In reply to martinturner:
What I take:
A decent weather forecast
Phone in a waterproof bag
Map (either laminated or preferably in an indestructible sticky ortlieb map case) and compass - and a knowledge of how many paces make 100m uphill and downhill
Goggles and a balaclava for when the weather is really horrendous
A spare pair of warm mitts (not down)
A pair of reasonably solid gloves that should keep my hands pretty dry and warm for most of the day
A pair (or two) of thin liner gloves when they inevitably don't
Full waterproofs - trousers with full length zips can be put on while standing, whilst wearing crampons
Trim fitting gaiters that don't have any instep loops and no baggy material (Outdoor Research Crocs in my case)
A synthetic insulation layer for stops (voluntary or forced)
Bright head torch with spare batteries (enough for 12+ hrs light, not necessarily full strength)
Plenty of easily consumed food including a lump of something grim but calorific (used to be KMC but now halva) that has been in the bottom of the pack for the last decade
An emergency kit that contains NSAIDS, paracetamol, blister/compeed dressings, some steristrips, a clean dressing and a roller bandage, a ventolin inhaler, dental floss threaded on a needle (or a 1/0 silk suture on a handheld needle), spare straps and a couple of buckles, duck tape rolled around my walking poles, a whistle (on sternum strap) and an emergency foil bag (not blanket), and if with others a bothy bag built for 5. I'm medical so I have other stuff in there for more worrying things, but that's personal choice.
A walking axe long enough to be useful (55cm minimum) with a classic pick rather than a banana
Crampons with anti-botte plates if possible
Depending on route it might be sensible to wear a helmet... very personal choice but having seen the effects of head vs rock after small slides, if it's firm neve or ice I'd be tempted these days, more so if moving across gullies etc. No doubt some will say this is overkill, and for sure it's better (a) not to slide and (b) to arrest immediately, but there's little protection from falling debris, dropped gear, other people etc and helmets are warm or well ventilated, light and comfy these days. If "just" hillwalking on snowy rolling terrain without rocks everywhere no need, but e.g. in the Glyderau then they can make sense. Personal judgement of risk vs inconvenience but I would always wear one winter mountaineering - and the line between that and winter hillwalking is often blurred...
Also, I take the experience amassed by making stupid decisions over many years and usually getting away with it
Enjoy the winter hills - many happy days walking and climbing in Snowdonia when I lived in Shropshire and Powys. You're pretty lucky to be close by!
cheers
