Extremely light, compressible, and warm.

The Mammut Women's Biwak Pro Insulated Jacket is a versatile piece that works as a midlayer for snowy weather or a standalone for bluebird ski tours. Primaloft Gold gives this jacket a surprisingly amount of warmth for how little it weighs, and it's so compression that the Biwak can stow inside its own pocket. Mammut wrapped the Primaloft Gold up in superlight, windproof Pertex Quantum. Polartec Power Stretch Pro stretch panels make sure you can ski freely, and the front pockets are accessible even with a backpack or harness on.

A little different than the picture

    This jacket is nice, but the inside is bright pink... Kind of misleading! It's a nice jacket, but once I saw the bright pink inside I new I was going to return it because pink is not my color (hence why I ordered black)

    Lightweight and warm

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: M

    I LOVE this jacket. It's incredibly warm for its weight and compresses down to practically nothing in my pack or suitcase (however I was not able to pack the jacket into the chest pocket as advertised but maybe I didn't try hard enough!). The elastic sides and shoulder panels allow for great freedom of movement. I also like the longer collar length to keep drafts out. I bought the M which is a shaped, flattering and closer fit but does not allow for a lot of layering underneath, which is fine for the purposes that I will use the coat. The pink bright but not too bright and is a nice change from my normal black.
