Triple Aught Design Axiom (18L + 24L) Review
"Durable. Tasty. "
The Axiom pack from Triple Aught Design is a stealthy, rugged, super thoughtful daily carry that can handle heavy duty organization and bad weather.
- Available in 18 and 24L — the 18L is quite tight and a perfect smaller daily carry.
- Water resistant — outer materials are excellent at keeping moisture outside your bag.
- Nice organization — the admin pocket, quick access pocket and special “underside” pocket make for some nice organization options.
- Modular accessories available — the main compartment of the bag has some very cool modular pockets/attachments you can purchase separately.

What I like
- Stealthy, rugged and super thoughtful. Beefy, incredible construction from Triple Aught Design.
- Extremely water resistant. I day-hiked in heavy Portland rain without a rain jacket and nothing inside got wet. I felt so secure with it on.
- Great organization: front admin panel, quick access, a secret pocket underneath, main compartment, laptop compartment.
- Awesome top taco pocket and seriously thick, heavy-duty mesh inside.
- Super cushy back panel and gummy, juicy straps. Feels like a little rocket ship on your back.
- Laptop compartment has tons of padding and a rigid plastic frame. Zips on both sides.
- The X-Pac sailcloth version is probably my favorite X-Pac ever. It has a broken-down softness to it.
- Modular accessories and hidden MOLLE if you want to build it out.
Watch for
- The 18L is tight and compact. All my stuff fit, but it felt a little too small for me.
- The laptop compartment on the 18 is really made for 13" laptops. My 15" and 16" MacBook Pros only kind of fit and were a pain to get in and out.
- The quick access pocket is too tight, with a tiny zip pull.
- The front material is loud. If you want a quiet bag, look at waxed canvas.
- Load adjuster straps come really long. I'd trim them.
