Our 15 Fathoms official logo t-shirt is the hallmark of our company. Named after the first shot, or 90 feet of anchor chain, 15 Fathoms is not only a nod to all mariners and ocean lovers, but is the part of the anchor chain which sits deepest in the water, preventing ships from coming out of moor during heavy seas. 15 Fathoms logo is internationally recognized as a symbol that unifies divers and ocean lovers all around the globe. Let us be part of your adventure. Submerged we are one.
