How it's built

Ten summers in,
still drum-tight.

Diamond Nose + Parallel Rails

Wide diamond-shaped nose maximizes plan area on small waves. Parallel rails extend the effective rail length so you carry speed through small sections that flush other boards.

Rounded-Square Tail

Narrow rounded-square tail snaps rail-to-rail with minimal energy loss. Reads inputs cleanly, transitions smooth, and holds line through quick maneuvers.

Armalight Hand-Shaped

Hand-shaped in Eagle, Idaho. Armalight composite construction handles river-rock contact better than fiberglass. Years of rocker-and-rail iteration on the namesake Montrose wave.

The Joyride is by far the best board I have ever owned. I feel completely at ease in the ocean waves or the shallow waters of the mangroves.

β˜…β˜…β˜…β˜…β˜…

The Hydrus Paradise tracks and glides very well for an inflatable paddle board. It's easy to sprint between 5-6 mph on flat water.

This board is extremely stable and handles the water like no other. Payette lake is notorious for its waves and wind.

It's fast, and surprisingly stable once I got used to the narrower profile. The quality has been fantastic.

We love this thing. Half the time we're using it as an inflatable dock at the lake that we can jump off of or just relax on.

Super stiff and stable, tracks really well and has more maneuverability than I'd have expected for its size. The material and build looks bombproof.

Quick Answers

Common Questions About This Board.

The Montrose Hyper is tuned for small to medium waves. It performs at smaller wave sizes that typically demand a much larger board. On head-high or larger, you might prefer the Enzo or Cake for the extra drive.
The Montrose's small-wave specialty is forgiving for newer surfers, but the rail-to-rail quickness rewards experienced inputs. Beginners benefit more from the Cake or Blisscuit. Intermediate-and-up paddlers love the Montrose.
Montrose, Colorado has a small standing wave that's perfect for testing rocker and tail shapes. Years of test sessions there shaped the final Hyper geometry. Many riders paddle their Montrose at totally different rivers and report similar results.
