I'd give 'em 5 stars, but dammit, I hate ugly steez, and these are steez-alicious. If you like Grenade gear and the look of most Burton stuff because the concept of a color aneurysm is cool to you, then you should buy these gloves for looks.
I happened to buy them for spring riding/skiing. They breathe pretty well, are comfortable in the snow or in 40 degree weather, they're tough, and most certainly (and best of all) really, really flippin' waterproof. I have large hands and they fit remarkably well: probably the most comfortable glove I've worn, and I'm a pretty dedicated Hestra wearer. Buy a pair and hate the color scheme, but enjoy the gloves.
