Our verdict
The NRS Neutron is the brand’s most whitewater capable packraft. The open-decked self-bailer comes with both a cargo fly and thigh straps, making it multi-day whitewater-adventure ready from the start.
At 38” wide, it’s the widest whitewater packraft we’ve tested and the width added some stability without sacrificing too much turning and handling, making it ideal for newer to intermediate packrafters to take on some bigger Class III rapids. The Neutron uses a proprietary valve with a locking nozzle that makes it incompatible with other companies’ inflation bags or pumps without a special attachment.
Our testers used this on a multi-day, variable Class II trip in Chiapas, Mexico, where they encountered lower-flow, creeky, winding waters up to big full Class II drops. Our testers there noted: “I kinda got attached to this packraft, even though it's the fattest I’ve used. Once you get into a rhythm, it’s easy to maneuver. It handles a rough ride in creeky waters and rocks like a champ!”
We also tested it at the Clear Creek Whitewater Park in Golden, CO, and at Gross Reservoir in Boulder County, CO. It bounced through the rapids in the whitewater park with relative ease in early summer conditions (2025) and tracked well for a wider whitewater boat—better than the Kokopeli Nirvana (37” wide), but not as well as the Alpacka Mage (34” wide). On the flatwater at Gross Reservoir the boat handled well and cut through light afternoon winds with relative ease. Given its width, we don’t think it’s ideal for tight, narrow Class III-IV rapids but on wider creek and river rapids it handles well.
NRS Neutron Packraft
We think this packraft is a solid option for novice to intermediate packrafters who aren’t afraid to take on some whitewater, and for those who don’t mind using the proprietary nozzle or buying extra attachments. It’s not as whitewater capable as the Alpacka Raft Mage or Gnarwhal, but it did track better than the Kokopelli Nirvana in testing. It’s also not as versatile as the Alpacka Raft Classic or the Caribou, which pack small and light enough to use for bikepacking and backpacking. However, it’s great that it comes with the thigh straps and cargo fly as standard, and it’s a little less expensive than the Gnarwhal.

What we liked
Tracks well
Easy to steer for a wide packraft
Though wide, moves super well in fast Class II
Thigh straps easy to adjust
What could be better
Proprietary inflation nozzle—if you lose the inflation bag or don’t have an adapter in the field, it becomes difficult to inflate. This is especially higher-stakes if you are traveling on a longer river trip with no bailout points with someone else in a raft with a different valve. Bring all your valve attachments and repair kit!
Width makes narrow, difficult rapids harder
How we tested

Our testers, both intermediate packrafters, took the NRS Neutron on multiple outings. We used it on a multiday (7-day) trip in Chiapas, Mexico on Class II and low Class III rapids. The water levels on the river were much lower than usual, making many of the narrower Class II sections fast and creeky (and sometimes dicey). That trip included portages around boulderfields where we carried the packraft. We also tested it at the Clear Creek Whitewater Park in Golden, CO and on flatwater at Gross Reservoir in Boulder County, CO.
Under normal early summer conditions at the Clear Creek Whitewater Park, it was easy to line up, pick through, and turn into and out of rapids. On the flatwater and light, windy chop at Gross Reservoir the boat handled well as we circumnavigated the coast and crossed through the middle of one the fingers of the reservoir.
We didn’t test it in a bikerafting or backpacking scenario, as its packed weight (11.86 pounds) and size (22 x 11”) would take up most of the space in a pack and be unwieldy on a bike’s handlebars or frame.
We tested the NRS Neutron alongside other packrafts in our Best Packrafts guide. If you’re looking to get into packrafting, check out our How to Get Started Packrafting video.

