This fly wallet is ideal for the minimalist wading angler. Because it is form fitting it easily fits in ones waders (or pack) and eliminates getting poked in the ribs by stiff space consuming plastic fly boxes. This is the largest fly wallet you'll find and can hold streamers up to 12". This durable wallet is made of heavy-duty 1000 denier cordura, faux sherpa ewe fleece with velcro closures. There is nothing on this wallet that can brake, corrode or mildew. It just holds flies, not moisture. Machine washable (cold water, air dry). Made in USA.
