Worth looking into the recently released Revit Defender GTX with goretex jacket and trousers. Super warm and waterproof in the winter and breaths really well for the warmer weather as well. Not cheap but worth it i hope
I dont realy know much about the so called TWAT jacket but the fact that it is used in the desert tells me it isnt going to be much good in the UK.Also,I guess the desert riders dont pay full price for them (if anything) and it was definitely a TWAT who put the price tag on.Just like most other BMW kit,too expensive.You can pay a lot less and get so much more.
Saw this thread and with winter coming up .........
Has no-one used an oversized RAF immersion suit with the feet cut off to allow the legs to go over the boots ? Very cheap and VERY waterproof. No insulation to speak of and no abrasion but that's what layering is all about, n'est pas ?
Probably even better for off-roading as you can get hosed down much more easily.
