National Geographic Earth Explorer Review Round-Up
Most of us won’t ever get an assignment from National Geographic, but this huge, rugged, well-built khaki bag will hold enough gear for self-styled photo treks to slot canyons or the Serengeti. It has a dedicate laptop slot, and its top and bottom compartments can be joined by unzipping the divider panel to haul seriously long glass. In a category in which ballistic nylon is the standard, these safari-style bags stand out from the pack. READ FULL REVIEW AT POPPHOTO

This big, rugged bag can accommodate lots of big gear, including both a 17-inch laptop and a 400mm f/2.8 supertele. That space and weatherproof construction make it a good choice for hardcore sports and adventure photographers, and photojournalists too. The new Vertex even features silent zippers, for times when even the slightest noise might spook a skittish wildlife subject, set off an avalanche, or annoy a VIP on the podium. 
Backpacking to a remote location to get the pictures you want can be hungry and thirsty work, and that’s why you’d be wise to carry your gear in this new model from M-Rock. It holds a small laptop, D-SLR with 70-200mm f/2.8 (or similar size) lens, some compact zooms, and accessories — with room left over for water. A flat 200ml water pouch with a drinking tube is incorporated into the bag, making it easier for you to stay hydrated while hiking. And when you get hungry, you don’t even have to take off the bag; just get your sandwich out of the Extreme Zion’s integrated lunch cooler. If you want to haul more gear and less food, just pop the cooler out. About $150. 
The Lowepro Slingshot 100 AW is currently the smallest of the Slingshot models. Characteristic of a sling type of case is the single padded and liberally adjustable shoulder strap that goes over the head and hangs on a shoulder. The Slingshots are designed to hang from the right shoulder. An additional strap and clip under the right arm optionally secure the case while it is in the on-the-back position. A handle is provided for carrying the Slingshot off-the-shoulder. The AW portion of the product name refers to the “All Weather” protection provided by a just-the-right-size rain jacket stored under the padded section of the back of the case and held in place by hook-and-loop fastener. Pull it out when needed. The rain jacket is of course for the case – not you. ? ?The Lowepro Slingshot 100 AW pads and the case itself are very protective – very typical for Lowepro gear. Quality construction is also typical Lowepro. The external material is a strong, durable Nylon. The case itself is very light. ? ?The Lowepro Slingshot 100 AW is comfortable to carry even when fully loaded (the small size does not allow a too-burdensome load to be created). Your back is treated to a thick pad that very adequately insulates your body from the camera body. The small case size makes it easy to navigate forests and crowds of people while wearing the pack. Accessing the camera is fast and easy – the case works as designed. There is not much room for fingers to hook onto the grip of the 30D body with the lid only partially opened (as is typical for quick access in the field). I didn’t find this to be a big problem, but a little more room would be welcomed and would make access easier for a 20D/30D/40D class DSLR.
