AUTHOR SuMo Waterproof: Your Ultimate Adventure Companion

Travel Light, Stay Dry
Planning a weekend bikepacking trip or a long-distance cycling tour? With the AUTHOR SuMo seat bag, you don't need a heavy metal rack. The bag attaches directly under your saddle and features a variable volume that adjusts from 5 up to 13 liters.

Total Protection Against Water

• Don't let mud or heavy rain stop you. This bag combines extremely durable outer fabric with an inner waterproof liner featuring taped seams. Your clothes and gear will stay bone-dry no matter how wet the road gets.

Solid and Stable Fit

• Forget about the annoying side-to-side sway common with large bags. Thanks to the dual velcro straps on the seat post and a specialized compression strap for the saddle rails, the bag stays perfectly stable even when fully loaded and riding through rough terrain.

Key Features:

• Adjustable Volume: The roll-top closure allows you to compress the bag to the exact size of your load.
• Easy Packing: The main section is reinforced, so the bag keeps its shape and is easy to fill.
• Extra Storage: An elastic bungee cord on top is perfect for quickly stashing a windbreaker or a rain jacket.
• Safety First: Integrated reflective elements and a dedicated loop for your rear light ensure you remain visible.
