To the mountains, to Brno, and on a plane ✈️
The modular and hybrid Boundary Supply Errant backpack is a 24L backpack with smart organization, durability, and an excellent price-to-performance ratio. It’s ideal for everyday carry as well as extended weekend trips.
Material and Design
The backpack is made from durable 400D nylon fabric with a water-resistant finish. It features a minimalist design with clean lines and the Boundary Supply logo on the front. It’s available in black, navy blue, and olive.
Exterior Features
The backpack has a comfortable top handle and padded shoulder straps. The straps are ergonomically shaped and breathable, making it comfortable to carry even for longer periods. On the sides, there are compression straps that can be used to secure water bottles or a tripod.
On the front, you’ll find a zippered pocket with an internal organizer for small items such as keys, a wallet, or a phone.
Interior Space
The main compartment features a large zip opening that allows easy access to your gear. Inside, there is a padded sleeve for a laptop up to 15" and a dedicated tablet pocket. You’ll also find several smaller zip pockets and an organizer for cards, pens, business cards (if anyone still uses those), and other everyday essentials (keys, phone, glasses).
There’s also a hidden zip pocket on the back panel, ideal for storing valuables such as your passport or wallet (or even a snack).
Durability and Testing
The Boundary Supply Errant backpack has been tested in demanding conditions and proved to be highly durable. The material is resistant to both water and abrasion. The zippers are from YKK, known as some of the highest-quality zippers in the world.
In short, it will easily handle even a demanding hike around Brno.
Pros and Cons
Pros:
- Smart organization: plenty of pockets and compartments to keep your gear in order
- Durable material: tough fabric with a water-resistant finish
- Comfortable carry: ergonomic and breathable shoulder straps
- Great value for money: a lot of performance for a reasonable price
Cons:
- No sternum strap: it would help stabilize the backpack while walking or running – a bit of a missed opportunity
- Slower access to the main compartment: the large zip opening takes a bit more time to open, but you get used to it
Conclusion
The Boundary Supply Errant is a great choice for anyone looking for a durable and well-designed backpack for everyday use and short trips. If you want a backpack that will last for years, this one won’t disappoint.
Thanks to a wide range of accessories, you can also customize it to fit your specific needs.
And don’t forget – you can return the backpack within 14 days. But we believe that once you unpack it, you won’t want to let go of it or take it off your back.
