Lowepro made good camera bags back in the day (they're still making them!), and this sturdy 35mm SLR-appropriate bag is ready for its next tour of duty.  Rugged nylon construction.  Woven vintage logo on reflective ribbon.  Cross-body carrying strap is adjustable.

See photos for dimensions; bag is roughly 7 1/4" h x 4 1.4" d, plenty big enough for a standard 35mm SLR setup.
