In some reviews and circles, these are light skis. Among human-powered skiers, though, a pair of skis at eight pounds is now the upper frontier of what is reasonable to cart around. The Black Crows Corvus Freebird is indeed a powerful and versatile downhill rider, but you pay the penalty on the way up. If you can stomach the weight trade-off, you will be pleased in all but the iciest of conditions with the Corvus. In tough snow, fast powder carving, and high-speed corn, the mass, and dimensions of the Corvus are unmatched. The Corvus is quite a bit lighter than comparable resort skis, which might make them appealing as your first backcountry skis. We can report, though, on good authority, that most are better served with skis for human-powered use that are even lighter than the Corvus Freebird.We can recommend these skis for two very select user groups. First, these are great for the super-strong climber that absolutely has to have optimum downhill performance, for whatever reason. Next, and we make this recommendation very reluctantly, we suggest these skis to those that insist on having a "quiver of one" that will work at resorts and in the backcountry. Resort skiing and backcountry skiing have very different demands, and asking one set of equipment to do both is a tall order. Many, many users seek equipment for these dual purposes, and there are almost as many users who are disappointed with the performance of their chosen product in either or both settings. It is a difficult compromise to swallow. Of course, you may not know the difference. If, though, you have any exposure to human-powered touring on actual lightweight gear, you will have a tough time stomaching the energy expenditure associated with a bigger kit.

Our Analysis and Test Results
Big guns! Among "touring skis", despite what manufacturers' branding might suggest, these are as heavy as you should be considering. The Black Crows Corvus Freebird is almost twice the weight of our lightest tested skis and is more than twice the weight of skis our testers use on specialized missions. Other "backcountry" ski reviews mention just how light the Corvus Freebird is, but then go on to compare it to resort alpine skis and to refer to testing performed inbounds. The Corvus Freebird is light, as compared to resort skis. Here, we're comparing them to skis for human-powered riding. That is how Black Crows pitches them.
In actuality, as compared to all that is available, these are super heavy touring skis or light resort skis. Sure, there is a place on the market (and maybe in your possession) for skis that bridge the gap between resort and backcountry, but they will be ill-suited for either application. This is a typical compromise piece of equipment, sitting on the fence separating different worlds. Read on for the summary of our largely favorable (once we adjusted to and allowed for the additional weight) experiences. Our experiences were favorable enough that we granted the Corvus Freebird our Top Pick award.
Eight pounds for a pair of backcountry skis is heavy. When there are choices on the market that are under five pounds, it is difficult to justify lugging these up giant mountains with your hard-earned calories and muscles. The only justification is downhill performance. And lighter skis keep performing better and better.
All the other skis we tested are at least a little lighter than the Corvus Freebird. Earlier in our ski testing, years ago now, we reviewed a few skis even heavier than these. Eight-pound skis five years ago were close to average, for human-powered skiing. But technology just keeps improving, and skis get lighter while maintaining reasonable performance. Of course, as we note extensively in our main comparative article, in our Backcountry Ski Buying Advice, and in each product review, weight does enhance downhill performance, up to a point. All else equal, heavier skis are going to go downhill better than lighter skis. That means that this Top Pick Corvus Freebird is the best downhill performer in our test.
On the surface, according to our chart, the Top Pick Black Diamond Glidelite Snow Trekkers appear to weigh a little more than the Corvus. This is misleading. The Snow Trekkers are a specialized piece of equipment for casual exploration, and they include bindings and permanent skins that none of our other skis include.
When we eliminate weight from consideration, the Freebird is the highest scoring in our review. It is notable, though, that some approach the overall downhill performance of the Freebird and weigh more than a pound and a half less for the pair.
