Buckle the two vertical straps together. Pull on the loose end to increase mesh tension and the separation of your pack and back. It is especially important to have a tight mesh when carrying a heavy backpack and biking.
Clip the side release buckle around backpack top straps and cinch to tighten.
Make the lower strap into the smallest size loop that allows the buckle to reach the base of your backpack lower straps.
- Position the buckle so it opens upward and away from the loop
- Pull out the prong and clamp it to the loop (on side farthest from the VentaPak)
Snap the buckle close, making sure straps are towards the bottom (hinge) and applying force as needed
- Loosen or tighten backpack straps to position backpack + VentaPak optimally on your back and ensure sufficient shoulder room.
- Pull loose ends of the vertical straps and/or loosen at the buckle to have optimal tension and separation of pack from back. When biking with a heavy backpack, for example, the tension should be maximized to keep your pack off your back.
