Aconcagua ML Jacket
The Mammut Men's Aconcagua ML Jacket is a magnificent midlayer to mountaineer in. Its Polartec Power Stretch fleece ensures freedom of movement on the mountains, and it wicks moisture and dries quickly for sweaty ascents. The exterior is surprisingly abrasion-resistant so you can wear it without a shell. The thumbholes keep a secure fit when you're layering.

Mammut makes good stuff, but it's as if this fleece had shrunk in the washer before it was ever worn. It fits very snugly, by far the smallest size Medium I've ever worn.
