Gearing up for a big ride or just need more storage for your daily commute? The Serfas Double Pannier Bag in Black/Dark Gray has got you covered – literally. This 2021 updated design securely mounts to your rear bike rack, offering a massive combined capacity of around 40 liters (that's about 20L per side!). It's built tough with reinforced bag edges and a rigid back panel, so it holds its shape even when packed. The quick-access flip-top closure with a single buckle makes getting to your stuff a snap, and there's a handy top grab handle for carrying it off the bike. Safety is key, so it includes a reflective patch and even two attachment points for your bike safety lights. There are also zippered flap pockets for smaller items you need to keep secure. Made from water-resistant materials, it'll help keep your gear dry if you get caught in a drizzle. It's also 'Deck Bag Ready' with a center hook and loop area. Each side measures 15\ H x 5.5\ D x 15\ W. Serfas backs it with a Limited Lifetime Warranty, so you know it's built to last. Perfect for touring, commuting, or any adventure on two wheels.
