I took my first pair of ColdPruf Quest performance base layer top and bottoms out on their inaugural adventure back in October in some pretty unusual backcountry conditions: elk hunting in cold, wet, miserable weather made worse by the body aches and chills that were my daily and nightly companion thanks to a bad flu. No joke, my ColdPruf base layer may have kept me from packing up my tent and heading home early. Hands down I have never worn a warmer set of technical undies in my life. Even with night sweats and teeth-chattering chills in my winter-rated Montbell down bag, I stayed warm and was able to get back to sleep once the Benadryl kicked in. The next time I had the chance to put them to the test was in some windy, freezing early-season ski conditions in Canada. Despite the brutal weather, I stayed plenty warm on the exposed, sedentary rides up on the chairlift and never over-heated plowing through powder piles on the way down. I have since put in seven ski days and several fat bike rides in my ColdPruf Quest tops and bottoms and won’t be leaving home without them this winter on whatever adventure I end up on.

OTM also tried out the women’s Honeycomb fleece long sleeve base layer top and bottoms. Our reviewer noted that she liked how the cut is feminine but not baggy in places that don’t need to be. And she loved the heck out of the overall warmth of the garment and the comfy fleece touch against the skin. “I hate being cold – hate it – so I love how warm they kept me. It’s a solid, thick base layer and stylish enough that I found myself wearing the top out and about on everything from frosty morning runs to work-day errand runs.” http://www.coldpruf.com. //
