I'd like to give a shout out to John at Borah Gear. I recent got back from an elk hunt out west using my Borah Bivy. Bivy worked fantastic. I had to make an emergency bathroom run one night and my sleeping bag zipper got hung on my bivy zipper and due to the nature of my circumstances, I didn't have time to give it any finesse. Emailed John when I got back and he repaired it free of charge and very quickly. Great guy and great company. He is also making a custom bivy for my 6 year old son.
