Never used Lululemon gym duffel bag! It’s been sitting in my closet and needs to go to a good home. Nylon fabric with lots of zippered pockets to hold all the things. The straps on the bottom are designed to hold your yoga mat. Can hold up to 50 lbs and is 17”x9”x10”. Was in excellent condition until my kitten attacked a zipper pull just before I took photos. Last picture shows punctures. Price reflects damage. Bad kitty.
