Lone Peak's Micro Seat Pouch features one main compartment to store all of your cycling essentials. Made from rugged, water-resistant 1000 Denier Nylon the Micro-Pouch connects to your seat post with a hook and loop closure system and a quick-release strap system that goes through your seat rails for a universal fit. For added visibility and safety at night, we sew 3M Scotchlite reflective material onto the rear of the Micro Pouch. The Micro Pouch is perfect for the minimalist or that racer looking for a small, durable and lightweight seat pack. The Micro Pouch is perfect for wallets, keys, tools, tire levers, patch kits and other small items.
