Here's an interesting thread about the tamron being used for aviation.
JDThomas: Instead of these over-priced "photography" bags I usually buy tactical military bags designed for weapons. They are highly padded, ultra-durable, and about 1/3 of the price that these photo bag companies charge.
I could buy these in bulk sell them at twice the price and still come in way under what these companies charge for a product of lesser quality.
That surplus bag sure looks ugly.
