The wife and I took a recent trip to Disney World.  The weather forecast was for rain during much of our visit, so we decided to purchase a couple of messenger-type backpacks for the trip to hold umbrellas, rain ponchos and snacks.  The strap pocket for the cell phone on this pack had no closure and my cell phone slid out of it a couple of times, so we switched packs and I used the one purchased for my wife, the Yen's SB-6826.  This pack had a zippered pocket with a mesh inner lining for the phone and we didn't have to worry about losing the phone.  The largest zippered opening was slightly shorter than the zipper on the 6BP-05 and our large umbrella wouldn't fit inside of the Urban pack.  Both packs were comfortable to carry and not a nuisance like larger packs we've used in the past.  One drawback for both packs is the shoulder strap is made from from slick material and so the pack would constantly keep sliding off our shoulders.  It would be nice if there was some type of non-slip material on the shoulder strap.
