It's a discontinued model. It's a rare type with the old tag, side pockets, and compression straps. The back padding and straps are not flimsy, but have thick padding. I have used it carefully for a long time, and it's very easy to use for travel and low mountains. Gregory bags tend to become sticky inside due to hydrolysis, but this one has no issues. *The bottle holder on the strap is sold separately. Please feel free to ask any questions in the question section.
