Reviewed by Stuart Reid (Manchester) - 15th Jul, 2017Staff review Perfectly Protected & Easy To Use A simple but effective way to keep all your goods dry and isolated in your bag. No matter how much rain or snow you might face on the hill these will provide space to keep some dry warm gloves and other clothing plus digital equipment like a camera inside your bag with the elements getting to it and I personally found the 22L perfect to fit into an 18L bag by the time I had rolled the top down and packed around the Dry Sack. I used these once and now I have the full set. Great to see in a store with help from an assistant. You wont look back.
