Avenir Expander 2.0 Seat Bag (Large- 55/73 Cubic Inches)
Want just a little more room when stuffing gear into your bicycle seat bag? Turn to the Avenir Expander 2.0, an adjustable version that stretches from 98 to 200 cubic inches, giving you plenty of space for extra tools, energy bars, water bottles, and more. The bag is made of durable 420-denier ripstop nylon, with a classic parallel zip design for easy access. The bag's wraparound reflective stripe, meanwhile, is ideal for dimly lit days and evenings. And users will love the sturdy hook-and-loop mounting system, which attaches securely to the back of your bicycle seat. Also equipped with a rear tab that holds a reflective taillight (sold separately), the Expander 2.0 is a must for frequent cyclists.
