In reply to Removed UserThe_blur:
My Salomon 12 series has lasted a good 8 years (outlasted many pairs of trainers and is cheaper than new shoes too!). It has the odd small hole now and very occasional sticky zips, but overall I love it. I get on much better with it than a bum bag, and also only use the 12l now - I used to have an 8l but have leant it to a friend and don't miss it
The races I (used to) do all have kit lists, so I do most of my training runs carrying full kit in my vest, as then I am used to it come race day. I also therefore am more likely to take gear with me that will be essential if I twist my ankle etc - particularly relevant now
I have a Raidlight 20l vest for longer adventures, and would definitely consider their range if I ever have to replace my salamon 12l, as the Raidlight is really comfortable and hard wearing
Friends with Decathlon vests have been irritated at the lack of accessible pockets (meaning having to take it off to access food etc) though this may now be fixed on newer versions. I have also seen friends struggling with the chest straps on the Inov8 vests if wearing gloves
