They feature a zipper closure and a Velcro webbing on the lid
Gary Engvall of Cranston, RI has designed two great compression bags to hold all of your Premier lobsters, fish and other cool soft kites. They feature a zipper closure and a Velcro webbing on the lid to hold the end of a kite's bridles to prevent tangling. The compression part of the bags are handled by quick release buckles for fast release and opening. The buckles also make it fast and easy to compress the contents.
