Comfortable breathing depends almost entirely on the diameter of the airway. A narrow tube forces you to work for every breath; too wide and it becomes awkward to hold and adds dead space. We settled on a 1-inch (25 mm) internal bore after testing narrower and wider sections against ordinary resting and elevated breathing rates. At one inch, an adult can draw a full, unhurried breath through two feet of tube without any noticeable resistance.
The whole point of the snorkel is that it stays open while people are resting their weight on and around you. A soft or thin-walled tube can flatten, pinch, or collapse under a pile — exactly when you need it most. We use a rigid, pressure-rated wall thickness so the airway keeps its round cross-section under the kind of distributed load a multi-person cuddle pile actually produces. The tube should give you air, not a puzzle.
The Standard is cut to 24 inches, which clears the surface of a typical four-to-six-person pile with the mouthpiece at a comfortable position. Deeper or larger piles call for more reach; that's part of why we offer multi-packs and longer configurations for group organizers. Length is a trade-off — every extra inch adds a little dead space — so we size for the common case rather than the extreme one.
The Deluxe model is heat-formed in a single piece to produce a swept 45° bend a few inches above the mouthpiece. Forming the bend with heat rather than a glued elbow keeps the interior smooth and the bore constant through the curve, so there's no lip, ridge, or joint to disrupt airflow or trap moisture. The result angles the mouthpiece toward a face-down user while keeping the intake vertical.
Both ends are deburred and chamfered so there are no sharp edges against your lips or your cuddle partners' skin. The material is food-grade rigid PVC: inert, tasteless, and smooth-walled, which also makes it simple to rinse and air-dry between sessions. For why we chose this material specifically — including its environmental profile — see Sustainability.
