Review on Ultra-Lightweight Waterproof Bag Set - 5 Pack Dry Sack Waterproof Stuff Sacks with Airtight Sealing, Ideal for Backpacking, Kayaking, Camping, Boating, Beach - Includes 2L, 4L, 6L, 8L, and 10L Waterproof Bags. by Mark Jefferson

I got these in black because I use them to attach gear to/in my pack for 72 hours. A get-to-safety package I don't want to draw undue attention to. The different sizes help distinguish the contents of the subsets (e.g. fire, food, medical, water-sensitive clothing) without having to open individual bags for inspection. In situations where I may need to act quickly without much warning, I find this compartmentalized approach very useful. Suitcase (which I will use to pack my other gear) will keep your gear 'tons' protected from both the weather and prying eyes. Light weight, low cost and great support for my purposes make these waterproof dry carry bags a big deal in my emergency preparedness. I hope you found my photos and comments useful to think about a product that I am happy to recommend.
