For travelers trying to stay light on time and fuss, Travelon Toiletry Sheets are a great alternative to lugging three-oz. bottles of your products. Each plastic pouch contains 50 biodegradable sheets of shampoo, conditioner, hand soap, body wash, shaving lotion, or laundry soap. Just grab a sheet and add water and–presto! Instant cleanliness. Exploding and leaking bottles in your luggage are so 2008. I especially like the option to do tiny amounts of laundry with a sheet of soap rather than carrying a pouch of dry detergent on the road in far-flung locations. Each pack of 50 costs $9.95, so it’s about 20 cents each time you shampoo, which is not too cheap–but the cost of not zip-locking all those 3-oz. bottles is just about priceless.