On-water handling and maneuverability
Despite its width, the NRS Neutron tracked and turned well while cruising across the reservoir. It didn’t feel like it wandered between paddlestrokes and responded easily to input from the paddle. The only drawback was the width meant we had to extend our paddle strokes a little farther to reach water without hitting the side of the boat.
Stability
With a wide, stable bottom, the boat handled moving water and rapids well. It doesn’t respond quite as fast as a narrower boat, however. We found when paddling this in narrow Class III rapids, you definitely need to pick and commit to your lines with confidence
Whitewater performance

Though we didn’t test this in big Class III rapids it handled all the rapids we did test it in well. We wouldn’t recommend it for Class IV and above rapids. The self-bailing worked well in rapids we rode.
Inflation and setup
With the included inflation bag, the Neutron inflated well. We also bought an adapter to use with an electric pump, which worked well. Inflation took a few minutes with the bag and a little less with the electric pump.
Packability and carrying
Packed up into a 22” x 11” roll weighing about 12 pounds, it’s a little unwieldy to carry on a bike’s handlebars or in a backpacking pack. However, it’s light enough that it’s easy to portage with it fully loaded and inflated (up to a mile or so). For instance, we had no problem portaging with this slightly bigger raft (and a dry bag and paddle) over large, slippery and wet rocky terrain. When rolled up you could carry it on the bottom of a backpack, but if stored in the backpack, you’re not going to have too much room for much else.
Cargo and gear storage

With bow and stern loops, it’s easy to rig up storage on the bow or attach a PFD when floating on flatwater, but we didn’t carry significant weight on the bow. The centered TiZip SuperSeal Comfort zipper on the stern made shoving dry bags into the hull easy. We didn’t notice the gear sliding around inside very much.
Comfort

In our testing we felt pretty comfortable with the back band and inflatable floor. The thigh straps are among the most comfortable and easiest to adjust that we’ve tested and added control to the boat. However, they didn’t provide as secure an interface with the boat as the 3 and 4-point thigh straps from Alpacka Raft.
Durability
After multiple days on rivers and creeks we didn’t notice any damage to the hull or floor. The material looks and feels much like the materials NRS uses on their larger rafts, which last for decades, with proper care.
Features

The NRS Neutron only has four options, blue or orange and standard size or XL (we tested the standard size). The standard is 7’10” long and the XL is 8’ 3”long. The cargo fly, thigh straps, back band and inflatable seat come with the boat.
Inflatable floor
The full-length, inflatable floor adds some stiffness to the packraft, helping it handle rapids. It also allows paddlers to adjust how they want to sit in the boat for their comfort and to maximize their reach with the paddle. Shorter paddlers may want to sit higher and farther forward than taller paddlers, for instance. The packraft doesn’t have a separate inflatable seat that sits atop the floor.
Back pad
On the NRS Neutron the backpad is adjustable to accommodate different sizes of paddlers and can move forward and backwards. Though not very adjustable vertically, it did a good job of supporting paddlers of different heights.
Thigh straps
We tested an early version of the boat with two-point thigh straps. They worked well when needed, but now the boat comes with three-point, padded thigh straps for adjustments up and down as well as towards the calves and upper thighs.
Cargo fly
Located in the middle, behind the paddler, the cargo fly offers access to both sides of the hull, making it easy to stow gear in drybags inside the hull and increasing stability when floating.
Stern and bow handles
The boat doesn’t come with either, but with attachment points at the bow and stern, it was easy to tie rope in to make ersatz handles.
Included blow bag
The blow bag is easy to attach to the proprietary nozzles, and the pack raft does come with a blow tube in case you lose the blow bag.
Repair kit
A small repair kit is included. It has patches for the hull and lube for the TiZip cargo fly. However, our repair kit came in a standard ziplock and we’d recommend putting it in a more burly, waterproof bag to keep it safe.
TiZip Zippers
The NRS Neutron’s TiZip cargo fly comes with a one-year warranty, while the packraft carries a three-year retail warranty.
Sustainability
NRS doesn’t discuss specific sustainable practices on their site. You can find their 2023 Impact Report and mission statements on their site, but we didn’t find anything more recent.

