For a basic first aid kit with the essentials, I bought mine at Walmart. by the time you get everything individually your saving a lot of money buying a kit. Then you can add some of the things you think you'll need. I added two ace bandages and a couple of military style large wound bandages. For survival gear that is dependent upon where your hunting as to what would be needed. My daypack normally has a 50' length of 500 lb test rope, 1-2 days of food, usually mre's and lots of energy bars like granola and the sort. My camelback holds enough water for 2-3 days, extra knives and sharpener. Oh and if I know I'm not going back to the truck during the day I'll bring my msr stove and coffee press. Makes for a full daypack but I can honestly say that I'd rather have it and not need it then need it and not have it.
