⭐⭐⭐⭐⭐
“Finally — a drybag that actually feels like a real backpack. I’ve hiked with it, tossed it in the river, strapped it to my board — and my gear stayed bone dry every time. The quality and fit are next-level.”
— Trevor W.
🌧️ Meet the Backpack Built for Water, Weather, and Everything In Between
You can’t control the weather, the waves, or the occasional wipeout — but you can keep your essentials 100% dry.
The Hydrus Premium Drybag Backpack combines true waterproof protection with premium hiking-pack comfort, giving you the best of both worlds: total gear safety and all-day carry comfort.
This isn’t a thin, floppy “promo” drybag — it’s a premium-grade adventure pack designed for real paddlers, explorers, and weekend wanderers who take their gear (and their adventures) seriously.
💧 Why It’s Different
| Feature | Hydrus Advantage |
|---|---|
| 100% Waterproof Interior | Airtight roll-top closure and welded seams keep every drop out — from light splashes to total submersion. |
| Exterior Waterproof Pocket | Quick-access zipper pocket for your phone, keys, or small essentials — weatherproof and splash-safe. |
| Expandable 20L Capacity | Enough space for shoes, clothes, lunch, camera gear, and more — expands for overpacking days. |
| Comfortable, Backpack-Quality Fit | Padded shoulder straps, ventilated back panel, adjustable waist + chest belts — built for real hikes, not just short carries. |
| Floatation-Ready Design | Airtight construction traps air, so the bag floats if it ever goes overboard. |
| SUP-Ready Attachment | Fits perfectly under the bungees on any Hydrus iSUP — secure, balanced, and out of the way. |

Limited Batches, Unmatched Quality We've become renowned for our obsessive attention to detail, unparalleled craftsmanship, and treating customers how we'd like to be treated. This reputation and our steadfast commitment to quality mean our limited batches often sell out sooner than expected. Here's how to secure your piece of excellence:
- In-Stock: If a product shows as in stock, it's your golden opportunity! Grab it before it's gone.
- Pre-Sale: See something listed as a pre-sale? We're close to crafting more units. Lock in your board at the sale price.
- Waitlist: Out of stock? Join the waitlist. We operate on a first-come, first-served basis, and we'll let you know when your desired board is ready.
Unwavering Commitment, Unbeatable Prices Our fans know that Hydrus stands for top-tier products at remarkable prices. How do we do it?
- Smart Manufacturing: We craft in small batches using premium materials and superior construction techniques.
- Efficient Operations: Our streamlined, low-cost operations enable us to focus on what truly matters: quality.

Welcome to Hydrus
Hydrus 30-Day Test Ride: Love It, Exchange It, or Return It
We want you to fall in love with your Hydrus gear, and we’re here to ensure it meets your expectations.
Satisfaction Guarantee
If you invest in a Hydrus board or gear and feel it doesn’t significantly enhance your experience, or if you’re not entirely content with its quality and performance, we’ll facilitate a return and issue a full refund. Your satisfaction is our sincere priority, and we’re committed to ensuring you have the proper equipment for your needs.
Easy Exchanges
Choosing the perfect board can be tricky, and we’re here to make it easy. Within 30 days of your purchase or receipt, you can exchange your board for another model in our range. Our team will work closely with you to find the best fit for your style and preferences. If your returned board is unused and in like-new condition, no restocking fee applies—you’ll only be responsible for return shipping and any price difference if applicable.
Restocking Fees for Exchanged Boards:
To maintain fairness and quality for all customers, we inspect all returned boards. If the board shows signs of use or is no longer in like-new condition, a restocking fee of 5-10% may apply. This fee helps us cover the costs associated with cleaning, refurbishing, and restocking used products. We aim to keep this process transparent and reasonable, ensuring a fair experience for everyone.
Refunds
For items returned in like-new condition within 30 days of purchase or receipt, we provide a 100% cash refund. Customers are responsible for the return shipping fee and a 15% restocking fee if the item has been used or shows unusual wear. This policy ensures we can continue offering this generous return assurance while maintaining the quality and performance of our products.
Hydrus: A Journey from Passion to Innovation
Founded in 2013 by two brothers and a close-knit group of friends, Hydrus was more than a business venture – it was a vision and a passion. A vision to craft limited editions of top-quality boards, infuse innovative ideas, pursue responsible manufacturing, and elevate customer experience to the heart of everything we do.
Located just outside Boise, Idaho, amidst the tranquil beauty of lakes and rivers, Hydrus has come to stand for personalized service, remarkable durability, inventive spirit, elegant minimalism, and the highest quality in the market.
Here's what our proud owners have to say:
- "Top-notch boards, excellent service, fair pricing, and a conscientious company!" – Tim M., JoyRide XL Inflatable owner.
- "Exceptional quality! I now own three boards and couldn't fathom opting for any other brand! Hydrus is extraordinary!!!" – Greg H., owner of two Hydrus iSUPs and an Armalight Board.
- "River surfing is demanding, and this board's resilience is second to none..." – Derek D., owner of a Revo SUP and ToughBlade Paddle.
Our approach to sales is as unique as our products. Instead of traditional methods, we embrace a Community Direct approach, investing in what strengthens our sport and community. For us, word-of-mouth and the self-evident quality of our products speak louder than advertisements. What we save on marketing, we give back through unparalleled customer service and continuous innovation.
In recent years, we've introduced cutting-edge technologies such as Armalight Construction, CrossBoards, composite reinforced iSUPs, Tough Blade Paddles, and boards robust enough to come with a Limited Lifetime Warranty.
Hydrus's mission is distinctive. We're wholeheartedly committed to promoting the sports we love and building our community. Although our boards may be among the most expensive to produce globally, we find ways to remain competitively priced. Our approach is transparent and honest, steering clear of exaggerated marketing, gimmicks, and irresponsible manufacturing. With almost everything done in-house and referrals as our primary sales channel, the savings are passed directly to you.
We believe in investing in research, designing each product ourselves, and maintaining a quality that truly stands out.
Thank you for believing in Hydrus, where your passion for paddling fuels our dedication to excellence. We're immensely grateful for your continued support and excited to participate in your water-bound adventures. Welcome to the Hydrus family! 🌊
