We have had some seriously indecisive weather lately, heading out for the day involves taking everything from you sun cream to your waders, thankfully the Berghaus GR20 Storm Shell Jacket is so light (278.6g size M) and packs down into such a compact space it is no bother at all to take with you, just in case. If the weather takes a turn for the worse you will be grateful to have it, packed full of features to keep you dry, it is available in sizes Small through to Extra Extra Large.
