Ok, here is what I can remember:
Pack - Lightwave Ultrahike 70l
Sleeping Bag - Rab Neutrino Endurance 800
Tent - Hilleberg Akto + pegs
Pad - A Multimat one similar to a full length Thermarest Prolite (going to upgrade to an Neoair X-therm or similar)
Cooking - Ti 500ml pan, 30ml Speedster burner, Ti spoon, lighter, Aluminium windscreen/pot rest + base from Speedster Stoves, fuel in 250ml bottle (not full)
Sleeping clothes - 200g/m2 top and long johns + wool socks
Hygiene - toothbrush, travel toothpaste, 2x tissue packets, lighter, ~25ml alcohol gel, lip balm, ~30ml hand cream
Food - ~1.5kg for dinner, breakfast and 2 x lunches
Magazine
Head torch - small, not sure what brand (mostly for reading, to keep my emergency day walk one fully charged).
Pack liner - 2x rubble sacks
Winter mountain day stuff:
Berghaus Deluge over trousers
Bergans Superlett jacket
Alpkit Heiko Primaloft Silver (60g/m2)
Keela belay jacket Primaloft Gold (133g/m2)
Fleece hat
Softshell gloves
Buffalo pile mitts
Extremities overmitts (I don't like this glove system and will update when the current ones wear out)
Fleece buff (for covering face in case of severe wind + hail or spindrift)
ME mittens (spares in case of others wetting or blowing away)
Ski goggles
Map + A5 case
Compass
FAK
2x 500ml Nalgenes (the pockets on my pack are too small for 1 larger bottle)
Bothy bag (brought because I was leaving the tent low down)
Head torch - Black Diamond Storm
With the kit above, I would plan to camp low down and then just take the day walk stuff to the summit/ridge/plateau or whatever. I'd aim for the day stuff to cope with full on winter conditions e.g. Cairngorm plateau (to use a bit of a cliche) - hence the extra gloves, extra insulation etc. Obviously, ice axe and crampons would be part of the kit in those conditions.
Anyhow...I'm interested to hear people's (more experienced) opinions.
