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.

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.

Very comfortable and great quality

Awesome fit

I look forward to wearing this baselayer during my trip to Antarctica as it is soft, warm, and comfortable.

So soft!

I tried on these tights...so soft and comfortable! I look forward to using them on my trip to Antarctics.

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!

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.

Carrie
Women's Micro-Elite Chamois Pocket Legging - Black
Love

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.

Krista Martinez
Women's Micro-Elite Chamois Crewneck - White
Great addition to my cold weather gear

Great to stay warm and layer as needed. Fit allows you to have a true moisture wicking base layer and allows you to add this for warmth without bulk so you can add another insulating or just outer shell.

Rudy Argueta
Men's La Montaña Fleece Zip T - Black/Black
Hands down the best

Bought a full set of La Montana about 14 years ago. By far, it is the warmest and most comfortable underlayer I have ever worn. My teenager has recently taken possession of them and I know that I will not get them back. Therefore, I am preparing to order another set.

It all started in 1985, when Hot Chillys introduced the first body fit Thermal Base Layers.

Hot Chillys revolutionized the ski market with performance ski "warm wear" (base layer underwear) incorporating fabric technologies previously found primarily in running apparel.
