This carrier is one size fits most thanks to its adjustable shoulder straps and cummerbund, ensuring a snug fit for just about every warrior’s body type. Should you find yourself on fire, trapped in a tight spot or unexpectedly going for a swim, the new ROC buckles on one shoulder strap (reversible) and either side of the cummerbund can be rapidly released in case of emergency. These also make putting on the carrier much more convenient when you are in a hurry.
