Men's Base Layer Reviews

Take it from our customers.

"Love this weight for skiing during the cold Yukon winters. The thumb holes are a nice addition. Simple and refined cut."

Benjamin L.

Inversion Heavyweight Base Layer Shirt

"These are the perfect length so they don't get bunched up in ski boots. Warm, wick well and comfy."

Paul J.

Aspect Midweight 3/4 Length Base Layer Bottom

"I have 6 of these shirts now, I love them. I'm 6'5" 205 and have long arms, it's hard to find clothes anywhere. I like an athletic fit and these are perfect."

Anthony F.

Aspect Midweight Base Layer Shirt

"These fit great and feel great next to skin. Wick very well even when sweating from exertion and keep me dry and warm. Very good product."

Eric H.

Inversion Heavyweight Base Layer Bottom

"Exactly as described, warm and breathable, well built and soft, stretchy with a good fit, bought it for running since my last wool quarter zip has worked so well and not gotten stinky."

Mark H.

"These are the warmest and toughest under layer I have ever owned. I will be buying more."
