Aerostich Ultralight Envelope Bags

These hook & loop closure bags offer ultra-durable secure storage capacity with a faster, more convenient closure than zip-lock or zippered bags and drawstring stuff sacks. Perfect inside a tank bag, backpack or saddle bag. They are tough enough to stand up to vibrational wear, abrasion and long-term expedition use. The hook & loop strip across the top is ½" wide and end-to-end secure.

The smallest size is perfect to keep earplugs clean and protected. The largest works for full-page documents and file folders. In between sizes are great for first aid kit or cooking tools, or to protect and organize electronics. The one that's long and short is great as a travel office for organizing and keeping pens, receipts, money, and miscellany all in one place inside a tank bag or travel pack. The largest one is available in both a top and side opening version in response to customer requests to expand the storage versatility and usefulness.

We've been making and selling these for more than thirty years now. We're still using some of the originals. They don't wear out. Nobody else makes anything similar, and they continue to work better than anything else for what they do. Nine size configurations and 4 fabric options to choose from:

• Original are carefully made from blue 400D Oxford weave nylon, with a highly water-resistant PU (Polyurethane) coating on the inside.
• Lightweight are sewn from a highly water-resistant 70D grey nylon material, they are tough but not as stiff as the heavier fabric of the Original bags.
• Ultralight are constructed from silky soft, ultralight black SilNylon fabric, making them super packable when not in use, and highly protective when they are.
• Traditional Waxed Cotton bags are hand-crafted from the same authentic brown waxed cotton used to make Falstaff and Cousin Jeremy riding gear and offer rugged durability, water resistance and a retro-cool authentic look.
