SIS offer a superior range of trusted sports nutrition products designed to help you prepare, perform and effectively recover from exercise or endurance.  Considering a 2% loss in hydration through sweating can result in a 10% loss in performance, correct hydration and nutrition are vital for the active body.


At Countryside Ski & Climb we offer a comprehensive range to suit your needs whether competing or to correctly rehydrate from a bottle or backpack. It is a common misconception that water alone is enough to hydrate so next time you are considering a long day out in the UK somewhere check out SIS rather than just choccy bars and a tea-stop to give you a helping hand.


Products coming soon

The Countryside Ski & Climb team are in the process of adding new products to our website every day. But in the true spirit of the outdoors adding products is very much like climbing a mountain, it's further than it looks, it's higher than it looks and it's harder than it looks.

We will be adding to each of the categories and brands on a regular basis but if there is something you specifically want in the mean time, please either visit our comprehensively stocked Stevenage Old Town store, telephone or send us an email with your query. We will endeavour to respond immediately.
