We bought one. It was great and just right for the Eriba. BUT they do not make one with a left sided zip. I had email correspondence with them last year about this. At first I was directed to various suppliers who did not have any. Then I was told that they would be available soon. Then I was told that there were none.
I got the impression, at the time, that they had been taken by surprise. Almost as if the Chinese manufacturer had either failed to make them or had not been instructed to make them.
I see that Go Outdoors now sell their own version of these. I wonder if they have both right and left handed ones.
