Yeah that new Endura MT500 felt like a well made jacket when I got my hands on it. I’m a tight bar steward though, so not a chance!
I am used to heavy duty offshore waterproofs, obviously not practical for bike usage, so everthing else always seems like a bin bag with pound shop zips and poppers to me!
Got the Maddison Addict, IMO a fair quality/price trade off 3 layer MTB specific jacket, which fit’s me well and seems well designed for it’s purpose (the chest vents will divide opinion I’m sure). I will say the zips and poppers seem a bit flimsy (especially the hood attachment) and the shell material, unsurprisingly feels marginally thinner/less rugged than the much more expensive MT500. It’s survived one minor offage so far!
You want a 3 layer fabric, vents are a must IMO, beyond that it’s down to price, features and vent position preference.
