I'm putting together a survival kit for the GF and me and I would like to get some ideas for a realistic, lightweight, and compact kit. I don't like to switch out a lot of gear for different trips so keep in mind that this will be a general kit for use with day hikes, weekend tent camping or backpacking trips. Something I can throw in a day pack or move to a bigger pack for backpacking and I know I'll be covered in either case. What I have so far: multi-tool 100mph tape (wrapped around an old wallet card) 550 cord whistle emergency blanket chemlight mini bic lighter magnesium fire starter cotton ball for tinder crayon spare batteries My first aid kit is a store bought kit with a couple items added. Bandaids, gauze, benedryl, aspirin, ipuprofen, sunscreen, antiseptic cream, alcohol wipes, tweezers, rubber gloves, cold pack, medical tape, basic first aid instructions, etc. Beanie cap, gloves, long sleeve base layer, rain jacket, maps and compass, steripen purifier, cathole trough, biodegradable TP, and headlamp are all carried on every outing. I'm also interested to know what you store your kit in. I was thinking about using a small dry bag but would like some more ideas for a weather proof container.
