Waterproof Protection for Your Dreadnought Acoustic Guitar!

SKB's iSeries Waterproof Acoustic Guitar Case offers military-strength protection to your prized dreadnought acoustic guitar. Following in the footsteps of SKB's wildly successful MIL-Spec waterproof cases, this portable guitar vault won't just keep out moisture, it'll keep out a flood! This SKB hardshell case is made of ultra-high-strength polypropylene copolymer resin and built to last. It shrugs off impact, humidity, and changes in pressure. Built-in wheels and a comfortable, snap-down-rubber over molded-cushion-grip handle also mean the SKB iSeries Waterproof Acoustic Guitar Case makes breezy work of storing, transporting, and protecting your Dreadnought-shaped 6-string — Sweetwater's gigging guitarists can confirm!

Note: This hardshell case was designed for use with most dreadnought guitars. Please contact your Sweetwater Sales Engineer with any questions or concerns regarding compatibility.

Reality-proof construction built to withstand the abuses of air travel

If you fly often, then you already know how hard air travel can be on your gear. This SKB iSeries case perfect for protecting your favorite dreadnought acoustic guitar from the hazards of air travel. In addition to being waterproof, the hardshell case is virtually "airproof" too. Its injection molded, high-strength polypropylene copolymer resin shell can shrug off scrapes and bumps like no other hardshell case on the market. What's more, even the best built hardshell guitar case won't travel well, unless it's TSA approved. Fortunately, this case also features TSA-approved locking latches so both your guitar and your case will arrive in one piece.

A perfectly regulated vault for your dreadnought acoustic guitar

Thanks to its gasketed, waterproof, and airtight seals, your Dreadnought is preserved by the case's ability to maintain its own independent internal pressure. That means even if you're flying, you don't have to worry about the extreme change in altitude affecting your guitar. In fact, this SKB iSeries case meets the US military's strict regulations for moisture and pressure resistance, even qualifying as waterproof under full immersion. Simply put: your acoustic guitar couldn't be safer than it is in an SKB iSeries waterproof hardshell case.

Convenient comforts onboard

Like every SKB case, the practical perks of this iSeries entry aren't all there are to offer. In addition to being a truly elegant case that's worthy of even the highest-end acoustic guitars, it also offers significant onboard features that make traveling with your guitar comfortable and easy. Built-in wheels allow you to trail it behind you as you rush from the car to the gig, or the terminal to the gate. The hardshell case also features extremely comfortable handles, whose cushioned grips feature snap down rubber coverings. Cushioned handles may seem like a small bonus, but when you been lugging around a case for hours, you'll sure be glad you have them!

Reviews

Travel Guitar Case
I was glad I had purchased the guitar case. I Was flying across country on American Airlines. There was a young man who tried to and bring his guitar on board using a soft case. They made him check it and it went under the plane. I've heard some horror stories about broken necks and other damages. I was taking a 1974 D28 Martin and didn't want to chance. Thanks Paul Lee for your expertise.

Best case ever
I bought this case for travel with my 1949 Martin D-18. I wanted something that would protect it and this case does that and more! Carry handles from three sides, wheels for easy transportation, and plenty of room inside for instrument cables, straps, pedals and more. The best part is I have peace of mind that my guitar is safe.

Best Travel Case Period
I bought this case several weeks ago for my Taylor acoustic guitar, knowing that I was traveling soon. My salesman, Mark Bruhn told me about the extensive testing that SKB performed on this particular product. Submerging it in water, standing on it, dropping it, etc. When the case arrived I immediately put my 314ce in it to check the fit. As promised, it was a perfect fit, and fit snugly around the entirety of the instrument. On the day of my flight I checked the case in with the agent, albeit a little nervous about how my guitar would fare. Upon arrival to baggage claim and claiming the case, I opened it up checked for any issues. Not only was the guitar fine, it was still in tune! The case truly delivers on its ability to protect your guitar. Thanks Mark!
Perfect fit for my Gibson Hummingbird
This case is a perfect fit for my Gibson Hummingbird. Checked the case for my flight and the guitar made it safely to the gig and back home.
