  1. ‘Perfect Things’, Outside Magazine Buyer’s Guide, Summer 2018

    Packing this submersible protective case means less stress about valuables and electronics when dealing with monsoons, sketchy boat rides, and loose water-bottle lids. Contents remain visible, which is great for consulting maps in damp conditions, and the shoulder strap allows important documents to remain accessible at border crossings.

  2. Tanya Burton, Kenya Expedition

    This was a Life saver. I used the Aquapac Large Whanganui to keep all my paper work protected whilst doing the project work at Shimba Hills Nature Reserve. Was also great for storing the GPS and mobile phone. Even with having it over my shoulder whilst walking through the bushes it remained in tack. This is ready to use for my next expedition.
