I was in Decathlon the other day and did wonder whether some of their stuff might be OK for a season or two, seeing as it was so cheap. Any particular model strike you as being good?
Decathlon kit is good value but, as already mentioned, some of it can be noisy. I am not sure that it will soften/quieten over time.
Have a look for the "silenthunt" range in Decathlon which is very quiet.
These are worth a look if you look camo: https://www.decathlon.co.uk/actikam-500-waterproof-hunting-trousers-camouflage-id_8365041.html
