Tent: Vango Hydra 200. (Approx 13-15 years old). 3kg
Mat: old thermarest classic, 3/4 length 730g
Sleeping bag(s): one cheap 1-season bag, packs small weighs 650g. One huge, heavy Eurohike Adventure 3 bag (fills one pannier, weight 2kg).
Stove: Trangia. 25 or 27 depending whether I'm catering for anyone else or not.
The tent is relatively heavy, and doesn't pack up particularly small, but I'm very fond of it - it's quick and easy to pitch, nice and warm in the cold, doesn't get to much condensation and is very roomy for one and adequate for 2. Unlike the newer versions of the Hydra, it pitches inner first, which could be an issue in the rain, but thankfully I've never had issues.
Both sleeping bags (and an additional thermarest) were used on the "freeze your bits off" camping. In the interests of travelling a bit lighter and a lot snaller, I've just ordered a Snugpak Softie Merlin 3 to replace the Eurohike bag.
