Good quality

Very warm good durable and cozy I wear in Alaska on the north slope -20 degrees

Charles Henry
Men's Micro-Elite XT Zip-T - Black/Grey
Too Fuzzy

I was not expecting the product to feel like a blanket. So soft but too thick.

Peggy Meeks
Women's La Montaña Fleece Zip-T - Black/Black
Best cold weather turtle neck.

I have bought these for years! Love the warmth and no bulk.

DIANE PERLMAN
Women's Peach Skins Solid T-Neck - Lagoon
Better than expected

This shirt was for my husband an avid cyclist and contractor for biz and said this has to be the best shirt I’ve worn. ( trust me…he owns many of the big name brands) He said most shirts you get hot in at some point (cotton and tech) but this fabric not only feels amazing it’s so breathable! Keeping him comfortable and dry all day. He’s just ordered the hoodie and another T shirt.

Patti Fisher
Men's Clima-Tek Crewneck - OD Heather
Great T-neck for cold days

I bought this for next season so haven't worn it yet, but the quality is very nice, I like the chamois inside and it's nice and thick for winter sports. I like that the zipper has an extra flap to protect the chin from chafing. I will wait for the white to come back in stock - hopefully this fall.

Review of balaclava pt 2

… this thing keeps getting better! I didn’t even know this thing had a hole for a pony tail! If I could give this thing more stars I would. Perfection.

Carrie
Women's Balaclava Hoodie - Black
Had to buy these :)

I had purchased the top separately and loved it, so I purchased the matching pants, and love them as well. A smooth and snug fit. You will not be disappointed!

Bruce D.
Men's 3D Knit Bottom - Black
Warm and comfortable

I bought a set (top, bottom and socks). To take on a Kansas Late Season goose hunt. They were VERY comfortable and soft against my skin and kept me warm while laying in my layout blind. Very happy with my selection.

I returned this item because it felt too tight on my face

Susan Heard
Chil-Gard Micro-Elite Chamois Solid Half Mask - Granite
Great product

I wear a medium and it was very tight. Going to gift it to. Daughter in law.

Peggy Seale
Women's Balaclava Hoodie - Aerial Blue
Perfect layer for everything!

I wear this as a base layer for downhill, Xc ski, running even walking the dog! Brilliant all in one hood, face mask and cozy fuzzy inside, like the hand of this even better than my R1 Patagonia. Wore it for 7 days straight without washing and never got smelly.

They are cozy on the inside and slick on the outside! Love them. Skiing in 20 degree weather and didn’t get cold at all.
