Can fit a 15” laptop in padded sleeve with Velcro strap closure. Adjustable shoulder strap with sliding, removable pad. Multiple slip and zipper pockets. Key leash. Vista loop for attaching blinky bike lights. Easy wipe internal TPU liner. 100% recycled polyester from post-consumer materials. I’m even throwing in a Timbuk2 bottle opener that has a Velcro to attach where needed! Very good, lightly used condition. Well taken care of.
