Crowded stations and busy sidewalks bump a bag around, and the Pelican SXH5 Aegis Protective Sling answers with Pelican Shield, a durable EVA molded front shell. Cordura fabric and YKK zippers make up the rest of the pack, and internal organization keeps small items sorted. What Our Gearhead(R) Experts Are Saying:"On brisk walks with plenty of stairs, I clipped on the removable chest strap, and the sling stayed put against my body. The shoulder and waist straps carried comfortably, and the slide release buckles made it simple to take off at my destination."
