I have several of these Tenba Bags. They were originally designed to hold video recorders, but I used them to carry photo equipment. This one is New. It never was used because the others lasted for years.
It is made of denier nylon with dense foam padding. The large inner pocket is 15" x 18" and 4" Deep, although it's flexible and will expand. It has a heavy duty zipper that zips on 3 sides. The outer front pocket is 12 3/4 x 13 inches. The adjustable shoulder strap is 2" Wide with a non-slip rubber on the inside top. It also has a 2" carry strap on the top. Contact me for more information.
You can pick up this Tenba Bag in Franklin, MA. I can meet you in the parking lot of the Franklin Police Station.
I can also ship it to you by USPS if you pay with PayPal.
