Originally issued to protect and compress the USMC 3-Season Sleeping Bag and Bivy Cover, this dry bag integrates seamlessly into the ILBE rucksack system or any commercial backpacking setup.\u003c\/p\u003e\n\n\u003cp\u003eConstructed from durable 210-denier nylon with high-frequency seam-welded construction, this sack provides total waterproof security. It features a classic roll-down top with a secure buckle closure. What sets this bag apart from standard dry bags is its built-in one-way air purge valve. This allows you to forcefully expel trapped air without letting water in. Combined with the integrated vertical compression straps, you can shrink down bulky clothing and sleeping bags to a fraction of their original size, maximizing the space in your pack.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features \u0026amp; Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNSN:\u003c\/strong\u003e 8465-01-574-4003\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Coyote Brown\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e SealLine (Cascade Designs)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heavy-duty, waterproof 210-denier nylon with seam-welded construction\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e Approximately 27\" Height x 7.5\" Width (unrolled)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 8 oz (0.5 lbs)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eClosure:\u003c\/strong\u003e Roll-top seal with quick-release buckle\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCompression:\u003c\/strong\u003e Features a hands-free air purge valve and durable webbing compression straps to minimize bulk\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Genuine US Military Issue (USMC), Made in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIdeal Uses:\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003eBackpacking and hiking in wet climates\u003c\/li\u003e\n    \u003cli\u003eKayaking, canoeing, and overlanding\u003c\/li\u003e\n    \u003cli\u003eCompressing bulky sleeping bags and cold-weather clothing\u003c\/li\u003e\n    \u003cli\u003eBug-out bags and emergency preparedness kits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNote on Condition:\u003c\/strong\u003e Please select your desired condition from the dropdown menu.
