Lightweight, easy to use, completely non-toxic, and with unmatched ease of movement, Glacier Tek Cool Vests are the perfect solution to overheating that many surgeons and operating room staff face. Each vest includes a set of GlacierPacks manufactured to stay cool for up to two and a half hours in 100°F with some users reporting up to four hours of cooling in their operating room conditions. The reusable packs recharge in ice water and are ready for reuse in 20 minutes. The vest itself is washable or disposable (depending on variety), and the cooling packs are easy to sanitize.
