NRS Zephyr Review

The NRS Zephyr is a manually deployed, unisex inflatable belt PFD that comes in just one "universal" size. A type V PFD with a type III performance, it's made of polyester with a high-efficiency welded bladder and operates with a 24g CO2 canister.

Performance Comparison

Comfort

Compared to the other belt packs we tested, the Zephyr has a strap of medium width and medium softness, which we think is pretty comfortable to wear over clothes or against the skin. This latest version condenses what you're wearing by eliminating padding everywhere but directly underneath the clip. The back of the actual pack is reasonably comfortable nylon fabric, covered mainly by the large, smooth, official approval patch. Though its edges are a bit papery feeling, we mostly didn't notice it while on. The wide clip is secured to a thinly padded section that completely prevents it from ever touching the skin around your waist. An elastic loop keeps the strap tail easily out of the way no matter how you adjust it.

While paddleboarding, it's easy to forget you're even wearing this pack. However, it's rather bulky, with its large inflatable section packed into a relatively small space. For it to function properly (and be legal), you have to wear that bulky section on the front, which can get in the way of comfortably sitting down. All inflatable belts are a little awkward when worn in a seated position, both in size and their tendency to be pushed upwards as your body changes shape when seated. You can get used to this fit and feel, but inflatable belts are much better for standing activities like SUPing or sailing.

Mobility

Any PFD of this style is going to offer some pretty top-notch mobility since it just wraps around the waist and doesn't come close to your shoulders. The Zephyr also helps keep you mobile by having the pull tab for deployment located slightly off-center, so it doesn't catch between your legs. However, what makes this model a good choice for mobility is how well the inflating function works.

Wearing a PFD this low profile and specifically made only for expert swimmers, you don't expect to deploy it every time you get on the water. But you want to know it will work if and when the day comes that you need to use its inflation properties. During our testing, the Zephyr consistently proved itself to be reliable on deployment and easy to use as an inflated flotation device. It explodes into a stiff yellow vest that simply slides on over your head. Short black straps on either side help to pull the neck hole farther open to more easily put on, and there are no additional straps or adjustments to worry about after that.

Once this inflated vest is securely attached to your front, you're not going to be doing a lot of comfortable swimming. These types of PFDs are meant for expert swimmers experiencing emergency situations that exceed their swimming abilities. In this respect, we love how quickly and reliably the Zephyr inflates. It's one of the fastest we've tested, quickly becoming ready in a true emergency when you need it most. Its only downside is that because it has no additional security straps on the inflatable portion, the neck hole very small, and some of our testers had a hard time getting their heads through it, particularly when panicking and treading water.

Versatility

The most important thing to remember about every inflatable belt PFD like the Zephyr is that it's only intended for expert swimmers, and, to be legal, it must be worn on the front and armed with a CO2 canister. This definition of who can safely wear this type of PFD is limiting. It's mostly intended for paddling, though the fanny pack design might not be everyone's favorite for sit-down paddling. On a SUP, though, it's pretty awesome. Also, if you choose to wear it a little higher on your waist, you can easily rock this thing for canoeing, kayaking, sailing, or even on the pontoon or yacht.

Rearming the Zephyr is a simple process. NRS recommends purchasing the full rearming kit that includes the 24g CO2 canister, as well as a little green tab to indicate that the system is ready for use. This small plastic tab disappears when you pull the arm that deploys the airbag — that means that it joins the aquatic ecosystem as yet another small piece of trash. Pro tip: though NRS doesn't mention it in their directions, you can rearm the whole thing the same way but without using the little green plastic trash piece. It won't have a nice green "I'm ready" spot in the indicator window, but it also won't fling garbage away into the sea. In this newest version of the Zephyr, NRS went away from the 16g CO2 canister (that's easier to find and available in bulk) and went with the larger 24g CO2 canister (which is a more difficult size to find at a reasonable price). Finally, like all the inflatable PFDs we tested, there's an emergency mouth-inflate tube — though this may be difficult to operate if you find yourself in a true emergency situation.

Durability

The strap and case on the Zephyr are made of (non-ripstop) polyester, and the bladder is welded. True to what we've come to expect from an NRS product, the quality of construction is solid, and we had no issues using this PFD. Even scouring other internet reviews didn't reveal any dirt on potential failures.

The only mildly annoying thing we noticed is that the bladder and pack are supposed to be completely dry before repacking them, which just takes time. We assume this is to prevent potential yuckies picked up in wild waters from growing inside your PFD, so this seems like a reasonable step to take toward extending the life of your inflatable. And, obviously, poking a hole in the bladder renders it useless, a problem foam life vests do not face.

Value

The Zephyr isn't the cheapest inflatable we tested, but it also isn't the most expensive. We like its compromise between comfort, usability, and reliability. For the mobility and peace of mind that it brings to the table, we think it's worth the few extra bucks.

Conclusion

The NRS Zephyr is a comfortable belt when it's packed up, easy to use when deployed, and reliable to use in emergency situations. Despite not being the smallest or cheapest inflatable we tested, the Zephyr brings a great blend of comfort with the reliability of knowing it will perform admirably when you need it.
