Stem Cell is a weatherproof stem-mounted bag ideal to keep frequently used items within easy reach while riding, available in 2 sizes. The draw-cord closure can be operated with one hand and, when open, creates an extension tube allowing taller bottles or stove systems to fit snugly inside. The hood provides extra weather protection when required and can be folded away into its own pocket for easier access on fair-weather rides. Stem Cell uses hard-wearing waterproof fabrics to protect your kit from all but the heaviest rain. Built to last by hand in our UK Factory with a 25-year Alpine Bond.

X-Pac® X11 fabric uses a hard-wearing 100% organic cotton face fabric. Organic cotton farming produces significantly less CO₂, uses less water and eliminates the use of harmful pesticides.
X-Pac® X11 fabric is certified by cleenTEC® as being 100% climate neutral. X11 is made from a mixture of plant-based and recycled materials and manufactured in factories using only green energy.
The Stem Cell has a DWR coating which helps it to repel water and dirt. After your ride, wipe down your bag with a damp cloth to remove dirt or use mild soap on more stubborn muck. Leave to air dry.
