Thanks. I bought the ProTactic 250. Super bag but a bit snug if you intend to carry more gear. I'm thinking to upgrade to the ProTactic 350
Canes76, I bought the Lowepro Tahoe BP 150 backpack on a special at a local retailer. Very happy - more than enough space, and still compact with good protection. The only thing missing is a sleeve the right size for my iPhone 6...The interior of the bag is made from a material very like the fluffy side of Velcro (the "loop" material) so you can easily make your own dividers and retaining straps with Velcro. Good buy IMHO.
