The Gravis Sierra purse is a classy slouch bag with a little more than a touch of hardcore. This militant looking purse is all bark and no bite; it''s 100% nylon. No critters were harmed in the making of it''s badness. It is also bigger than it looks, holding two liters of necessities. To keep all your goodies safely inside, it has a main zippered compartment which also has a magnetic closure, a rear zippered pocket and an interior zippered accessories pocket.
