WaterField Designs has introduces the Staad, a new backpack designed “to flow easily from causal to professional office environments. Its stream-lined exterior and organized interior snugly secure a laptop and an iPad or tablet plus accessories.

A World War II-era buckle — once used to instantly access ammunition — can be opened with a “quick flick.” Padded interior pockets keep a laptop and tablet secure and the main compartment organized, while angled, zippered, side pockets stash small necessities like keys and an iPhone 5s. A quick-grab leather handle provides an additional carrying option.

Neoprene cushioning and moisture-wicking material keep the wearer comfortable and dry, says Gary Waterfield, founder of Waterfield Designs. The Staad BackPack is available in two sizes: slim (US$319) and stout ($329). For more info go to http://tinyurl.com/ltcpmdu .
