You thought a 3-in1 was cool? Well, it's got nothing on the 686 SMARTY 5-In-1 Complete Jacket. Of course, it comes fully loaded with 2-Layer infiDRY® fabric that keeps you comfortable in all the varying conditions that winter brings and 15K/10K waterproofing and breathability, but it can also be worn five ways. Yes, you get FIVE options in this do-it-all jacket. The vest has an ideal amount of insulation for core warmth, and works to move moisture to the exterior of the jacket to evaporate. Plus, the plethora of pockets allows you to bring just about anything onto the mountain and keep it all organized. With the addition of a stretch fleece liner and a waterproof-breathable hardshell, all the bases are covered for adjusting your layering to stay comfortable no matter the weather. Wowza, that's a lot. NOTE: The 5-in-1 I’m selling here has the Gore-Tex shell so the rating is actually 28k instead of the 15k 5-in-1’s sold online.
