I received my new BC2 Ergon pack from Jeff Kerkove yesterday. My previous BD2 pack was suffering some ill fated flaws. Looks as if Ergon did some serious revamping for the new version. Looking forward to giving it a test run this weekend on a big ride. Lot's of room in this one with an expanding zipper option, rain cover, waterproof zippers, 6 inside pockets for easy organizing, capacity for 3 liters of water and a zippered stash pocket on the waist belt. I'm thinking of going up to East Fork and over Blackhawk to Salt Creek and back to Rico. The weather forecast looks amazing for the weekend.
