Steri-Strips for the first aid kit

 

Steri-Strips, a cross between a band-aid and a suture, are narrow strips of super strong first aid tape that really stick to skin and are used to close cuts in place of a suture.  3M makes them, so you know the adhesive is good stuff.

They're inexpensive, weigh nothing, and could save the day if you need to care for a substantial cut in the backcountry. Consider adding them to your first aid kit.  Get them at better stocked pharmacies and medical supply stores, and through the usual online retailers.
