The Ice Sack is a full-body dry cold containment system developed by BHVD Labs. It uses phase-change material panels arranged in a hex-grid architecture to deliver controlled cold without water, drainage, or a dedicated tub. The system pairs with the nine-minute Neuropause protocol — a structured cold exposure sequence designed around autonomic timing rather than arbitrary duration.
Cold exposure research has produced a growing body of evidence around norepinephrine release, metabolic heat production, and autonomic habituation. The Ice Sack was designed to make that exposure repeatable, portable, and engineered — turning cold from an improvised practice into a designed system.
First shipments of the Origin Edition begin September 2026.
