The Doggy Bag. Not the kind you get when you leave a restaurant this kind of doggy bad is a mesh carry-all for all your swimming equipment. When I first started to swim on my own besides goggles and a swim suit I went and purchased a kick board, a pull buoy and swim paddles. I also was swimming at the gym so I'd pack all of that except the kick board into my bag and then unload the stuff in the locker room and trot downstairs to the pool with my stuff. Hoping not to drop anything on my way down the stairs. If only I had a doggy bag. Not only would I be able to carry them downstairs I could then bring everything home, toss the bad with everything in it in a dry spot and not have to repack my swim pack again with the equipment and clothing. These days I only bring paddles and my own pull buoy but I see a few other swimmers bring more swim tech toys to the pool. All of which they carry in one of these doggy bags. At $10.50 at tyr.com it's a perfect little gift for the swimmer in your life. Oh and it comes in various colors, I just like the pink one.
