The Expedition is the ultimate do-everything, backcountry adventure boat. Higher performance than the Classic, but lighter and more packable than the Wolverine, Gnarwhal or Mage.

Optional add-ons:

  • 2 internal clip-in dry bags approximately 40L ($3/day) will keep your gear in place inside the tubes,
  • 3-point thigh straps and foot brace ($5/day) will give you greater control in whitewater
  • a 20L bow bag with liner will keep the gear you need throughout the day secure and dry ($4/day).

When in Doubt, Contact Us About Availability

Because of the variability in transit days our business model creates unique challenges for booking software and makes it difficult to display a 100% accurate availability calendar.  If the raft you want isn’t available for your desired dates, please don’t hesitate to contact us directly as it may be an error in our system.  In many cases we can also ship the day after you book and override the default 6 day transit buffer.  We highly recommend contacting us directly for groups of 4 or more as well.  Contact info: 406-272-6468 backcountrypackrafts@gmail.com  

The chart below shows our recommended size based on your sit length and the Gnarwhal’s fit profile. To determine your sit length, sit against a wall with your legs flat (wearing your preferred paddling shoes) and measure the distance from the wall to your heels. The Gnarwhal is sized for a whitewater fit, meaning that a typical paddler in the recommended size will be able to deeply bend their knees for maximum engagement in the thigh straps for the most secure high-performance fit. You can size up or down for a more performance or relaxed fit.
