https://www.montbell.us/products/dis...06103&gen_cd=1 Montbell is a Japanese company that makes outdoor clothing. I have a light weight insulated jacket of theirs that weighs a mere 8 ounces and has provided excellent service for 10 years or so. They also have ultra light wind shells weighing 2 ounces. In cooler temps one can wear layers underneath so a shell is quite versatile and I know the quality to be very good.

I just googled montbell-uk and found a UK based dealer. https://backpackinglight.com/forums/topic/54167/ .
