Described is a venting device including a flexible outer covering defining an outer surface and an inner surface, a set of helicoidal venting strips, and a set of helicoidal buffers. The outer covering has a first end and a second end and a longitudinal axis therebetween. Each venting strip is anchored to the inner surface and extends substantially between the first end and the second end and the set of venting strips is arranged substantially helicoidal and defines a set of helicoidal seams therebetween. The set of helicoidal buffers includes a buffer covering an inner opening of each seam of the set of helicoidal seams where each buffer is configured to shield the inner opening of the corresponding seam from penetration and each buffer is anchored to at least one of the outer covering and a neighbouring venting strip of the set of venting strips.
