BIG TURTLE SPECTRA is a special version of Trail Bum's signature backpack, upgraded with highly durable SPECTRA ripstop nylon.
It retains the clean, drawstring-bag-inspired construction and light, body-hugging carry of the original BIG TURTLE while providing greater resistance to abrasion and impact.
With a versatile capacity of 13-19L, it works well for everyday use, cycling, day hikes, overnight stays in mountain huts, and SUL-style overnight trips. Its simplicity makes it easy to use for years, while its understated design fits naturally into almost any environment.

BIG TURTLE SPECTRA may quickly become the backpack you reach for more often than any other.
Although its main capacity is relatively compact, the large front mesh pocket adds plenty of practical storage. Rainwear, bottles, snacks, and other frequently used items can be packed and accessed easily during a ride or hike.
Even with a light load, the slim body remains stable against the back, while the wide shoulder straps distribute pressure comfortably across the shoulders. The lightweight yet durable SPECTRA fabric also makes it easy to use without hesitation, whether in the city or on the trail.
It is an excellent first ultralight backpack, as well as a highly capable daypack for hikers who already enjoy a lightweight approach.
💬 STAFF REVIEW
BIG TURTLE is the backpack that stays with me for around 300 days of the year. I carry it to work, around town, and on everyday bike rides. It also works perfectly as a backup bag for longer rides and bike camping trips.
Its versatile 13-19L capacity fits naturally into my daily routine without ever feeling like too much. Of all the backpacks I own, this is probably the one I use most often, and it remains one of my absolute favorites.
