It can be difficult enough to find room enough in your bag for your toiletries, so a bulky dopp kit isn't going to help any. Still, a well-made dedicated bag for your toothbrush, soap, etc. is a lot better than the plastic disposable Ziplock alternative. The Topo Designs Dopp Kit is the best of both worlds - boasting a slim format that's easy to pack away, but with a USA-made construction that can take a beating. It also helps that it features a 1000D Cordura nylon exterior, water-resistant pack cloth lining, a YKK zipper with a paracord pull, and a webbing handle loop. Plus, the triangular format is perfect for keeping the bag flat on any surface without compromising your access to the stuff inside of it.
