Fast fuel, no faff
No more rooting through panniers or unpacking the kitchen to find your mid-morning peanut butter bar. Stem Cell mounts neatly between your bars and stem to keep fuel, flasks, gloves or camera within easy grabbing distance. The single-hand cinch cord lets you open and close it on the move even one-handed and fully gloved.

Stays put. Rides smooth.
With webbing ladders for adjustable strap positions and foam reinforcement to keep its shape, Stem Cell stays stable across rough terrain and through full bikepacking loads. It comfortably fits a 750ml water bottle or our MytiMug 650 with the drawcord extended, freeing up your frame bottle cages for other uses.

Weather-resistant and built to last
Constructed with X-Pac X11 a rugged, waterproof laminate with a 100% organic cotton outer and recycled polyester X-PLY backer Stem Cell handles rough weather with ease. The 500D Cordura base is tough, abrasion-resistant and ready for thousands of trail miles. Its sewn in our UK factory and made to last a lifetime.

Lower impact. Higher miles.
X-Pac X11 is one of our lowest-impact technical fabrics, cutting virgin plastic and fossil fuel use with its organic cotton and recycled construction. While the outer fabric is waterproof, seams arent taped so we recommend dry bags for electronics or important items when riding into serious weather.
