I went through 8, yep thats eight, Orvis battenkill bags before i made the Tumi plunge.
My biggest thing was durability followed by something that i could easily recognize. I found a blue color for sale on their site and I've been VERY impressed. Its lasted a year already and I'm looking at a larger one.
