eoGEAR Zippered SeatBag™ 4.8


This bag is an evolution of our popular 2.3 SeatBag. We took the 2.3 and made it taller and thicker, providing over twice the capacity. This is a new in-between size bag — not as large as full-size RandoBags, but yet, much larger than your typical wedge bag. 
The bag attaches in two places to your bike: one, to any round seat post up to 35mm in diameter with an integral clamp (made by SKS/Germany) and two, using a pair of Velcro-like straps to the rails of your saddle. It is very quick to attach and detach.

FEATURES—This bag has one main compartment and two outside pockets. This bag has a built-in clamp for use on round seat posts (made by SKS Germany). It will not attach to oval posts. This bag is similar to an internal frame backpack as it has a built-in HDPE framesheet and has a compression strap, for reducing the size of the bag when contents are removed. This strap also keeps the bag from swaying when it is loaded down.

MAIN COMPARTMENT—Holds a small jacket, arm warmers, spare tire, repair kit and snacks. It has an easy-to-use horseshoe-shaped zipper that is water-repellent (it is chemically treated).

OUTSIDE POCKETS—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. On the right side is a mesh pocket with an elastic top.

CONSTRUCTION—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. On the back of the bag, near the label is a pair of D-rings (unlike the photos), for attaching extra gear like a stuff sack for a rain jacket etc.

COLORS—Currently available only in black and dark gray as shown, but other colors may be available by special order (inquire via e-mail).
