Description

We present for your use these optional, removable internal frames with aluminum stays for the Aeronaut 30 and Aeronaut 45 travel bags.

We’ve pre-bent the stay to a generic spinal curve; if you'd like, you can re-bend and/or adjust the curvature to best fit your own back (see here for video instructions demonstrating how to do this with the Guide's Pack frames; the same method applies to the Aeronaut frames).

Please note: Aeronaut 45s made before 2014 have a slightly shorter back compartment, which means you'll need to use the Aeronaut 30 Internal Frame. If the main compartment dividers of your Aeronaut 45 are secured with snaps as opposed to zippers, you have an Aeronaut 45 made before 2014.

In doubt as to which vintage of Aeronaut you have? emailus@tombihn.com or give us a call at 1-800-729-9607 or +1-206-652-4123.

Benefits of an Internal Frame

On bags with a webbing or padded hip belt, the vertical stability facilitated by an internal frame with an aluminum stay can help to lift some of the pack’s weight onto one's hips.
It creates a hard back panel that prevents less-than-carefully packed objects like a thermos or DSLR from poking one in the back.
It can prevent an overstuffed bag from barreling out against one's back.
To some folks, a rigid frame against their back (with padding between the frame and their pack) just feels right.

Why You Might not Want to Use a Frame

A frame adds weight to a bag. Our Aeronaut 45 Internal Frame weighs 9.9 ounces / 280 grams and our Aeronaut 30 Internal Frame weighs 8.6 ounces / 245 grams. In many cases, you can forego the frame and achieve similar benefits with careful and thoughtful packing: carry less stuff, carry lighter stuff, and arrange it all carefully so it doesn’t poke into your back.
Soft luggage has myriad advantages over rigid luggage, and an internal frame converts the Aeronaut into a bag that's somewhere in-between soft and rigid luggage. The rigidity offered by the internal frame could become a liability when you’re squeezing your pack into the baggage sizer, in the overhead compartment or under the seat in front of you. That's a reason it's nice to be able to remove the internal frame when you want to.
Some folks simply prefer the feeling of a frameless or soft-back pack.

Aeronaut 45 even fits the FILBE Assault Pack very well
I was looking for an improved framesheet replacement for my FILBE assault packs. I wanted something with protected edges because the originals tend to eat themselves through the fabric over time and something with a support bar to have a better weight distribution.
After checking weight, how it fits and how it feels I am very happy with my purchase. The new framesheet weighs even 13 to 15 grams lesser than the original framesheets (180 grams vs. 193/195 grams). Sizewise the new framesheet is almost the same as the originals, only ca. 3cm lesser in height (see the attached photos). The Tom Bihn framesheet has a short aluminum bar that helps forward weight to the hips. The shape and holes seem to do what Tom Bihn claims in the product description.
Overall I can definitely recommend this Tom Bihn framesheet as an improved replacement for the FILBE assault pack.

Gamechanger for my A45
I loved my Aeronaut 45 before, and appreciated its softsided-ness, but adding the internal frame instantly gave my bag a spine, giving it a sturdiness that somehow made my A45 feel even more substantial and more predictable when hanging from a strap off my shoulder.

Exactly what I needed
I was having trouble with my bag collapsing when I used it as a backpack. Adding this internal frame fixed the problem.

Love the internal frame!
Changes the quality of the carry in my Aeronaut 45 so it’s more comfortable carrying heavier weight.
