Introducing the ALTA21

Posted by The PNW (Creator)

Hi Backers,

We’ve missed you!

It’s been a while since we last spoke but we've been hard at work designing a new backpack - one with enhanced features you guys requested! 

Over the past 6 months, we’ve been prototyping and testing new features with some of you guys to create a new and improved backpack. We think the new features will give the new backpack a more versatile function from what we've seen. Introducing The ALTA21. Check out the awesome video we made on our campaign

What's new with ALTA21? 

We made a few improvements and modifications to give the ALTA21 more features that give the bag more functionality. We kept the 100% waterproof feature (of course), improved the sternum straps and waist straps. The ALTA21 has more storage compartments but is smaller in total capacity than the S2S - a 21L pack. 

Our 2 favorite new features are the detachable Hip pack and the inflatable back support. (You can read about all the features on our new Kickstarter Campaign

Detachable Hip Pack - The top portion of the bag detaches from the pack for when you only need the essentials. Without the top portion, your Alta21 stills function as a completely waterproof backpack secured with a roll top closure. 

Inflatable Back Support - Only available for Kickstarter Backers, the inflatable back support allows for a more structured and comfortable wear. The inflatable pad is designed to also be a seat cushion.

Hydration Storage Compartment - We also added a compartment for a hydration pack. We know you all were asking for this!

Who is Arkadia? 

The Cascade mountains (Cascadia) are our testing grounds, our backyard that gives us the inspiration to create these amazing products. Our backyard lies in the Arc that the Cascade mountain range forms. It felt natural to transition to a more encompassing name that would pay homage to our roots. We are excited to start this new journey with you as we evolve our brand to Arkadia Supply Co.


You believed in us from day 1 and we wouldn't be here without you and we hope to create more things together in the future! Help us bring ALTA21 to life and let us go on more adventures! 


See you out there! 

The Arkadia Team

      Don’t buy from this creator they product quality was not good and they change the warranty policy.

      Hey Sam! It's $5 shipping to Australia so that's probably why it's coming up as $74!

      @Luis. You're going to love it!

      Hi Guys, loved the first pack.
      I tried choosing the $69 early bird which I thought said over 200 left but it keeps taking me to $74 payment.
      Are there any Early Birds left, I’m in Australia so limited to what I can spend with conversion.
      Thanks Sam
