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

Women's Heavyweight 1/2 Zip is rated 4.5 out of 5 by 11.
Rated 5 out of 5 by from Looks and feels great This product runs very small, I usually take a med and I have a large. I have average size arms and it is still a little snug. It feels great too wear and looks nicer than a casual wear shirt.

Rated 5 out of 5 by from Helpful I recently migrated to Winnipeg from Philippines so I am not really used to cold weather. I wear this base layer together with the winter jacket I bought from the Philippines. I may say that its really helpful cos i wear this when weather was -10 but feels like -18. I will know if this can stand -20 and more. Its pretty warm and can protect my body that is not used to so low temperature. Its worth it..

Rated 4 out of 5 by from shorter arms than previous versions I purchased an Omniheat baselayer top with thumbholes in 2012, and absolutely loved it. I still use it, and it's great. Mainly, I really enjoy the thumbholes, and the reflective inside. I usually wear an XS, but I went with a S in this product back in 2012 to mitigate the fact I have long arms. So I ordered the same product again in a Small, with confidence. However I was slightly surprised to discover that the thumbholes in this newer version dig into my hands a bit. I don't enjoy wearing this one as much as the old one. Depending on my activity, I choose the one that fits me better. Often with this newer one I get thumbhole fatigue and have to remove them, and this is disappointing because half the reason I bought these tops was to keep the cold air from creeping into my sleeves.

Rated 5 out of 5 by from 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.

Rated 2 out of 5 by from 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.
