This is a replacement for the Lycra Back Panel that currently ships with all Arc style backpacks. It creates a trampoline with an air gap against the wearer's back. It is also compatible with all older Arc backpacks as a retrofit.

The Lycra mesh is soft and stretchy and feels good on the wearer's back.

We also have our original style Mesh Back Panels which are made with pocket mesh. Some customers prefer the original style mesh because it is more firm, and has better airflow. Either style are interchangeable on all old or new Arc backpacks.

This is our original style Mesh Back Panel. It is used to add tension to our Arc style backpack frames, and to help maintain a gap for air flow against your back.

This will fit all Arc style backpacks, and can be retrofitted on old or new packs. It is made form our 3.5 oz/sqyd (119 g/m²) pocket mesh. The holes are a little larger than 1/8" (about 4 mm) and they allow very good airflow.

This mesh doesn't stretch as much as the Lycra Back Panels that are currently shipped on all Arc packs. Some customers prefer the more firm pocket mesh, and increased airflow compared to Lycra. Other customers prefer the more soft and stretchy Lycra that is now our default.
