First Aid/Ski survival kit
I carry two small kits with me on top of the 10 essentials. The first aid kit has nitrile gloves, band-aids, gauze, IB, bandages, triple anti-biotic, etc. The second survival kit has a flashlight, firestarter, lighter, knife, paracord, survival blanket, hand warmers, bailing wire, zip ties, voile strap, etc.
How extensive is your first aid and survival kit when skiing alone or with a small group? Do you carry a SAM splint, antihistamines, and some of the more 'esoteric' items that you see in pre-made kits? What odd item do you never leave without?
First Aid/Ski survival kit
Solo, on a day outing, 1st aid kit has a few band aids, compression bandage or abdominal pads with that vet wrap stuff, painkillers, and a samsplint. Survival kit is fire starter, 2 large garbage bags, 2 or 3 space blankets, zip ties, some duct tape, binding/boot repaired kit, siltarp, and multitool. And a means to get an SOS out.
With more folks, or for longer trips, the kits get much larger depending on the group, similar to that described by MS above, perhaps along with someone carrying a separate wound treatment kit. Largely depends on how far and for how long we will be out for.
Current training is 40hrs WFA, and will be upgrading to 80hrs in the spring.
