Givi EA148B Roll Top Rucksack - 20L

Sturdy, comfortable and exactly what you would expect from a waterproof backpack for riders. I purchased this for commuting to office and carrying laptop, electronics and paperwork. Everything arrives safe and sound and no water damage. Exactly what you need in the UK. Also added bonus of laptop sleeve to hold it in place. Plenty of room as well, can even carry over night stay of clothing etc. highly recommended.

From a few uses it seems pretty much fully waterproof. No issued at all with that so far. Sits comfortably and isn't to bulky despite the fact you can get loads in here. I had a 22l backpack before and this is easily bigger. The shape allows a lot more in as well. Highly recommended

Rode back from Chester to County Durham in torrential rain for the whole 125 miles. Everything bone dry and the back pack is compatible with zero movement.
