Meshing Around - organizer and carrier, 3 sizes by annie.com

Lightweight drawstring backpacks made with mesh and fabric are easy to make and perfect for carrying everything from swimsuits and pool toys to dance or workout gear.
Breathable mesh provides ventilation and visibility of contents, and fun fabric bases add sturdiness, color, and interest. Mesh slip pockets on the front keep essentials easy to reach.
A cinch top provides easy closure and opening. The closure straps double as backpack/over-the-shoulder straps for simplicity of design and to help ensure the bag stays closed when carrying.
Perfect for gifts, the bags can be personalized for each recipient. Choose mesh and fabrics in school or team colors for students or sports fans.
