Sport packs are lightweight drawstring bags you can use to store your martial arts gear. You can slip your arms through the drawstrings to wear one like a traditional backpack or simply carry it by hand. They measure 13” wide and 16” high and are made from nylon material. Some include a ventilating mesh section to better air out your equipment. These bags are available in multiple colors and screen-printed designs from brands like ProForce, Lightning, and Gladiator. AWMA offers free shipping on U.S. orders over $50.
