Givi CRM102 Corium Range Side Bag - 16 Litre

Stylish and functional bag that is waterproof. Liner can be removed with contents which saves detaching whole bag from attachment straps. My only slight criticism is that the the metal closure can come undone if the bag isn't full, (not a worry as the side clasps keep the bag closed).
Also, the seat straps have to be good and tight to stop a heavy single bag pulling them down wards, especially on bumpy, uneven roads: system works better with two bags counterbalancing each other.

This bag is exactly what I wanted for my T120. Looks classic and 100% waterproof. It detaches in seconds so good for security and good for retaining the looks of the bike.

Usual excellent Sportsbikeshop service - bag is great

I recently rode the North Coast 500 on my Triumph Rocket 3R and bought a pair of these and their mounting system for the trip. Their waterproofing wasn't tested until I was almost home when on the Loch Lomond road I was caught in the heaviest rain I've ever had to ride through. The road instantly became a river, all the burns running down from the surrounding hills burst their banks, traffic was moving at just 20mph, the rain was falling so hard it was HURTING. When I got home the contents of both bags was BONE DRY.
