In reply to james wardle: I can't Fault Rab for Customer service, sent me a few stufffsacs over the years without charge and replaced an old Vr top without fuss or delay. I do buy a lot of Rab kit mainly due to the outstanding service.
They once repaired my ancient Ladakh sleeping bag for a nominal fee, restuffed it, restitched it and I got another decade's heavy use out of it. I still have it and have spent well over 2000 nights inside it. Brilliant.
