweat-through, without making you warm
  • If you’re wearing a tie, wear a crew neck undershirt to avoid seeing the collar line
  • When wearing light colored dress shirts, try a neutral colored (invisible) undershirt to avoid seeing the outline of the undershirt. Though I have seen cases where white undershirts showed through less, so do a quick test with a couple different colored undershirts to see which one is least visible
  • In place of traditional cotton dress shirt that can get wet and take a while to dry, replace it with a performance dress shirt made with wicking material like Mizzen+Main or Ministry of Supply. You’ll still sweat through the fabric, but it’ll dry faster
  • Need coverage for your arms? Try a long sleeve undershirt, or a short sleeve undershirt coupled with colored arm sleeves (like tattoo cover sleeves)
  • To mitigate any sweat-through, check out sweat-through resistant shirts, like Smartweave
  • When all else fails, wear darker colored dress shirts so that the sweat is not a visible

    Hey guys… I got myself some of the nano dri shirts also… unfortunately when they arrived it was getting cold here in Australia so they wont get a full test out until summer! My thoughts so far are that they are quite thick and I do feel slightly warmer in them that others I have used… I found that they are border line on length (I don’t have to tuck just… Im disappointed in the width underarm to underarm, mine only just fit there and I would say lose some comfort because of the “skinny guy” slim fit.

    In regard to sweat dripping down your body, im sure I saw someone developing a band type thing to wear so stop sweat? It might have even been the same guy that did nano dri? maybe get in touch with him?

    all the best


    • Tug says:

      heya james, thanks for your input and feedback on nanodri.

      you’re right, nanodri also created the bodibelt, which is the band that you’re referring to.

      while you probably could wear the nanodri bodibelt under the nanodri undershirt, the amount of coverage the bodibelt gives you could be a bit overkill when worn with the nanodri undershirt.

      the bodibelt is about 6.75″ (17+ cm), so it’s fairly wide. maybe you could wear it around your hips, but i think it would gather too much during the day.

      in fact, i have a feeling that if you wore the bodibelt anywhere, it would likely gather some during the day, requiring you to adjust it from time to time.

      you mention that you’ve used other products? which undershirts/products have you tried so far, and what did you think of them?

      keeping in mind that if you only need underarm protection, an undershirt like nanodri or sutran will likely be overkill, because they have double layer protection throughout the entire product, vs just protection in the underarm area.

      so if you only need underarm protection, i would fully expect other undershirts with underarm-only protective layers, would be quite a bit lighter and cooler to wear.

      look forward to continuing the discussion (:

        Hi Tug and James,

        To be honest, for me nothing is really overkill. My body sweats like a pig and sweats come out from almost everywhere except hands and shoulders. To make it worse, temperature in Japan is like 30+C in the summer combined with 80+% humidity. I have used both the bodibelt and sutran, or bodibelt and nanodri, and I still experience some sweatiness for my lower body, especially showing on my butts.

        A follow-up question regarding the fusible interlining that you talked about: can I sew that into my jeans and trousers permanently? What you showed me I guess is temporary, please let me know if my understanding is correct. For me, any price that I must pay is okay as long as I can survive like a normal human being in the summer.

        Another question: can I use Botox to reduce/stop the sweating in the summer? How long will it last? How do I go about doing it? Hyperhidrosis is especially annoying for me in the summer.

        Appreciate any feedback you guys might have. Thanks for your time!


        • Tug says:

          heya lam, thanks for following-up.

          the fusible interlining is permanent (or nearly permanent). it uses heat to bond, and that bond is essentially as strong as sewing — maybe stronger since it’s bonded everywhere, instead of just being sewn at the perimeter.

          botox can and has been used in areas (like the underarm) to stop sweating for a period of time — around 4-6 months if i recall correctly, and depends on the area of the body you are treating. i’m sure you could learn more if you googled it, but here’s one resource article you can look at (link).

          that said, anytime you block sweat in one area, you should very well expect that it will come out in another area, especially if you sweat a lot in the area that you are blocking.

          this is generally called auxiliary hyperhidrosis, and it most commonly happens to people when they undergo certain surgeries like ets (endoscopic thoracic sympathectomy).

          the only way to know for sure, is to try it and see what happens.

          let me know what you wind up doing or trying. i would love to hear your results.

            Hi Tug,

            Sounds like Fusible Interlining would be a great option for all of my pants and jeans then. I’m thinking about taking them to the local tailor shop and ask them to attach fusible interlining to them. Do you think that’s possible?

            And I know exactly about the surgery that you mentioned because I underwent it like 10 years ago approximately. I used to have sweat on my hands and feet, so after the surgery (with some leftover scars near my armpits), my hands didn’t sweat anymore. Instead, it came out in other places of my body (like almost everywhere). I guess it’s more like a transfer of sweat location, not really a permanent fix.

