Protects your laptop or tablet with .25" thick foam padding.

The Cache is a protective laptop or tablet sleeve that's available in many sizes. It's designed to protect your device against scrapes and scratches and can be used on its own inside of any bag or clipped securely inside of our Cadet and Empire Builder briefcases, Synapse 25, Synapse 19, Brain Bag and Smart Alec backpacks and Tri-Star and Pilot travel bags, transforming them into checkpoint-friendly laptop bags.

The Cache protects your laptop or tablet with little bulk added and is ideal for those who don't want their device case to make their loads heavier or to take up a lot of space. It cradles your device in .25" / 6 mm thick foam padding laminated with an exterior of heavy-duty polyester knit and an interior of brushed tricot. With no noisy Velcro® or zipper, the Cache closes by simply tucking a generous flap into the top opening.

Want help figuring out which size of Cache you need for your laptop or tablet? Use our handy Laptop and Tablet Fit Guide or Here's something worth noting: the Cache is designed to be a snug fit for just a laptop or tablet. If you use a thin plastic case on your device, we suggest you measure your device with the case on to determine (or help us determine) if you need to order the next size up of Cache.

On the back (or bottom, depending how you look at it) of the Cache are two parallel "rails" of 1" wide, lightweight nylon webbing which extend from the top to the bottom. (Note: the Cache tablet sizes iPad Mini, Tablet 121, Tablet 131, Tablet 194 and Tablet 198 do not have rails.)

Included with the Cache are two removable Gatekeeper Rail Clips. To attach the Cache to one of our larger bags with the compatible rail loops (Synapse 25, Synapse 19, Brain Bag, Smart Alec, Tri-Star, Cadet), simply unclip the side of the Gatekeeper Rail Clip that isn't clipped to the Cache, slip it through the webbing rail loops in the larger bag's main main compartment, and flip it shut. Slip the Cache inside the larger bag, and pull it back out: you'll see that the Gatekeeper Rail Clips ride the rails of the Cache, allowing you to remove your laptop from the larger bag entirely while it is still encased in the protective Cache. Here's a handy video we made all about it. 

Doing this at the airport security checkpoint means the X-ray machines (and TSA personnel) will have a clear, unobstructed view of your laptop — allowing you to keep your laptop in the Cache and the whole affair securely held together as one unit. (We think that's much better than having to remove the laptop and dump it in one of those buckets.)

Most of us will appreciate this functionality on a daily basis as well: the rail system can be a convenient and quick way to remove one's laptop from the bag.

The Cache: Checkpoint Friendly

The Cache meets TSA (Transportation Security Administration) "checkpoint friendly" guidelines for laptop bags, so you need not send your laptop through airport security X-ray machines unprotected. The Cache allows the TSA a clear, unobstructed X-ray view of your laptop in the bag.

Measure your laptop (or Google its make, model, and the word “dimensions” to find its listed dimensions).
Compare its measurements with the chart to the left (swap the Height and Width when measuring for a Vertical oriented Cache).

Lifetime Guarantee

You can expect your TOM BIHN bag to give you years of hard service. Our bags are guaranteed to be free from defects in materials and workmanship for the life of the bag. That means if something goes wrong and it's our fault, we'll fix it at no charge.

Defects in materials or workmanship are uncommon and are most often evident while your bag is still new. Keep in mind that daypacks and briefcases are often subject to serious wear in everyday use. We often see TOM BIHN bags that are still solid and in use after five, ten, fifteen, even twenty or twenty-five years, with minor repairs needed here or there. But remember: only true love lasts forever.
