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. We think the rail system is 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:
CadetDaylight Briefcase, and Empire Builder briefcases
Synapse 19Synapse 25, and Brain Bag backpacks
Tri-StarWestern FlyerStowaway and Pilot travel bags

The Cache fits (but doesn’t clip) in the following bags:
Maker’s BagParental UnitMedium Cafe Bag, and Small Cafe Bag messenger bags
Daylight BackpackGuide's Pack and Hero's Journey backpacks
Pop Tote and Swift tote bags
Aeronaut 45Aeronaut 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 dimensions of every Cache. Have any questions about what will fit? and we'd be happy to help you choose a size.

    I miss the old envelope design

    Fits my Cadet perfectly, further extending the life of an excellent bag.

    Only wish it used to old envelope-flap design, which I found SO MUCH EASIER to get the computer in to and out of.

    Zippers make sense for some people, but not especially for me. Ahh, well.

    (please excuse cat hair in picture - my old Cache has become a favorite perch)

    Suspension for your tech

    This cache fits perfectly and I love it. I have three of them for my 12.9" iPad Pro, 13" MacBook Pro with Touchbar, and 14" M1 MacBook Pro. The cache itself is padded and provides a tight, but perfect, fit for each device. The straps allow for a clip in to my Cadet and allow for easy access while securing it in the bad for travel. I would buy one of these for any device I planned to travel with.

    Nice, but doesn't fit MacBook Air so well

    Nice sleeve, and good quality, but it's a little too big for the 2022 MacBook Air--even though it says it's compatible.

    Protection for my M2 MacBook Air

    It's the right size and ample protection. It fits right in to larger bags like my Large Cafe Bag and my Maker's Bag. And the rails come into play when I put it in my Synik 30. I couldn't be more satisfied.

    Doesn't fit Macbook Pro 16"

    I was disappointed after waiting for a long time for a cache for the 16" Macbook Pro. Unfortunately it didn't fit - it was impossible to zip it up. Customer support was great, they sent me another one with a return label in case it didn't fit, and it didn't so I had to return it.

    I don't think my MBP 16 is larger than typical so i'm assuming it's the tolerances on the product that are not working.

    Hey Matt! I'm really sorry that Cache isn't a good fit for you! I just sent you an email to figure out what we can do to make this better. -Mike

Sewn in Seattle

Our bags are designed and sewn right here in Seattle, Washington, U.S.A.

That allows us to be control freaks in the best way possible; we have direct control and oversight of the quality of our materials, our products, and the jobs and working environment that we help create. It also offers us a unique spontaneity: when we have an idea for a new product or accessory, we can design it, figure out how to build it, add it to our website and be ready to ship it out our front door all within just a few weeks. How cool is that?
