Care and Tips Use both hands! Like a lot of new things, the TIZIP WaterSeal Zipper might take a little getting used to. Open it ,as shown to the right, for far easier and faster access than can be offered by a roll-top dry bag. Try it three times...by the third, you'll have the hang of it.The Cortez' inner liner is tested to be air-tight before shipping. If a semi-rigid frame is desirable (for motorcycling or to maintain shape while hiking), blow air in the liner and seal the zipper. Make sure to vent the zipper if experiencing a significant elevation increase. Carry the Cortez using the shoulder straps or grab loop. Do not lift by the zipper pulls. |
