The Axis Whitewater board is built for all-around moving water use.  
Since its creation in 2022 by designers and shapers Jason and Nick Zawadzki, it has quickly been adopted and revered by many as the best all-around river use board. 

Day Trips / Expeditions / Camping Trips / River Running / Surfing / Freestyle and slalom

The weight limit on this board is over 300 lbs, so there is a lot of stability even with all your gear tied down.

Our boards are factory pressure tested at 31psi, so you are more than safe using your board at the maximum recommended 20psi. 

Most riders choose between 10-15psi depending on the situation and personal preference.  Due to the materials that create a stiffer board, there isn't much of an advantage to inflating over 15psi.  

*The Axis was independently tested, and out of 49 premium boards, the Axis took the honor of the #1 stiffest inflatable surfboard in the world.  Our JoyRide model was #2.

Quick Note About Sales

A quick note about how we operate and uniquely handle sales: 

Tales of our obsessive attention to detail, ultra-high quality, "treat customers as we'd want to be treated," service, and "more for your money" value took off, and we are selling out of our small batches of boards, way faster than expected.  Please jump on the waitlist if a board isn’t currently in stock.  We are careful about updating our website, so if a product says in stock, grab it.  If it's a pre-sale, we are building more and near completion, so buy now and get the sale price. If it's out of stock, get on the waitlist, and we'll notify you ASAP; it's on a first-come, first-serve basis. 

As many of you know, Hydrus is dedicated to delivering the highest quality products directly to customers at outstanding prices.  We can use more expensive materials and higher-quality construction by building small batches and keeping our operations as efficient and low-cost as possible.  

We refuse to overspend on advertising, paid reviews, ridiculous chain store mark-ups, marketing gimmicks, or any other nonsense that ultimately costs our beloved customers and supporters time and money. Instead, we believe in delivering the best gear and letting our customers and supporters spread the word. 

30-Day Guarantee

30-day promise

So long as the item purchased doesn't show abnormal signs of wear and tear, and it's within 30-days of your purchase receipt and/or delievery reciept, we will offer you the choice of a 100% refund or 110% in-store credit towards a different product of your choice.  Customer may be responsible for return shipping fees.

Hydrus Inflatable Difference

We take the extra time and effort to build our boards better.  From the materials we use, and the unique features and accessories that come with each board.  

Our inflatable boards are designed, shaped and engineered by people that paddle A LOT!!  Unlike most inflatable boards you see these are not cookie cutter designs and shapes pushed by a lot of marketing dollars.

You can see and feel the difference right away. 

  • New Composite reinforced, triple layer Fusion PVC shell.
  • Newly engineered triple layer fusion seams. Better than the average "welded seam" in several ways. 
  • Woven drop-stitch 
  • The only Limited Lifetime Warranty in paddleboards.
  • 30-Day Money Back Guarantee.
  • 2% of all profits go towards supporting our lakes, rivers and forests through foundations like American Whitewater and Outdoor Outreach. 
Our Story and Pricing

Started in 2013, by two brothers a few close friends, and the dream to build small batches of premium boards with fresh ideas, responsible manufacturing, and a customer-friendly approach.  


We are a local co. just outside of Boise, Idaho, a city surrounded by beautiful lakes and rivers. Hydrus is quickly becoming known for personal service, extreme durability, new ideas, clean looks and our premium products.

Full StarFull StarFull StarFull StarFull Star“River surfing is hard on equipment, and this board has hit rocks a ton of times. Its durability is unmatched...” -Derek D.  Owner of a Revo SUP and ToughBlade Paddle


In typical Hydrus fashion, we take a new approach to sales.  A Community Direct approach. We promote all that make our sport and community stronger. Referrals are the most authentic sales.   We spend very little on marketing but instead rely on word-of-mouth and the quality of our products.  Then, we give back to those who support us by way of the best service possible.

Over the last few years, we've invented Armalight Construction, CrossBoards, composite re-inforced iSUP’s, Tough Blade Paddles and boards that are strong and durable enough to give then a Limited Lifetime Warranty.

From the beginning we’ve had a different mission for Hydrus.   We are all about supporting the sports we love and our community!  Our boards may be some of the most expensive to build in the world but we find ways to make sure our prices are more than reasonable.   Straight forward with no gimmicks, no overblown marketing budget, responsible manufacturing with almost zero waste, nearly everything done in-house and our main source of sales is referrals then we pass the savings on to you.   

We do a lot of R&D, design 100% of every product ourselves, and we maintain quality that’s far superior.

Thank you for the support!!!
