Red Sky snacks are a range of potato, root, and nut snacks from Walkers. The range was introduced in the UK in April 2009 as a premium "sharing product" in the snacks category.
It is stated that Red Sky products are made from 100% natural ingredients, and that the makers "work in partnership with Cool Earth", a charity that protects endangered rainforest; Walkers make charitable donations proportionate to the number of purchases of Red Sky snacks.
