They are pretty fat, 125 underfoot, they are too wide to fit in the ski slots of the gondola! I also own some oldschool K2 hellbents that are 132 underfoot. Really great skis to have on a heavy wet pow day like this one, the flashy color and overall largeness always gets lift line comments.
Ah, 176 thats not bad. Thats how long my On3ps are and I'm an inch taller than you. I couldn't imagine skiing something that Wide though! Widest I've ever skied was 95under! But then Midwest - I got One powder day this whole season.
125 I've decided is as wide as I'll ever need, having skied wider it's just becomes more cumbersome than helpful after that. Since moving to Utah 4 years ago they've managed to keep having their worst season ever, so powder days have been getting increasingly rare, I think I got 6 good ones this year, which is really low compared to when I lived in Washington. At least in Utah I get to see the sun, and the terrain parks are actually good.
