A battered old camelbak chaos- got it as a magazine freebie, used it massively, it’s just the perfect size and fits me beautifully. Enough that I’ve had an ebay search trawling for replacements for ages, since the first is a bit clapped out, and just bought 2 more.
Rukka goretex motorbike trousers- protective, warm and waterproof. Tough, too- most textiles are “crash and replace”, these have been down the road a couple of times and are just a bit polished and chafed.
