The Vigo double bike pannier is made from waterproof polyester. The flap falls nicely over the pannier, making it water-repellent and offering ample protection against light rain. However, if you want it to protect your gear against heavier showers, we recommend buying a New Looxs rain cover for double bike panniers to go with it. With a rain cover, all panniers are waterproof. The panniers main compartment is a very generous 18.5L and closes with a drawstring to keep things neatly together. The flap is then closed with a sporty metal hook closure. The bags feature 2 extra front pockets and 2 elasticated side pocket which will easily hold things like a water bottle. The bag has features reflective detailing for more visibility in low light conditions. A LED light can easily be fixed to the bags thanks to the straps on the sides of the pannier.The bike pannier is sturdy and keeps its shape well due to the plastic plates in the bottom and back of the bag. In addition, the bike pannier has extra foam reinforcement, so it doesnt lose its shape, making it easy to stow things in the bags. All these features make the Vigo Double suitable for shopping trips, biking to the office or school and of course its a great accessory for leisure rides. **Mounting System - RackTime Snapit**Integrated Racktime Snapit adapter fits Racktime luggage carriers commonly used on fully equipped bikes from brands such as Specialized, Cannondale & Cube among others. So, check whether your bike has a Racktime carrier! The bike pannier has a pre-mounted Snapit adapter, so the bag clicks quickly onto the luggage carrier. You can adjust the adapter to fit both wide and narrow Racktime luggage carriers. You can release the bag from the bike with one swift. The advantage of the Racktime mounting system is that the bike pannier is always properly secured to the luggage carrier, so it stays in place and doesnt slip about. A small Velcro strap allows you to fix the bike pannier more securely to the sides of the luggage carrier. **Key Features:*** Mounting System compatible with RackTime Snapit luggage racks* Double bike pannier made from waterproof polyester* Quick and easy to attach and remove* Drawstring closure with top flap* Main compartments and four extra pockets* Attractive design* Reflective details for more safety* Dimensions: 31 x 15 x 40 cm (x2)* Storage Capacity: 37 Litre
