Firstly.. surplusandadventure.com -
No, no, no, no, no, no! Dont touch them with a barge-pole. Terible service, constantly lied to me on the phone, didnt deliever goods, didnt refund money, I went to trading standards about these guys.
Wouldnt recommend them for the world! The worst company I have ever dealt with. Sorry about that, just dont want others getting stung.
As for the Bergan pockets with the yoke, yeah great idea, I've got it and use them as a daysack often. Unfortunatly the pockets I got for my bergan arent the right ones, and the zips are upside down for my bag
so I mostly use as a day pack, but they still function as pockets to my Bergan when I need them thanks to the four clips that all still match up ok.
