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.

How It Is Made
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.
Climate neutral fabric
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.

Reducing our carbon footprint
We are carbon neutral under PAS2060 and offset our Scope 1, Scope 2 and Scope 3 operations and transport emissions. We recognise that offsetting is not part of the solution but a point to pass through on a journey to Net Zero. Carbon Neutral is just a step in that journey.
We have joined the Science Based Targets Initiative which sets independent targets for us to achieve to do our bit to limit global warming to 1.5°C. Our targets are to halve our Scope 1 and Scope 2 emissions by 2025 based on 2018 base year and reduce our total carbon intesnity by 15% every year to achieve genuine net zero by 2050.
