The Altura Thunderstorm City Waterproof Cycling Backpack 20L is a slimline version of the ever-popular larger version but still offers plenty of storage and is perfect for the commute with those everyday essentials.

It is 100% waterproof for use in all weathers thanks to polyester ripstop material with TPU coating certified waterproof to level IPX6. Reflective print panels help keep you visible to other road users and there is even the option to add lights with three light loops for enhanced visibility.

The roll-top closure and adjustable fastening allow for flexibility whilst a detachable chest strap will keep the backpack in place during your commute. Inside there is a useful laptop sleeve to fit laptops up to 15" and a further zippered pocket to keep valuables securely in place during your ride.

*Please note the roll closure must be rolled 3 times to ensure a waterproof closure. Whilst the waterproof fabric and welded seams provide protection from the elements, this product is not submersible and should not be left sitting in water. We recommend valuables or electronics should be secured in a dry bag inside the main body of the bag for extra security
