No stores I won't buy from. I buy my winter walking trousers from Trespass. Realy warm and very waterproof.
I buy my base layers, walking shoes and sports socks from Sports direct. My summer waterproof Jacket is a Trago mills cheepo one. My winter jackets are ME, from Cotswold out doors. My boots and most of my climbing gear is from Go Outdoors. My walking socks are from Peacocks.
Basically as I have only been back walking and climbing for about 6 years I am still experimenting and prepared to try most brands and items. If I find one that works then I will buy it again.
Perhaps surprisingly much of what works for me is from the cheaper brands and stores. I' m happy with that.
