Perfect ski guide pack
Used it this past winter in the wasatch and guiding day trips in the southern Sierra. It's the perfect size for 1 day trips as a guide or 1-2 day trips for the average user. Still in the first season so can't speak specifically about the durability but is holding up thus far.
Wouldn't recommend for people with a torso length longer than 21in but should fit great for everyone else. Provided it fits I would call this the perfect all mountain day pack.
