Decent compact first aid kit - Gear Aid Ultralight & Watertight .7 First Aid Kit

This kit squeezes a good selection of first aid items into a compact package. Unlike other brands, it actually includes a usable set of tweezers (it's tiny, but it works) and a roll bandage.

It uses a fairly durable, resealable plastic bag to protect the contents. There's enough room in the bag for some minor customization of the contents.

Bottom line - I like it. It's useful for a single hiker / daytrips.
