Tom Bihn Aviator Travel Sling Review: A 1.5L Sling That Gets Travel Right

Introduction

Finding a sling that genuinely works for travel is harder than it sounds. You want something small and lightweight, but still large enough to hold what you need for a full day out. The Tom Bihn Aviator Travel Sling manages that balance well. After a week of testing, it checked every box on my list for a small travel sling, and it made me reconsider a few assumptions about the brand along the way.

Who This Sling Is For

At 1.5 liters, the Aviator sits firmly in the small-sling category. It is not designed to swallow a water bottle or a jacket, but it excels at carrying the small items that actually clutter your pockets while traveling: electronics, cables, sunglasses, a wallet, earbuds, a travel adapter. If your day bag needs are modest but real, this size is close to ideal.

Build Quality

Tom Bihn has long been underrated on quality for the price, and the Aviator continues that pattern. The bag uses ripstop nylon fabric, large number eight YKK zippers, a thick durable nylon webbing strap, and a large Duraflex buckle. These are the kind of details that matter over years of use rather than days.

The same construction philosophy shows up across the lineup, and the Navigator has quietly become one of my favorite travel backpacks as a result. If you like how the Aviator is built, that backpack is worth a look too.

Organization: Three Pockets That Earn Their Space

The front external pocket sticks out from the bag and has its own volume, taking up roughly a third of the sling’s total space. Packed full, it holds a surprising amount of gear; left empty, it lays flat and keeps the profile slim. There are no further dividers inside, but a long keychain with a metal clip gives you a secure spot for keys.

The second external pocket sits on the back, partly hidden behind a fabric flap. It occupies the same footprint as the front pocket but is much thinner, with no standalone volume. That makes it the natural home for flat items like a notebook or a travel wallet.

The Main Compartment

The main compartment accounts for most of the bag’s volume and strikes a sensible balance between organization and open space. A separator sleeve on the back wall has a little stretch to it, while the front wall holds a stretchy mesh pocket plus a small zippered pocket. Crucially, all of these lay flat when empty, so they never eat into the usable space.

That leaves a generous open area for whatever you want to stuff in, which is exactly what you want in a small bag where every liter counts.

Carry and Strap System

The carry system is deliberately simple: a thick nylon webbing strap in a closed loop, adjustable through the buckle with no dangling straps. You set the length once and wear the sling around your waist, across your front, or slung over your back. It works comfortably in any orientation, which is a small thing that pays off every day on the road.

What Actually Fits Inside

To test capacity, I loaded a compact handheld gimbal into the main compartment, with room left on top for odds and ends and plenty of space remaining in the front pocket. A battery pack and charging cord went into the main compartment as well, and a notebook or travel wallet fit perfectly in the thin rear pocket. Even packed like this, the bag was full without being overstuffed.

Swap the gimbal for smaller items like sunglasses, earbuds, or a travel adapter and the Aviator comfortably covers a full day of travel essentials, though bulkier items like a water bottle or a jacket remain out of reach.

Buying Advice

If you need a dedicated day sling for travel, one that carries electronics and small gear without bulk, the Aviator is an easy recommendation. Look elsewhere if you need to carry water or layers, but for the 1.5-liter use case this is a well-built, thoughtfully organized option that should hold up for years.

Conclusion

The Tom Bihn Aviator Travel Sling nails the fundamentals: the right size for a small travel sling, quality materials and hardware, smart organization that never gets in the way, and a simple strap system that adapts to however you want to wear it. For travelers who want a compact, dependable bag for daily essentials, it checks all the boxes.
