Rambo Optimo Liners fit exclusively with the Rambo Optimo Turnout, allowing you to adjust the warmth of your blanket to suit every change in weather. The liner attaches to the Optimo shell at the neck and tail cord. This prevents layering with stable blankets and having multiple straps and buckles. When you use the Optimo Liner, you have only the surcingles and chest fastener of the outer blanket to unhook.
