{"product_id":"2145368-en-techniche-techkewl-phase-change-cooling-back-wrap-lxl","title":"TechNiche TECHKEWL Phase Change Cooling Back Wrap, L\/XL","description":"TechNiche TECHKEWL Phase Change Cooling Back Wrap is a safe alternative to an ice pack. Ice packs are often too cold to be next to skin and can cause frostbite and vasoconstriction. Placing a barrier between the skin and ice pack reduces effectiveness. The Back Wrap will maintain a constant 14 C (58 F) for up to 3 hours and does not rely on evaporative cooling to function. Activation is accomplished by placing the Universal Pad into a fridge, freezer, ice water or in any environment below 14 C (58 F) for 25-30 minutes. The Pads will turn white from clear when they are recharged. The Back Wrap is great for targeted cooling of the back with a comfortably cold pad.","brand":"techniche","offers":[{"title":"apparel_colour_17683:Opaque White|apparel_size_20350:L\/XL","offer_id":19665385029701,"sku":"2145368","price":72.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0036\/4806\/1509\/files\/5aa6d7dfdf259f6bb37ae63ea5183642612480be_square2145368_1.jpg?v=1764842039","url":"https:\/\/www.staples.ca\/products\/2145368-en-techniche-techkewl-phase-change-cooling-back-wrap-lxl","provider":"Staples","version":"1.0","type":"link"}
