Their boards. Their water. Their words.
Photos from Hydrus owners across the lineup. Their boards. Their words. Their water.

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.

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.

I message the company and received a phone call from Jason (the man himself) a few hours later.

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.

First trip out was down Silver Springs to see manatee, river otter, blue tilapia, and so much other wildlife.

I have had 4 Hydrus hard boards and the Axis 8'8" is my 1st inflatable from them. It feels unlike any other iSUP I have tried.

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.

Angela and Jason made the whole process of buying my Hydrus Axis an absolute pleasure from first contact to my board arriving.

I bought it because I was looking for something durable for my size (6'4", 300lbs). I have to say I am extremely happy with it.

If you're on the fence about this board, do yourself a favor. I have not fallen off this board even while paddling in wavy and rough ocean waters.

I upgraded to this board from an Atoll 11'. This board tracks really well and feels firm and stable underfoot.

We discussed other options including the JoyRide, but based on my input and background Jason recommended the Paradise and I could not be happier.

First iSUP I've owned and it's phenomenal. I spent over 40 hours researching various boards and was referred to Hydrus by a reputable blogger.

INCREDIBLE board. Super stable with speed too. Don't hesitate. I can't imagine any other brand being remotely close to Hydrus.

The Paradise is so fast and fun but still stable. I'm a beginner and had no issues standing up and staying on.

I finally have my Hydrus Axis 98! By far the best river paddle board. Indestructible frame and so effective in the rapids.

I knew this board was going to be good but after receiving it I was blown away. The color, style, stability and speed are fantastic.

After trying many different boards this one was recommended to me and I'll never own another. The quality and performance is unmatched.
