You don't pick these as your only backcountry skis. Or, it is unlikely that will be the case. The K2 WayBack 80 is light, narrow, and optimized for firm snow turns. It delivers acceptable performance in powder and tough snow, but you'll want something else when those things are more common or likely. When you are going high and firm, the ultra light weight of the WayBack 80 will endear itself and leave your legs fresher for even more of what you seek.

|Pros||Light, narrow, better than you’d expect in powder and poor snow||Light, well-balanced downhill performance||Stable, damp, predictable||Inexpensive, balanced downhill performance, average weight||Solid all around downhill performance, compatible with excellent Dynafit SpeedSkins|
|Cons||Narrow, fragile||Expensive, ski “short”||Mid-weight, no real stand out performance||Ski “short”, powder skiing stability suffers at super high speed||Heavier than average|
|Bottom Line||If your tastes tilt to the high, hard, steep, and fast, you need a pair of these.||For all but the most specialized of circumstances or users, these are the best backcountry skis on the market.||There is nothing remarkable about these skis, and that is a good thing.||Well-balanced, all-around skis for the human-powered skier looking for durable and lasting value.||The Beast leans decidedly in the downhill performance direction; they are heavy by comparison and for the dimensions, but they ski better than most.|

Our Analysis and Test Results
The K2 Wayback 80 is a solid little ski. At this point in history, skis this narrow will inherently fill a small niche. You're examining this ski, hopefully, for light, fast, and high missions. There are many things it isn't suitable for, but many cool endeavors that it is perfectly suited for. We choose skis like this for giant, multi-peak days of steep ski mountaineering. We choose skis like this for multi-day ski traverses. We choose skis like this for high-tempo training on your familiar uphill tracks. When we choose skis like this, we choose the Wayback 80. Paired with light boots and bindings, there is no better ski we've tested. In the aforementioned narrow niches, the K2 Wayback 80 is our Top Pick. Its downhill performance transcends its tiny stature and light weight to deliver enjoyable (once the skier is adapted) performance in a variety of settings.
One kilogram has become a weight threshold of interest in backcountry ski gear. For both the boot and ski categories, around 1 kilogram (or roughly 2.2 pounds) is the line that divides uber ultralight "skimo" gear from more all-around kit. In the vicinity of one kilogram, again, whether boot or ski, you can get adequate downhill performance with mind-blowing uphill efficiency. Each tested K2 WayBack 80 weighs around 1090 grams. Or, for the metric-system challenged, 1.09 kg. That's about 2.4 pounds. That's less than your full, standard Nalgene 1 liter water bottle.
We're talking super light ski gear here. This year, we've enlisted the help of a new ski tester. The Wayback 80 is half the weight of anything he had used prior. He reported a significant (like, multiple days of touring) adjustment period to such light skis. These are unlike what you've used before, most likely. Your first uphill steps will be so different that you won't fully appreciate it. Your first downhill turns will take even more adjustment.
Once adjusted to the weight, though, you won't go back. The skeptical new tester just called to ask if he could use these K2 skis on an upcoming, high-consequence and committing trip to Europe. He'd choose these skis, at this feather-weight, for his only skis on an entirely different continent. That's perhaps enough endorsement. There are other skis in this weight class on the market. We've tested some. There are more similarities than there are differences within the weight class, but the K2 is our favorite in this range. They're great.
Stability at Speed
You don't pick skis like this for stability. The narrow and feathery construction will wobble and chatter more than bigger options. You can't escape that. In terms of stability, weight is a performance attribute. More weight equals more stability. And these don't weigh much, as we glowingly observe above. High speed stability suffers the most. Steep terrain stability is a slightly different story. In the steeps, the K2 Wayback 80 suffers the same low-mass issues, but the needle swings back to the plus side due to the narrow stature and super stiff construction.
Choose bigger skis if max-rate downhill skiing is your priority. With excellent technique and good snow, we are seeing our testers making slalom type turns, but not giant slalom turns, on the WayBack 80.
Of all the downhill situations you'll face in the backcountry, it is in firm snow that you experience the fewest compromises with the Wayback 80. Once your basic balance and weight distribution habits have adjusted to the mass and stature, the 80mm waist of the Wayback can be pressed to grip, carve, and turn predictably on all the flavors of hard and icy snow. As compared to big, wide, powder snow specialists, the WayBack 80 edges ahead. In those conditions (you listening, East Coast? California High Sierra? Springtime Northwest?), these narrow skis do better than skis weighing twice as much.
When you can win-win like that, with something as inherently as compromised as backcountry ski gear, we recommend you do so. In virtually all ski performance situations, weight is bad going uphill but good going downhill. Greater width brings greater weight. With the K2 WayBack 80 and firm or corn snow conditions, as compared to bigger, trendier, heavier skis, you can get super light weight and better downhill performance. Movers and shakers in the business, who have been watching trends for decades, note a few things.
Skis have gotten wider over the decades. BC skiing has gotten more crowded. The High Sierra of California (known for firmer snow) has "suffered" a smaller increase in crowding than other regions. It is one tester's opinion that the apparently declining appeal of that firmer terrain is due to gear trends. People try out firmer backcountry skiing, on their heavy and soft-snow optimized BC ski gear, and don't like it. With narrower gear there in the high and hard, skiers would have more fun. That the narrower gear can be made so very light is just a bonus.
The flip side. Or so it would seem. It is logical to conclude that firm snow performance and powder performance are at odds. In some ways, this is true. But it isn't a perfect, mathematical "zero sum" game. In truly excellent powder snow, narrow skis are a darn blast to ride. Good snow is good skiing, regardless of your equipment. Our time in deep Teton powder snow, on the Wayback 80 has been surprisingly enjoyable.
Narrow skis, in a connection that is no coincidence, make short, wiggly powder turns more like you'd see in a 1980s Warren Miller movie than in a more current offering. Ski design does influence ski performance. But very little adversely affects powder skiing. Anytime you change gear, you need to make an adjustment. You'll have to adjust to the powder performance of the Wayback 80, but you'll enjoy it nonetheless.
It is in tougher snow conditions that the Wayback 80 suffers. The narrow design and feather weight gets pushed around by uneven, variable, and chunky snow. Deep "mashed potatoes", breakable crust, and tracked up conditions are going to be tougher with the WayBack than with bigger skis. You can't get around this. You'll revert to survival type turns when the snow gets tough.
As compared to bigger skis, the Wayback 80 suffers in tough snow. As compared to other skis of similar weight and dimension, it excels. It is the poor snow performance that really sets the WayBack apart. We've used and tested multiple models in this size and weight range. In our testing, the WayBack 80 does the best. We do most of our early and mid-season BC ski gear testing in Wyoming's Tetons. January of 2020 was legendary, setting records for snow amounts. The quality of that snow was unparalleled as well. Testing for breakable crust took some creativity. We took the WayBack 80 out one early morning, after a sunny afternoon and just before then next round of new snow. We skied a couple of thousand feet of textbook breakable crust and had an excellent time. As compared to the closest competitors, the WayBack 80 definitely skis poor snow better.
These are expensive, fragile, specialized tools. You don't choose them for their value.
When they're the right tool for the job, we highly recommend the K2 WayBack 80. Its downhill performance transcends its ridiculously low uphill weight. Others making skis in this size range take notice; this model is new for 2020 and raises the bar.