            If I try Botox now, I guess it won’t be that much better?? What do you think? What I’m trying to do is permanently (or for a long period) reduce the amount of sweating, not really transfer of sweat location.

            I hope one day there’ll be a permanent cure to this, or else I’ll have to suffer at least 3 months out of the year in hot countries.

            Thanks for your awesome advice and information.

            hey lam,

            that bonding material i referenced is an at-home solution, you can install with an iron.

            but, if you don’t want to do it yourself, i’m sure you can contact a local seamstress or tailor, tell them what you want to do, and let them recommend how they’d suggest accomplishing it.

            i don’t know if a seamstress or tailor would want to use an iron-on fusible interlining, but there’s no harm in asking them.

            i would recommend starting off modifying one pair of pants with the extra layer of fabric on the backside (using whatever attachment method), and testing it out to see if it prevents enough sweat-through to be worth paying to have all your pants done.

            of course, doing it at home yourself will save money, but i would understand if you wouldn’t want to do it personally.

            i can’t really provide any advice on the botox, because i don’t have compensatory sweating, and don’t have first-hand knowledge.

            but, if you block sweat from coming out of one place, especially if its a place that has a large number of sweat glands (check this diagram), then it’s very possible that sweat will come out somewhere else.

    Smart weave are a must have for people who suffer from hyperhidrosis! Great quality and they work!

    • Tug says:

      heya james — do you have hyperhidrois? any special area that sweats a lot?

      • James


        Hey Tug, Yes, Back and Chest are the worst areas… Underarms too but I generally get botox to control that area in the hotter months.

        Undershirts are an essential item for me everyday at work, I wear them under a cotton/poly polo…I pretty much avoided any job that required a shirt for obvious reasons it just would have been an embarrassing uncomfortable day, everyday.

        Ive tried heaps of shirts with different success, my favourite used to be silverback but they are no longer.

        At the moment im using Tri-Dri which seem to be quite effective in wicking away from me but it not soaking through to my main shirt (unless im leaning back into something and then it soaks right through).

        I’ve also funded the Nano dry shirts on kick starter so am looking forward to getting those shirts!

        But getting back to the smart weave shirts…if both them and botox were around when I was beginning my working life things could have been very different! cheers mate

        • Tug says:

          great stuff james!

          if you haven’t tried them yet, you may want to checkout sutran 2.0 undershirts. they have all-over protection, and have been one of the only undershirts ever made that effectively provide all-over sweat-through protection.

          keep me posted on all of the products you try — especially nano dri — i’ll be trying them too.

            Hi Tug and James,

            I just want to contribute very quickly. I have used the Nano-Dri shirts. I love these shirts, they are quite amazing because even though I sweat like a pig all over my body, these shirts literally stop any stains from showing. Well, to be honest, if I keep staying out in the sun or do some physical activity for prolonged period of time, then the stains would color to my outside shirts or polos as well, but only a little, compared to Sutran.

            The only complaint I have about these Nano-dri shirts is that I always tuck them into my pants (because they’re long), and what happens is that the sweats drop down from my upper body to my lower body and wet my butts and it shows on my pants (especially wool pants or trousers, jeans are better)!! It’s quite annoying, but I figure that is gravity at work and I can’t do much about it. I look forward to when they invent Nano-Dri-like pants or shorts! Let me know if you have any solutions for this!

          • Tug says:

            heya lam, thanks for stopping by and posting your feedback about nanodri shirts.

            one option for you could be to tuck your undershirt into your underwear, and then even if the sweat drips down some, it will be on the inside of your underwear, leaving an additional layer of sweat protection in front of your pants.

            another option could be to find an absorbing soft fabric (cotton, viscose, etc.) from a local fabric store, locate some heat-activated fabric bonding material (like thermoweb heat’n bond), and bond the soft absorbing fabric to the backside of your pants.

            although the link above is for a united states-sourced product, i would fully expect that there are similar products you could purchase anywhere in the world.

            the commercial “industry” term for that product is fusible interlining, and there are several different types of commercial fusible interlining available. there are some consumer versions as well, like the thermoweb heat’n bond above.

            essentially what you’d be creating is lining on the inside of your pants, without paying the high costs of having lining added to your pants.

            plus, you’ll have the flexibility to choose what type and weight of absorbing fabric to put on the inside back of your pants.

            that additional layer of sweat protection will not only slow the process of sweat-through, it’ll also add a little additional layer of comfort to your back side (:

            hope that info helps! let me know what you do, and if you try one of the above recommendations.
