After a bit of trial and error the weight pocket has been a game changer. Ideal for a 1kg dive weight, this provides a far more graceful entrance to any prospective user. Humans and dogs alike would get annoyed with swimming up to the Stern Sling and it being floating on the surface making it difficult to access. This little pocket keeps your sling in place for elegant return to the boat. Our test pilots, Moki and Coco, think these are great.
