We have MOLLE waist packs on sale for $9.25 with the option to upgrade to brand new ones for just a few dollars more. These packs are very versatile as the video above shows- they have a built in belt to be worn around the waist or as a
shoulder bag as well as MOLLE straps so you can hook them on a vest or pack. They make a good case for a first aid kit, fishing bag, tool kit or anything else you want to grab and go with. A poncho liner will go in one with room to spare is you stuff right, so you can put a poncho liner in it with a rolled poncho strapped to the top and some 550 cord and have a grab and go shelter kit.
