Terrific base layer
Review by Saul S. on 11 Feb 2025 review stating Terrific base layer
I’m all set to hit the slopes. The 250 vase later bottoms are comfortable, and the perfect weight.

Confortable et bien ajustée au corps. Cependant, les coutures sont de moindre qualité que celles qu'on retrouve chez Smartwool.

Very surprised!
Review by Patrick N. on 8 Feb 2025 review stating Very surprised!
Glad altitude got into making their own products, love that we can support more Canadian. Surprised by this base layer outperforming some other products I’ve had with bigger brand names! Tested a few occasions in -8 weather with just simple jogging pants on and stayed warm the whole time! Will definitely get the matching top.
