So I got my bag at Xmas time this past season. Used it about 10 times so far. Offering an alternate opinion since everyone is posting glowing life changing reviews.
The bag itself is pretty high quality. My son has a non-heated version from when he was a ski racer.
I'm not sure heating my boots in the bag is miraculous as everyone said. I think it's good, but I'm ok without it also. Maybe I just have hot feet. I don't find the bag heater really dries boots. I have to take them out and use my boot dryer.
Even though the bag stores a lot, I don't really like the small openings for the goggles and main pocket. Its great when you are finding stuff at the top, but hard to find things a little lower. Also if there is anything damp, it doesn't dry out. Not really enough room for a jacket either.
I guess I was just used to my large duffel bag and boots over my shoulder. I'm still using it, but probably wouldn't buy another.
