[Closed] Endura MTR Jacket?

I've had a search and not much has come up anywhere.

I'm looking for a new riding jacket for general trail riding. I don't normally wear one unless its either really cold or wet, so I want something I can keep in my pack but still be comfortable in for a few hours without overheating. I've been looking at the Endura MTR, helium and a couple of their other jackets. I've set myself a budget of £100 as I need to buy other kit for an alps trip next summer.

So what do you guys recommend?

My current jacket is a cheap £40 polaris number from halfords a few years ago. Its OK since it was nikwax'd and got me through some terrible weather, but not very breathable though.

Thanks in advance.
Pete.