Similar packrafts
NRS Neutron vs Alpacka Raft Caribou
Price: Starts at $995
Type: Lightwater
Best uses: Multiday flatwater trips up to Class II
Base weight (boat only): 4.5 to 4.9 lbs
Weight with accessories: 6 to 6.9 lbs
Packed size: 6 X 17”
Weight capacity: 390 lbs
The Alpacka Raft Classic was our overall favorite packraft for its versatility, and its successor, the Caribou, seems to follow suit. Both rafts are lighter than the NRS Neutron, pack smaller for backpacking and bikepacking, and are capable in lightwater (Class II, tops). The NRS Neutron is more capable and forgiving in rapids thanks to its wide base and design.
If you’re primarily looking for a whitewater boat, the Neutron is a better choice for a pack raft, but if you’re looking for a boat of all trades, it’s still the Alpacka Classic, or its successor, the Caribou. The Caribou starts at $455 less than the Neutron and is offered with or without a cargo fly and as a sealed floor or a self-bailing floor.
Alpacka Raft Caribou
NRS Neutron vs Alpacka Raft Gnarwhal
Price: Starts at $1550
Type: Lightwater
Best uses: Multiday trips and up to Class III-IV whitewater
Base weight (boat only): 5.5 to 6.5 lbs
Weight with accessories: 8.25 to 10.4 lbs
Packed size: 9 x 22”
Weight capacity: 370 pounds
Compared to the Alpacka Raft Gnarwhal, the Neutron is bigger, burlier and wider. That means it’s a little more forgiving going into bigger rapids and it’s also a little less easy to steer in rapids and flatwater. Still, it floats and responds well for its size. The Gnarwhal also packs down a little smaller at 9” X 22” compared to the 11” X 22” size of the Neutron. Fully kitted at 10.4 lbs in the Gnarwhal’s XL configuration it’s still lighter than the fully kitted Standard option of the NRS, which weighs 12 lbs. The Gnarwhal also is offered in four sizes from Small to XL and multiple fabric weights for those who want a more durable or lightweight packraft. The Gnarwhal starts at about $100 more than the Neutron.
Alpacka Raft Gnarwhal
Neutron vs Kokopeli Nirvana
Price: Starts at $1,299
Type: Whitewater
Best uses: Multi-day floats, up to Class IV
Base weight (boat only): 7.3 lbs
Weight with accessories: 9.2 lbs
Packed size: 14 x 10”
Weight capacity: 300 lbs
The NRS Neutron handles better than the Kokopeli Nirvana that we tested. It tracks better and responds to paddle strokes better. That makes it more capable in rapids and on flatwater. The Nirvana starts at a lower price, $1,299, for a boat with a spray deck without a cargo fly (add $150) or thigh straps (add $80). Similarly equipped, the Nirvana starts at about $100 more than the NRS Neutron. The Nirvana is offered in self-bailing format as well, starting at $1,349. We’d recommend the Nirvana if you’re primarily looking for a packraft with a sprayskirt.

Why you should trust us / About the author
I first learned of packrafting around 2016. Since then I’ve used them to explore Colorado and have used them on multiple creeks, rivers, reservoirs and lakes. I’ve gone on daytrips and multiday trips—including classics like Ruby-Horsethief Canyon, and used them on self-guided and guided tours. I’ve also gone bikerafting, including with one of the pre-eminent pack rafters, Steve “Doom” Fassbinder.
As one of the first reviewers for Treeline Review, starting in 2019, I’ve covered a lot of outdoor adventure gear across multiple activities, among them hiking, camping, climbing and mountain biking. I wrote Treeline Review’s initial packraft buying guide in 2022.
Beyond my work with Treeline Review, I have authored multiple outdoor guidebooks. My most recent Falcon Guide, "Colorado’s Best Front Range Adventures: The Greatest Hiking, Climbing, Paddling and More From Denver to Colorado Springs and Fort Collins," arrived in Spring 2021. In it, I cover the region's best hiking, biking, climbing, and rafting. I’m also the author of Falcon Guide’s “Climbing Colorado's Fourteeners: From the Easiest Hikes to the Most Challenging Climbs” and edited Justin Lichter’s excellent guide to thru-hiking titled “Trail Tested: A Thru-Hiker's Guide To Ultralight Hiking And Backpacking.” This experience has helped me become a first-rate gearhead and product tester.
I have 20-plus years of exploring, hiking, backpacking, mountain biking, climbing, guiding, and playing in the wild. I worked with National Geographic and their mapping division in developing their Colorado 14ers Map Pack Bundle. I’ve written about hiking and climbing for Elevation Outdoors, including stories about Colorado 14ers and outdoor apps to boost adventures.
In addition, I’ve written columns about ultralight hiking and gear for Backpacker, gear reviews for Treeline Review, Popular Mechanics, Bicycling, Popular Science, and other publications, including Elevation Outdoors, 5280, and more.
