Product Description


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.

Handy Little BagsReview by Mongo
These bags are the handiest items you can buy. You can put loose items into the bag and then put it in a tank bag or even your pants so when you go to look for it you can find it! I just wish they made these bags in other colors so I could look for items based on the color. Great little item for the price they are an excellent item for every biker to use - ear plug storage - eye drop holder - cell phone - lip balm and the list goes on. Buy them you will like them.

Long and slim for your car gloveboxReview by Peter
This is the second time I've purchased the long and slim bag for keeping loose items together for my Subaru Outback glove box. Items like win bottle opener, travel drugs like Tylenol, Tums, pseudofed. Just right shape. My first one finally gave up the ghost when Velcro failed after many years.

useful bagReview by willliam
I use the smallest bag to carry extra foam ear plugs on long trips. It's useful for this, but a previous iteration used to have an adhesive strip which I found useful.

Large is a good sizeReview by Lance
I just received the so-called Large bag, and it's a perfect fit inside my small RKA tankbag, essentially the size of a 1qt Ziploc, my previous waterproofing strategy. Haven't tested the waterproofness yet, but the quality seems great, and I expect to use this for many years.

Solid replacement for ziplock baggiesReview by Bagman
After bouncing around the knapsack, inside the top case, plastic baggies fall apart. That won't be a problem here. Very sturdy, and appears that it can hold off water for a while. Haven't tested that yet. Would like more colors to choose from. Wish they had a little window, so I could look inside. Also a bit expensive. But unless something awful happens to it, this is the last one I'll ever have to buy.

1001 usesReview by Bayou Crier
I bout the 5" X 5" to store my CO2 capsules in for flat repair. It is the only thing durable enough to bounce around in the tail section of my bike.
