100% Protection Against Water
The AUTHOR SuMo bag is ready for any weather. It combines a 600D polyester outer shell with an inner liner that has taped seams for absolute waterproofness. This ensures your clothes and other gear stay completely dry, whether you're riding through puddles or get caught in heavy rain. The entire surface is also washable, making it very easy to clean after returning from muddy terrain.
Stability Without Compromise
Forget about the annoying swaying of the bag from side to side. The fastening system uses a combination of two strong Velcro straps on the seat post and a special strap for the saddle rails. This solution ensures that the bag stays firmly in place, even on challenging terrain and when fully loaded. The main section is also reinforced, so it keeps its shape and makes it easier for you to pack before your trip.
Practical Details for Every Journey
The bag also considers the little things you'll appreciate while riding. On the top, you'll find an elastic cord for quickly stashing a windbreaker or rain jacket without having to open the main compartment. To increase safety in low visibility conditions, it is equipped with reflective elements and also includes a loop to which you can easily attach a rear flasher light.
