    Insotect Flow Adopted by Sierra Designs for Cloud 15 Sleeping Bag

    Vancouver, BC September 13th, 2011 – Insotect Ltd. is pleased to announce that the company’s Insotect Flow insulation system will be officially adopted by Sierra Designs within their new ultra-light Cloud 15 sleeping bag.

    The adoption of Insotect Flow by Sierra Designs reflects Insotect’s growing presence as a major ingredient brand in today’s outdoor gear. Insotect Flow has quickly gained broad adoption as a staple feature within highend sleeping bags. The Cloud 15 is poised to be the lightest 15 degree sleeping bag on the market.

    Insotect Flow is an evolution in sleeping bag construction; combining the presence of vertical thermal channels (VTCs) with Insotect’s proprietary FlowGates™. By utilizing vertical channels instead of horizontal ones, the number of total channels is decreased and thus overall material weight is reduced. The vertical orientation helps facilitate heat distribution more readily from head to toe which is an advantage over traditional side to side horizontal channels. The FlowGates are placed along the vertical thermal channels to hold the down insulation in place, minimizing down-shifting.

    “We are extremely pleased to be working with Sierra Designs on a bag of this caliber. Insotect Flow provides an exciting opportunity for both companies to collaborate on bringing a great product like the Cloud 15 to market.” – Irvin Vale Akopov, Insotect Brand Manager.
