Osier Belle has introduced a new range calle Osier Belle SHIELD. It is a process applied to a selection of popular fabrics available in our range that provide a barrier underneath the fabric to make them fully waterproof. It does not change the feel of the fabric. For details which fabrics are available with this additional protection, please go to our Materials page (link) and hover over the fabric name. Osier Belel SHIELD will appear in the description. All other fabrics are water-repellent. These are absolutely suitable for fully exposed areas but will let in moisture in heavy downpours, however, all Osier Belle cushions have been specifically designed for the extremities and will dry 100% without any concerns.
