Gravity Backpack. Used twice and stored at home. This is a discontinued model. I am selling it at a bargain price because I no longer use it. I think it can be used for mountain climbing, backpacking trips, etc. The rain cover is missing. Overall, it is in good condition. If you have any concerns, I can add more photos, so please feel free to ask. Thank you for your consideration. - Brand: Gregory, made in USA - Color: Blue - Size: S50 - Straps: Adjustable shoulder straps - Waist Belt: Padded waist belt - Model Name: Gravity Thank you for viewing.
