This could be perfect, but it isnt.
my nearest decathlon is 170m round trip. As I know my sizes, I often buy mail order.
Pros: material, quality of manufacture, zips, armpit breathing, weight. almost everything.
Cons: stuff sack should be built in, the product is windproof, a small stuff sack on a windy day...probably going to get lost.
This is the second walking decathlon jacket I've had, the other a more substantial one. Both are very loose round the neck with way too large hoods. It's a windproof jacket! but won't windproof the neck, and a stiff wind will blow off the hood - elastic way way too loose. Many similar jackets have no hood, so it's better than nothing. If you don't need a hood, it's still great and cheap.
If I had tried this at the store, I wouldn't have bought it, but for this price, I decided to keep it and it works ok, with a buff type product on the neck to plug the gap it leaves.
