Core 1.7 Sling
CORE 1.7 — Built for movement. Refined for everyday.
The Core 1.7 Sling is TUFA’s evolution of the cross-body carry — clean, compact, and cut from Ultra200X in six limited colorways. Designed for quick transitions between trail, travel, and town, it rides close and flexes with your motion whether you wear it front or back.
A compact cross-body carry, cut and sewn in Montana. 1.7 liters, three compartments, built from Ultra200X — Challenge Sailcloth’s strongest fabric for its weight, with enough structure to hold shape empty or loaded.
Two Styles
Winged — the original. Integrated wings hold the bag against the body. The stable option for waist carry and active movement — running, scrambling, riding.
Modular — removable strap, dual tab system. Side tabs orient the bag cross-body. Vertical tabs shift it to a low side carry, worn over the shoulder — or mount it to shoulder straps and pack interiors with compatible hardware. Without the strap, it functions as a standalone pouch. Less contact with the body, more airflow — suited to hot, humid climates.
Fabric
Ultra200X, in six limited colorways. Limited to five yards of each color.
Interior
Three compartments — main, phone, utility — with key clip. YKK AquaGuard zippers.
