When to wear it:
In the winter I do a lot of resort skiing, ski touring, and a bit of trail running on the in-between days. The High Route Grid Air is simply the perfect baselayer for these cold-weather activities. It is highly breathable, so I stay cool if I strip down and put my outer layer(s) in my backpack. Plus, the grid fleece interior is super cozy and warm when wearing other layers over the top.
The biggest issue I’ve had with this piece is that I’m wearing it too often…it just works that well for my everyday activities. It’s a synthetic fabric, and while it’s true that synthetic baselayers have a reputation for becoming a little stinky after heavy use, the High Route Grid Air fabric features anti-odor technology which really does make a difference. Still, this layer is meant to wick and absorb perspiration, so it’s a good idea to wash it frequently (just follow the care instructions).
The piece has an athletic, close-to-body fit, which I really appreciate as I don’t like baselayers that are too boxy or baggy-feeling. There are also some sneakily-placed thumb loops in the wrist cuff. You won’t notice them if you don’t need them, but if you’re moving at an aerobic pace right on the line of sweating and being too cold, they can be the perfect way to add a little extra degree of warmth at the wrist and back of hand. It comes in a Crewneck and a 1/4-Zip, and personally, I really like the 1/4-Zip. Unzipping is an effective way to dump a little more heat if I’m really working hard and sweating a lot.
Overall, the High Route Grid Air is an indispensable piece of kit for all my winter pursuits, and I definitely see myself having plenty of use for it in all four seasons.
