Protects your laptop or tablet with .25" thick foam padding; securely clips or fits in many of our backpacks, briefcases, and travel bags. 

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.

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.  Note: if you have a plastic protective case on your laptop, you'll need to order the next size up of Cache. Want help with that?, give us a call, or live chat with us.

The Cache features a #5 YKK coil zipper with two plastic sliders: important because the plastic won’t scratch your device. The zipper wraps around two of its four sides, allowing the Cache to work well in both portrait and landscape orientations. The zipper opens at the top (shortest side) for use in vertically-oriented bags like backpacks, but also zips open on its widest side when in use in horizontally-oriented bags like briefcases and messenger bags.

The Cache can be used in any bag; when you pair a Cache with one of our backpacks, travel bags or briefcases that has rail loops, the Cache becomes part of a clever checkpoint-friendly protective laptop solution. Here’s how it works:

On both sides of the Cache are two parallel "rails" of 1" wide, lightweight nylon webbing (exception: Size 08A iPad Mini is just too small to have rails) which extend from the top to the bottom. One side of the Cache has vertical rails while the other side of the Cache has horizontal rails; this, plus the clever zipper opening, allows you to conveniently use and secure the same Cache in our briefcases and backpacks.

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 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 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. 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.

Curious which sizes of Cache fit in our various travel bags, backpacks, and briefcases? Go to the page of the bag you’re wondering about — for example, the Synapse 25 — and look at the sizes of Cache offered in the drop-down menu under 'Add a Size of Cache'.  Only the sizes of Cache that fit the Synapse 25 will be listed.

Depending of course on the size of Cache, it will securely clip in the following bags:
Cadet, Daylight Briefcase, and Empire Builder briefcases
Synapse 19, Synapse 25, and Brain Bag backpacks
Tri-Star, Western Flyer, Stowaway and Pilot travel bags

The Cache fits (but doesn’t clip) in the following bags:
Maker’s Bag, Parental Unit, Medium Cafe Bag, and Small Cafe Bag messenger bags
Daylight Backpack, Guide's Pack and Hero's Journey backpacks
Pop Tote and Swift tote bags
Aeronaut 45, Aeronaut 30, and Co-Pilot travel bags

And, of course, as long as it’ll fit, you can use the Cache in a non-TOM BIHN bag.

Here's a handy list that displays the size of Cache needed for some popular devices. Don't see your device on this list? and we'd be happy to help you choose a size.

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.
