Questions & Answers

Ask a Question
  • How tight fitting/stretchy is this?

    These do not have skin tight athletic cut, but they're not baggy or loose fitting either. They are true to size and should fit like an everyday T-shirt.  Merino wool fibers have a nice natural stretch, much more so than cotton, and our lightweight tees will move with you comfortable and easily during rigorous activity.  

  • What is the difference between this shirt (Men's Basix Short Sleeve Crew Neck 160 Ultra Lightweight) and the Men's Outback Short Sleeve T-Shirt 160g Ultra-Lightweight?

    The only difference between our two lightweight tee shirts is the weight of the merino wool fabric. The Outback tees are a slightly heavier weight 160 g/m2 merino wool while the BasiX tees are made of 150 g/m2 merino. The difference is very slight and not obviously noticeable to the touch. We created the BasiX tees as an introductory line that we could offer at a slightly lower price for people who had never tried lightweight wool before.
