The Crossbone is the slimmest in the 3%Tactical rear support bag line up.
 
The fill ratio and fill itself on The Crossbone is totally adjustable to the shooters preference.
 
All rear support bags are fitted with a webbing loop, so that the shooter can attach it to his/her backpack when hiking through the bush or between stages at a competition.
 
This is the ideal bag for the minimalist.
