This Lowepro compact Toploader has closed-cell foam protection, plus an AW Cover. The "AW" designation of the Lowepro Toploader 65 AW indicates "All Weather". Lowepro includes a rain coat that pulls out of a pouch underneath to provide water protection.
A generous front pocket organizes the small stuff and simplifies film and filter changes. A belt slot lets you slide the bag onto your belt. Optional Chest Harness and Cinch Straps are available.
The smallest in the Toploader series, the Lowepro Toploader 65 AW accommodates smaller professional SLRs with a shorter lens, such as a 17-35mm f/2.8. The bag can be used with the supplied shoulder belt, or simply slide an (optional) S & F Deluxe Waistbelt or your own belt through the Toploader's back belt slot. The optional Chest Harness can also be used with this bag.
The size of the Lowepro Toploader 65 AW accommodates a DSLR body and a lens up to and snuggly including the Canon EF 24-70mm f/2.8 L USM Lens with the hood mounted reversed. The fit is really tight with the 24-70 L and an EOS 1-Series camera body, but the zippers will close (I leave the neck strap hang out). The Canon EF 28-135mm f/3.5-5.6 IS USM Lens will fit without a problem.
A front pouch snuggly holds a Canon 420EX Speedlite Flash or other similar-sized items. A zippered pouch under the zippered top holds small things like CompactFlash cards, lens cleaning cloths ...
There are SlipLock slots on each side of the case to accommodate 2 additional Lowepro cases such as Lowepro Lens Cases.
