This is the perfect triathlon travel pack to carry everything you need for a weekend race as well as your laptop computer. A full size floor pump will fit inside with no problem. It has a floating compartment to keep clean stuff away from dirty stuff. This pack has a volume of over 4600 cu in (29” high x 15” wide x 11” deep), yet it collapses to fit within most airline carry-on dimensions if it is not too full. It has a suspended padded laptop computer sleeve inside so the computer is well protected. The padded ergo straps have two mesh cell phone/mp3 player pockets. The wetsuit compartment has a watertight zipper. The top of the pack has a compartment with a passport pocket, slots for business cards, spare change, some pens, and a sunglass/goggle pocket. The outside has a bottle holder, and an adjustable buckled transition rack strap to hang the pack. It is labeled with a nice De Soto Logo embossed between the pads on the back. Included in the price is a 17x24-inch foldable changing mat to stand or sit on.
