Granite Gear Air Compressor

No, this sack is not waterproof. It is designed to compress and organize your gear, but it will not protect your items from heavy rain or submersion, so you should still use a pack liner or dry bag if you are expecting wet conditions.

The right size depends on the loft and fill power of your sleeping bag. As a general rule, the 11L or 16L sizes work well for most standard three-season synthetic or down bags, but you should measure the compressed volume of your bag first to ensure a proper fit.

The 210D nylon is a robust, mid-weight fabric that strikes a great balance between durability and weight. It is tough enough to handle being shoved into a fully loaded pack repeatedly without tearing, while remaining light enough for ultralight backpacking.

Absolutely. While it is excellent for sleeping bags, it is also highly effective for organizing bulky clothing like puffy jackets, extra layers, or even soft camping gear that tends to take up too much room in your pack.

At 16 ounces, the Air Compressor is designed to be lightweight, though the exact weight can vary slightly by size. It is built specifically for those who prioritize saving space and keeping their pack load balanced, making the trade-off in weight well worth the gain in organization.
