eoGEAR Zippered Seatbag™ 2.3-IA


  • This bag is for those looking for something larger than the typical mini wedge bag. It is about twice the size of those. It attaches to any round seat post up to about 35mm in diameter with an integral bracket or clamp. It is VERY fast to attach and detach.
  • This bag has one main compartment and an outside smaller pocket. This bag has a built-in clamp for use on round seat posts (made by SKS/Germany). It will not attach to oval posts. Similar to an internal frame backpack, it has a compression strap, for reducing the size of the bag when contents are removed. This strap also keeps the bag from swaying.
  • Holds a small jacket, arm warmers, repair kit and snacks. It has an easy-to-use horseshoe-shaped zipper.
  • The outside zippered pocket is a good spot to store cash and I.D. It will hold the optional vinyl wallet (# 4915). Also included is a lanyard for your keys. It has a pair of pleats in the fabric to accommodate bulkier items without interfering with the volume of the main compartment.
  • The exterior of the bag is constructed of rugged 400-denier Nylon Pack cloth or 420-denier Ripstop Nylon fabric (with a water-repellent coating on the inside of the fabric; we don't use cheap polyester fabrics like some imported bags). The main compartment has heavy-duty #8 water-repellent zipper. The outside of the bag has reflective strips for use in dim light or night riding.
