USMC SealLine ILBE Waterproof Pack Liner

Many people forgo one important thing when it comes to rucking all too often: What happens when it rains on your pack? Plenty bring ample rain layers to cover their body, but forget all their gear is waiting to get soaked. Have a pack cover? It might end up soaking through after as little as 15 minutes in a torrential downpour, and it's useless if the pack itself gets submerged in a lake or river. Enter the Dry bag.

These bag liners for the ILBE main bag are made by prolific manufacturer Seal Line, and are probably going to end up being that next thing you cant live without on expeditions innawoods. Simply stuff any soft goods in the bag, open the locking air valve, roll the bag up and secure it with a fastex buckle, and press all the air out. Now everything inside is completely water tight. The locking air valve allows you to keep some air in as well meaning it'll even float with all your stuff inside, and force all the air out compression sack style, like your grandma's Space Bags. 

The interior is blaze orange, which might seem strange at first but there's two great reasons: It allows you to turn it inside out and use as a safety/rescue marker, and it makes finding items way easier than digging around in the typical black or green cavern that lines most packs.

Condition Guide

Excellent

• Lightly used and well cared for.
• Perfectly functional with either minor or no cosmetic blemishes, abrasions, or other signs of use. For the ILBE Pack Liner, the excellent grade means the liners are essentially like-new.
  

Serviceable

• Gear that remains field-ready, but sports a rougher, worn aesthetic. 
• May exhibit writing and/or markings, including rank, serial numbers, etc.
• For the ILBE Pack Liner, the Serviceable condition means that a minor field repair is required on the material of the bag to bring it back to being 100% waterproof. This generally means a small (at most 1cm) cut, or pinprick hole that needs to be repaired. We've found superglue is the easiest, most durable, and most inexpensive method to fix said blemish. Once the superglue is cured the sack is usually indistinguishable from an Excellent condition pack liner.
