I've managed to break the zip on my Berghaus Velum by shutting the car door on it. I've also got a hole in the sleeve from a separate incident.
Any tips on getting it fixed at a high enough standard that I don't compromise the waterproofing at all? Is it the sort of thing that can easily be done by hand, or best to take it to someone who knows what they're doing? If the latter, any recommendations in Sheffield/Peak?
