Butler Creek Featherlight Slings are the first in the industry to be made of a lightweight foam, which is 45% lighter than the Butler Creek Quick Carry Padded sling. They also offer breathability with the cut out slots to reduce trapped heat as well as grip the shoulder better. The soft on the shoulder foam also adds comfort, providing all day wearability while being secure on the shoulder with a large thumb loop attached to the bottom of the sling. Adjustable from 22 to over 36 long and 3 wide. Large thumb loop to secure sling on shoulder while navigating rough terrain.
