Officially, the Dive Rite Insulated Regulator Bag is here to protect your regulators from bumps and bangs in transit. Unofficially, somebody at Dive Rite clearly had the post-dive deco beverage in mind. The insulated 15L body keeps whatever is inside protected, an OPV valve on the outside lets it vent, and a zippered pocket handles the small stuff like mouthpieces, tools or a bottle opener. Use it for regs, use it for drinks, or do both on the same trip. We will not judge.
