The Original LTT Backpack is built for travel, work, and everyday use, ready to handle demanding tech loadouts with room for everything you need. Featuring updated titanium carabiner pulls and a bonded dual layer bottom panel, it is designed for durability without compromising usability.
The tech compartment fits up to two laptops in most sizes, with a raised microsuede lined tablet sleeve, space for a handheld gaming device, and dedicated pockets for chargers, cables, and accessories. It opens wide for quick, easy access to your devices when you need them.
With 22 thoughtfully designed pockets and sleeves, your gear stays organized and within reach. The 25.5L capacity, including the main compartment we call the “bag of holding,” gives you plenty of space for daily essentials along with a dedicated water bottle sleeve.
Designed with security in mind, the backpack features a hidden RFID blocking pocket behind the back padding for valuables like your passport or cash, along with a concealed AirTag pocket for discreet tracking.

Warranty
TMB Guarantee - Limited Lifetime Warranty
We offer a Limited Lifetime Warranty that the LTT Backpack is free from manufacturing and material defects.
The Limited Lifetime Warranty is valid for the usual and customary life of the LTT Backpack. The manner in which the LTT Backpack is used directly impacts the usual and customary life of the product, as materials will deteriorate and fade over time and moving parts (such as zippers) will also wear.
The Limited Lifetime Warranty does not cover:
- damages caused by misuse, abuse, or by accident or negligence;
- damage caused by rips, cuts or tears;
- normal wear and tear (including the breakdown of materials over time);
- products purchased from unauthorized dealers;
- cosmetic damage; or
- unauthorized modification or alteration.
UPDATE DEC 9 2023: Virtual Double-layer Clause
Originally, our messaging around the backpack claimed an advertised feature of a "dual-layer bottom panel." On December 1, 2023, it was discovered that the production version of this Backpack did not include the dual-layer bottom panel. As such, we have added an additional point of coverage for bags which feature only one layer of material on the bottom panel. In the event that this single-layer bottom panel wears through under normal use, lttstore.com will provide a replacement Backpack upon return of the damaged unit. This clause does not cover:
- damages caused by misuse, abuse, negligence;
- intentional damage;
- products purchased from unauthorized dealers; or
- unauthorized modification or alteration.
In order to make a warranty claim, you must be the original purchaser of the LTT Backpack from LTTStore.com or provide a copy of the original proof of purchase.
