Revelate Designs Ultra Shrew
Compact seat bag made with lightweight Ultra fabric.
* Next availability late May, available on back order.
Built for big rides across any terrain, from desert to snow, road to singletrack. The Ultra Shrew is a compact seat bag for carrying spare layers and small essentials. It offers 2.25 L of capacity, weighs under 5 ounces, and is made with high-performance, lightweight Challenge 200 Ultra fabric.
Mounting solely to the saddle rails, it offers maximum versatility. Dropper, suspension, aero, and high setback seatposts are all compatible, providing a near-universal fit across a wide range of setups.
Independent rail straps with hypalon wings wrap the saddle rails, connecting to a fiberglass stay for added structure and compression. A roll-top opening provides easy access without a zipper to get gummed up by mud and grime, and a rear stabilization strap prevents sagging.
The Ultra Shrew is a great choice when you need compact, stable, storage in a lightweight and durable bag.
