Selling two vaucluse backpack ventilation systems. I tried them at home and they didn’t work well for me. These are the original ones so don’t come with the zip ties I see they’re now selling them with but they did come with a couple of Velcro strips that I’ll ship with them. Selling as a pair for $25 so I can clear out some space in my backpacking closet! Looking for someone who wants both so I can ship only once. PayPal or Venmo f&f. Shipping CONUS included.
