When you drop a few hundred dollars on a premium outdoor heater like the Ninja Fireside 360, protecting it from the elements becomes a real concern. The included cover, or lack thereof, often leaves you scrambling for a generic tarp that flaps in the wind and pools water. That’s where this dedicated fire pit cover steps in. It’s a straightforward accessory designed specifically for the Fireside 360, and after several weeks of use, it’s clear this isn’t a revolutionary product—but it does its job without fuss.
The cover is made from a thick, water-resistant fabric with a soft inner lining. That lining is a thoughtful touch; it prevents scratches on the metal body and the glass panels of the heater. The fit is snug, which is both a strength and a minor annoyance. On one hand, it stays put during gusty evenings—no more chasing a flapping tarp across the yard. On the other hand, getting it on and off requires a bit of effort, especially if the unit is still warm. The elastic hem helps pull it tight, but it also means you have to stretch it over the corners each time. It’s a small trade-off for a secure fit.
In real-world use, this cover shines on a covered patio. It handles morning dew, light rain, and the occasional splash from a sprinkler without a problem. The water beads up and rolls off rather than soaking through. I did notice that after a heavy downpour, a small puddle can collect on the top if the cover isn’t pulled perfectly taut—there’s a slight dip in the center. It’s not a dealbreaker, but you’ll want to give it a quick shake or tilt to drain the water before removing it. For those in regions with snow, the fabric feels sturdy enough to handle a light dusting, but I wouldn’t trust it under a foot of wet snow without additional support.
Compared to a generic rectangular cover or a universal round one, this product wins on precision. A universal cover might be cheaper and easier to find, but it’ll likely leave gaps where moisture and debris can sneak in. This one hugs every contour of the Fireside 360, including the fold-down side tables and the base. It also has a small vent near the top to allow airflow, which helps prevent condensation buildup inside—a common issue with fully sealed covers. That’s a smart engineering detail that many third-party options overlook.
However, there are a few limitations worth noting. First, the cover is only for the fire pit unit itself—it doesn’t cover the propane tank if you have a hose connected. If you leave the tank attached, you’ll need to either disconnect it or find a separate cover for the tank. Second, the fabric, while durable, is not completely waterproof in a torrential downpour. It’s water-resistant, not waterproof. For most users, that’s fine, but if you live in an area with relentless rain, you might want to double up with a tarp or store the unit indoors. Finally, the price point is a bit steep for what is essentially a piece of fabric. You’re paying for the custom fit and the Ninja branding, which might not sit well with budget-conscious buyers.
Who is this cover for? If you own a Ninja Fireside 360 and leave it outside on a deck or patio, this is a worthwhile investment. It extends the life of your heater by shielding it from UV rays, rain, and dust. It’s also great for anyone who wants a clean, neat look without the hassle of rigging up a makeshift cover. On the flip side, if you store your fire pit in a garage or shed when not in use, this cover is unnecessary. Similarly, if you’re on a tight budget and can tolerate a generic cover that does a mediocre job, you can save some money—just be prepared for a less precise fit and potential water pooling.
In practice, this cover has become a routine part of my outdoor maintenance. It takes about 30 seconds to put on, and it gives me peace of mind knowing the Fireside 360 is protected from the afternoon sun and overnight moisture. It’s not a flashy product, and it won’t change your life, but it does exactly what it claims to do. The stitching is solid, the zippers (if any) are smooth, and the material feels like it will last a few seasons. Just remember to let the unit cool down before covering it, and you’ll be fine.
If you’re comparing this to, say, a generic BBQ cover, the difference is night and day. A BBQ cover is designed for a rectangular grill, so it’s too big and sloppy for a cylindrical fire pit. It’ll flap, collect water, and might even scratch the finish. This cover is purpose-built, and that shows in the fit and finish. It’s not the cheapest option, but it’s the right one for the Fireside 360.
Ultimately, this cover is a practical accessory for a premium outdoor appliance. It has minor quirks—the tight fit, the slight water pooling, and the price—but it delivers on its core promise of protection. For anyone who wants to keep their Ninja Fireside 360 looking good and functioning well for years, this is a sensible add-on. Just don’t expect it to be indestructible; it’s a cover, not a fortress.
