When you hit the top of the skin track and that quickly cooling sweat starts to make that thirty degree temperature feel more like negative thirty, pull the FlyLow Men's Rudolph Down Jacket out of your pack and stay warm while you rip skins. The 800 fill DownTek hydrophobic down has a high warmth to weight ratio and will resist moisture, so it won't loose its insulating properties if it happens to get wet. In addition to the treated fill, the shell is treated with a DWR finish so snow flurries will bead up and roll off. FlyLow incorporated 6 inch underarm zips so you can let some heat out if it gets too warm. The stowable design lets you easily throw it in your pack when you head out for a tour, and it doubles as a pillow when you're catching some z's in the passenger's seat on your way to the trailhead.
