  • “how much does a small weigh?”
    Asked by Reverse from NZ on 6/30/2015 1:50:56 AM
    • I would say a couple ounces at the most
      Answered on 6/30/2015 3:39:02 AM by Mike J from Michigan
    • Hardly anything at all, weight is not a factor. I would buy a next size larger unless you want a skin tight fit which some people do. I'm happy with the Terramar Helix T-shirt and my grandsons got a lot of use out of them in the spring baseball season.

  • “I'm 6'2", but I hate having to buy XL just to get a little height, and having to put up with extremely loose-fitting clothes. Since there is no Tall size, can you tell me how much the height goes up with each size increase? (It seems that some clothes get taller as the size increases and some don't.) Thanks.”

    • Hello

      My husband is 6'2 lean athletic built, I got him XL to compensate for arm's length and since this is a slim type design it is compensated and worked out Okay.

  • “How well do these avoid retaining odors? I know they are "treated," but still...”
    Asked by Twilly from San Jose CA on 2/1/2013 12:00:00 AM
    • The fabric is constructed from special yarns which contain huge amounts of micro parts on the surface of the yarn. The micro pore s are an inherent feature of the carbon and natural mineral elements from which the yarn is produced.
