My Favorite Base Layer
Verified Buyer Reviewed by John@Duluth from Duluth MN on Sunday, October 16, 2016
This shirt provides warmth, while wicking moisture during aerobic activities. Exceptionally soft and comfortable; the brushed-fleece interior feels great against your skin and the 4-way stretch never feels's like a warm second skin.

  • Super comfortable
    Verified Buyer Reviewed by North Shore Hiker from Schroeder, MN on Thursday, February 15, 2018
    Love this shirt. I wear it as a base layer for snowshoeing or as my primary garment to work. Great fit, very comfortable, and keeps me dry.
  • so soft
    Verified Buyer Reviewed by budgetshopper from Idaho on Wednesday, February 14, 2018
    This is a fantastic underlayer. Regulates heat well and is so soft. I love the thumb holes. I also love that it is quite long in the body so that it stays tucked in. I'm 5'8 170# and not in the best shape. I wear medium in most brands. This is very tight on me and I could probably size up. As an undershirt, the tightness is good, but I wouldn't wear it solo in public.

    Bought this for my teenage son, and then one for my husband. They both loved it. Warm and cozy.

  • “Is the shirt supposed to fit like a 2nd skin? I'm afraid if I went up a size the sleeves would be too long”

    • Base layers are a performance-wear garment in contact with your skin; may gently hug the body and transport moisture away from the skin to the air or the next clothing layer.
