EXPED Schnozzel Another cool inflation aid. If you own an Exped packsack with purge valve (Shrink Bag, Shrink Bag Pro, Waterproof Compression bag or Waterproof Telecompression Bag) you can attach a Schnozzel to the valve and use the bag to inflate your Exped mat (generation 2010 onwards). Ideal for groups who can share one pump for all mats.
