Riding a bike, skying and sailing made my wardrobe diverse, say the least.
I use a lot of riding gear on the water and on the snow fields as well. Dianese riding gloves, BMW summer pants and bib and brace are my favorites.
Base layers are the same for all sports, no cotton stuff, only wool or nylons. Use a lot of Paddy Pallin gear.
Sharkskin or sealskin are excellent. More layers, the better.
Take with you a lot of spare stuff, if you get wet you'll need it.
Use Helly Hansen gear as well but not too good.
Sleeping bag, goose down with sprayproof outer cover, -15 ? grade.
I only buy good quality gear regardless of price.
Head light is red and white, low and high, flashing or steady Petzl Tikka XP2.
Seasickness? Never heard of it.
