Uses Winter, Ski / Snowsports


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 to 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
  • Antimicrobial
  • 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

a perfect birthday present A perfect present for my son's birthday,the size is perfect fit, quality is great,and the package design is very creative. July 1, 2015
size too small Good product, size runs very small, I have to change from the size M to size L. June 26, 2015
Good product! Good product! It works as it should do. June 20, 2015
awesome i got this for my husband and he loves it. it really keeps the warmth in and he loves the thumb whole. he is 5/11 and 190# and fits well into the large. it is tight but an XL would be way too long in the body. March 1, 2015
Great shirt There are a number of things I like about this shirt but I'll just cover two. I absolutely love the low neck, not even mock turtle neck. By the time I get suited up to ski I feel as through I'm in a neck brace most the time. This gives me a great layer without extra around my neck. Secondly the length, no coming un-tucked, it is almost too long but I'm willing to take that over too short. February 26, 2015
Great for Snowmobiling Bought my wife a set of Baselayer last year,she loves them. I bought a set this year,They are great for snowmobiling in the single digits. February 26, 2015
Amazing I was actually very surprised at how this seemingly thin product kept me so warm on a day that was in the teens and with 7 hours of shredding. All I had on was a thin layer under this half zip and my ski jacket and I was actually hot at some points. This product is awesome, I dunno how it works but it actually felt like it was creating heat for me. Does run snug though February 25, 2015
Excellent baselayer.... My second base layer. Good quality. Did buy again. February 22, 2015
Very high quality Upgraded from basic micro fiber base layer I've had for years. Wore first time for scout kondyke camp in January. Very comfortable overnight in single digit temps. January 22, 2015
Warms Up as You Do Used this as a base layer for skiing paired with a cotton long sleeve shirt and the Whirlibird Interchange Jacket. The Omni Heat material was cool in the morning but after I got moving, it was very comfortable. It doesn't bind and fits better than similar base layers that feel super tight like a wet suit. It didn't overheat like my old thermals either. I'd highly recommend this for playing out in the cold. January 20, 2015
Very dry and warm I went to Colorado on a snowboarding trip and bought them for it. Worked amazingly, I was never cold and they were the perfect base layer for any below freezing activities January 11, 2015
Great base layer for work Bought this for cold nights at work when temps get below freezing. worked great. Sleeves on this are long enough to keep the thumb wholes from pulling back and becoming uncomfortable. Previously purchased ones that the sleeves were not long enough, very uncomfortable! December 6, 2014
Buy it Solid heavy weight. Fits true to size. not too thick like expedition weight gear. Great base layer or active top! November 19, 2014
Great product Fit well and comfortable .feel warn November 16, 2014
light nice and light but not as warm as a hoped, moisture wicking works well and great for heavy activity. January 1, 2014
Great stuff I wanted this for a base layer when I ride my motorcycle in the winter when temps are in the high 30's - low 40's. It has been a great success. This is well made, the OmniWick works really well to keep me dry even when I start to sweat. And the Omni Heat is noticeably warmer than other items without it. The best part is that this garment is so well cut and constructed that it is comfortable to wear all the time. I wear it under a tee shirt and feel perfectly comfortable. I can't say enough good stuff about this. Great experience with it. January 1, 2014
WOW!!!!!! I hunt 50+ days per year and these are the absolute warmest thermals that I have ever owned. These are for long periods of low activity as with even moderate activity you will start to sweat, even in frigid cold. This thermal with the omni heat 1/2 zip pullover is my "Go To" layering on the coldest days. Great Product! January 1, 2014
Snags Easily Loved the look and fit (size large - 6ft 170lbs). I wore about 3x before I started noticing a ton of snags throughout the shirt. Not a big deal when wearing as baselayer but I liked to wear as light jacket as well. December 30, 2013
Excellent product This is my second purchase of this product. It lives up to Columbia's hype. December 28, 2013
Sexy and Warm This works if you have a good body. If you don't, only the omni heat works. Great product !!! December 10, 2013
Poor quality Only wore it once, didnt wash it yet and its already pilling, threads are coming out, id return it if it wasnt such a hassle. November 25, 2013
