Built for warmth and movement in the deep cold, this toasty baselayer features a performance blend of stretchy, body heat retaining, thermal reflective waffle fabric with Omni-Wick® stretch jersey inserts at the side/underarm—which disperse excess heat and wick sweat during dynamic activity. Raglan sleeves deliver better range of motion, and a dropped hem in back provides more coverage where it counts.

  • Omni-Heat Thermal Reflective breathable material on the core, shoulders, and arms regulates your temperature with silver dots that reflect and retain body heat
  • Omni-Wick on the sides and underarms pulls moisture away from the body and enables perspiration to evaporate quickly, keeping you dry and comfortable
  • 4-way comfort stretch for superior mobility
  • Raglan sleeves and ergonomic seaming for comfort and better coverage
  • Thumb holes for coverage and security
  • Imported

  • Omni-Heat thermal reflective waffle 85% polyester/15% elastane
  • Omni-Wick inserts at side and under arm

Perfect Cold Weather Top Warmer than it looks but does not have a lot of bulk or weight to it, perfect. December 23, 2014
Spendy but a great baselayer I have several of these shirts for work (I work outside) and they have been great. You notice the Omni-heat a lot more when you are working harder and producing more body heat but I can feel the warmth on my arms just after I put these on. They are meant to be tight so I ordered a size up so they wouldn't be quite so snug and so that I could have the added length in the arms and torso as I have a tall slender figure. I like the thumb holes and how the sleeves are longer because of this. They weren't quite as stretchy as I imagined but that may be because of the omni heat dots. Still they work well and I love the purple color (inkling). I really like the 1/4 zip feature as well since it keeps my neck warm but if I get too hot I can always zip it down. Great product from Columbia. December 5, 2014
Great shirt Keeps you nice and warm! November 24, 2014
Great choice As thin as the medium weight as far as comfort goes...seems to block the wind a bit better. I like the half zip option to keep the chill off the neck when zipped up and to let in some air when zipped down as you go from the cold outside to the warmer inside. Thumb holes are always a plus regarding quick and easy access of putting on or taking off an over jacket. Plus it helps keep the cold out when you can wear your sleeves tucked in your gloves.

Didn't want it I returned this shirt for two reasons. The washed-out red color was unpleasant and the thermal dots made my sensitive back itch. January 1, 2014
New FAVORITE! Oh my gosh, this shirt is amazing! The disco ball inside actually does make you warmer. Love the thumb holes and the zip is the perfect length. While this is a baselayer intended to be worn on adventures, it can definitely be worn with jeans and make you look great! With regard to the adventures, it is fantastic: breathable, warm, doesn't roll up when paired with a jacket. My only negative is that the material is prone to snagging, so hide your velcro.
