Have a great sporting outing with this lovely sport knapsack!!! It is made of Polyester with microfiber and mesh that gives this bag a quite solid look. This knapsack creates space to not only keep sporting items but also caters for other personal items with even an in-buit pocket to keep Earbuds and an inner zippered compartment to keep other handy essentials like wipes, mini sanitizers etc. It also features heavy duty cord straps and heavily reinforced eyelets for attachment of other items externally. For easy use, this bag uses drawstring closure to prevent that wear and tear from zippered bags. This bag should only be cleaned via spot cleaning.
