Petaluma, California – Camelbak has developed the Quick Stow Chill Flask, which it claims is the first insulated collapsible bottle. This, and the companion non-insulated Quick Stow Flask, feature leak-proof polyurethane reservoir materials.
The bottles were designed for runners and cyclists, after feedback indicated current products that can be flattened for storage were too soft or limp to be easily carried, even when full.
The Chill flask includes a layer of insulating foam between two layers of polyurethane reservoir material, doubling the time the contents stay cold. Both bottles have a 500ml capacity, and feature a self-sealing leak-proof valve in the lid. They are due to reach the market in October.
