Someone requested details on a one man tent 2/3 seasons and not too expensive for riding and walking, but I can't find the thread (oops!!).
I'd probably recommend the Wynster Prairie (season at £34) at www.cheaptents.com (UK company with shop and helpful staff) or alternatively for a ultra-light you could go for the Micro Zoid by MSR (http://www.cheaptents.com/acatalog/Product_Catalogue_Products_28.html#micz) - 1.3kg and recommended all over the place!!! £110 too.
For walking gear there's alway www.walkandramble.co.uk for clothes and boots - there's some good ones called Hillmaster by Brasher (I've got some - perfect fit and are comfy all day - £100).
Let me knwo what you decide anyway and if I can be of any help I will!!!
Tara for now,
John
