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
  • Antimicrobial treatment protects this product from bacterial growth
  • Raglan sleeves and ergonomic seaming for comfort and better coverage
  • Imported

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

Cool It needs thumb loops. December 12, 2014
Worth of it Light weight, dries faster and good looking. Long enough sleeves for 6.3 feet tall persson. This one covers my wrists comfortably. I wear this for day hiking and shorter distance running. I love this. December 11, 2014
Light and warm I own the top and bottom, love them both. They both are very comfortable and warm. I really enjoy how light and cool they feel, even when they're keeping me warm. June 11, 2014
The product is light and warm. Just like the Omni heat baselayer, especially in the cold winter of East Coast. March 4, 2014
Base Layer/Run shirt. Dual function Shirt is awesome to run in on those cold days when I'd rather stay in sipping coffee and reading the paper. Wicks away moisture, traps in the heat. March 1, 2014
Snags very easily Great fit, beautiful color. Very warm. But it snags very, very easily. I just cut off the snags (after one wearing), and we'll see how it weathers laundering. February 12, 2014
Rockfishing Very warm and comfortable! February 10, 2014
Very Warm but poor materials This base layer is very very warm, but within the first day of light use, strings were coming out of it and the shirt unraveled. So sad=[ February 3, 2014
Absolutely Worth the Money This shirt was a gift for our son and it came just as the temperature dropped outside and he was absolutely pleased, warm and comfortable in this shirt and it did everything that they said it would - January 27, 2014
Superb product Put a t shirt under it and layers on top and works well in minus 10 degrees. I buy for family member who works in cold storage at minus 10. He says they are great! We use for wearing in our Chicago weather and it felt really good when it hit minus 17. January 19, 2014
Keeps my son warm and toasty My 15 yr old likes to run around without a coat and is always cold. Now that he has his Omni heat shirt, he says he toasty all the time. January 7, 2014
Storage !!! OMG Looking forward to wearing this coat more I have been working where the coat would have been damaged so I have only wore it 3 times but with 2 cell phones a wallet I keep in coat pocket instead of back pants pocket. Also I am using a heart monitor for 30 days so the receiver fits perfectly in the pockets. each cell phone the monitor my wallet and keys all in separate pockets with still more to use. Overall great so far cant wait for the future December 31, 2013
Looks good fit perfect Looking forward to trying out the new top, fit was perfect for me. I like my thermal tops tight which this feels perfect. December 11, 2013
