These are available for sale once again... From CNOC I'm unaware of any friends having one? After seeing reviews stateside, I yearned to try one. I searched high and low, from back packing outfitters, survival stores and hardware stores a cross the world. The only one I could find was in Canada and cost $65 Cad plus shipping and tax!!! I received an email from Cnoc yesterday...... They're back in stock £23 shipped.... At that price, they should be without tax?? If your not familiar They weigh in at 2oz/57g so only a tics sac less than my sawyer micro. So why another filter? 3g less, and with the benefits of having caps over both ends, so no more dribbles in the storage pouch or need for one. So that's another weight saving. They seem to be very popular amongst US backpackers and are reputed to have a superior flow rate to the sawyers. For a fastpacking... The hook was set. I've ordered one along with they're 2019 3L bag for using as clean water storage on extended camps with the wife. I'm looking forward to comparing it with my micro and will review it initially and again after a couple of months use.
