Feather-Craft brings out the big boys with their new "Meat Locker" fly box. This is the second "big fly" box I own. It is the FIRST to hold up to the abuse I dish out as a guide. The foam is dense and holds the flies--no, really holds them in there. The black foam on the black box gives great contrast to your flies so it is easy to see what you have. The coolest thing, in my opinion, is that the same foam is on the outside, too! This is great for drying and seeing what flies you have already used. 
"Snaps" for Feather-Craft. :)
