My review is for the LARGE bag
I bought the large "Main Body- Black" bag and a black strap. I didn't like the few flaps that were available. The bag has been awesome. I used velcro to seal the top of the bag and it has served me VERY well. I wish that 'crocs' had not discontinued them and instead had increased options/colors! My bag endured travel, washings, and my husband! I think it is great, even w/o a flap and I am about to order the small one with strap, since they no longer have the large (:-( ) one.
