The Alpkit Kuoka bar roll is well made in the UK from a natural looking eco fabric with great long term aftersales back-up. It’s not fully waterproof but it’s weatherproof enough for most days and so far it’s lasting well. Pricing is good for the quality and back up, too.
Double ended opening makes the Koaka easy to force feed it bulky items and drag them out again. The mounting straps are also compression straps so you can squash it/roll it down as compact as possible. The new fabric has a nice soft feel and trad look coated in a DWR (Durable Water Repellent) coating that most weather rolls off without soaking into.
