Currently have a camelback blowfish, which is great for getting to the trails but i find it moves around a lot when going downhill, doing jumps etc. which i thought would be for all bags but my mates say there's don't.
It will need to be big enough for all day riding and trips to wales etc.
I'm tall and skinny if that changes anything.
Looking at the evoc bags, but they seem quite expensive and i've just missed out on the crc private sale
Are they worth it? which one would suit my needs? what else would you recommend?
