Use this Harrison JUMBO Film Changing Tent for those 70mm 1000' mags, or if you just like the extra room, this bag works great for IMAX, Panavision and Movicam 1000' mags. Folds up easily into its own stuff sack. Made in USA by Camera Essentials.
New Storage Recommendations for all Harrison Tents and Bags
Store your Harrison Tent loosely (unrolled) in a cardboard box or paper bag. If you have silica packets, you can put them in the box with the Tent. Use the stuff sack for travel only. The Fabric needs to "breathe" when it's stored for a long time. Don't store in an area with extreme temperature variations (ie. car trunk, garage). This can damage the fabric over time.