Stability at Speed
Of the major performance attributes, stability at speed is most inverse to weight. Mass literally helps stabilize your speed. Of course, other attributes enhance stability, but weight is right in the mix. As heavy skis (and skis that are very well made, with excellent dimensions and careful attention to materials and assembly), the Corvus Freebird are very stable at speed. These skis prefer high-speed riding, and track through tough stuff and smooth conditions almost equally as well. Of course, resort skis are going to be more stable, but for touring-specific sticks, the Black Crows are very stable. On wide-open Teton powder and big Sierra corn faces alike, the mass and long turning radius of the Corvus Freebird will inspire confidence underfoot. Size them long to get the full benefit of their stability.
No skis we tested compare to the stability of the Corvus, especially when we compare across varied snow conditions. Some come close in certain conditions, but the Corvus Freebird is tuned for all the snow types.
At high speeds, firm snow performance is more of a stability performance issue. For that, see above. The Corvus Freebird's stability advantages transfer just fine to fast and firm. That mass and the torsional rigidity (likely attributed to the sandwich construction and thick wood core) of the Corvus Freebird make for good hard snow carving capability. At lower speeds, usually on steeper and higher consequence terrain, the criteria for hard snow performance change a little bit. Stability is less important then than absolute edge hold and relative tip-to-tail edge hold. Wide skis require more force to grab hard snow. The Corvus Freebird is among the wider skis we tested for 2019-20 and struggles to hold on the hard steeps as well as narrower skis. The good news is that the tip-to-tail edge grip distribution is perfectly balanced. Tip nor tail seems to grab unnecessarily, and the forces are distributed evenly underfoot.
We pretty deeply discount hard and fast low angle backcountry ski performance. These conditions and terrain set up just aren't that common in the wild. Carving at high speeds on rock hard snow is more of a resort ski consideration. Nonetheless, these skis do pretty well in that context, especially considering their width. Of course, resort carving skis will beat the pants off the Corvus Freebird, but the torsional rigidity and mass do a good job of exceeding the performance of most of the backcountry skis we have assessed.
We look more closely at steep and firm ski performance in this review. This is actually a very common backcountry skiing situation, and one that is high consequence; you need your backcountry skis to grab predictably and reliably in slow, technical, steep, icy skiing. In these contexts, the weight and width of the Corvus Freebird could be an issue. When one is conditioned to methodical steep skiing, lighter skis come around easier, to a point, of course.
The sweet spot for weight for steep and hard skiing is something below the weight of the Corvus Freebird, our test team has found. The same can be said for ski width. Steep and firm riding rewards a sweet spot of width, usually around 80-90mm. At 109mm, the Corvus Freebird takes a lot of leverage to grab on ice. If we were choosing skis for just steep icy snow, we'd go with stiff, light skis around 90mm underfoot.
In so many ways, powder skiing is what we live for. Even a dedicated backcountry skier might spend an entire season chasing a few thousand vertical feet, on one or two days, of perfect deep powder skiing. Because it is so fun, we highly prioritize powder skiing performance. It isn't that common, though, and there is a vast range of skis and ski design considerations that make for excellent powder performance. High powder performance is relatively easy to achieve, technique-wise, and in terms of equipment. All modern skis of "normal" dimensions ski powder very very well. That being said, there are subtle differences. The Corvus Freebird is very floaty in powder and likes to go real fast in the softest of conditions. It is more difficult to slow things down and ride shorter radius turns.
The best powder skis we test float high in high speed turns and pop in all three dimensions in slower, shorter-radius turns. The Corvus Freebird excels in the former but require more work in the latter. The most versatile powder skis in our review bring a secret sauce of performance attributes that both wiggle and slay. The dedicated powder boards, though, don't handle non-powder skiing as well as the Top Pick Corvus Freebird.
Like with stability, poor snow performance is enhanced by mass. Heavier skis bust through the crud better; also, wide skis are less likely to get grabbed, deflected, or thrown around by tough snow conditions. The Corvus Freebird, for these reasons, are very high scoring poor snow performers. In breakable crust, after correcting for differences in individual's technique, the Corvus pushes further into the spectrum of poor snow before requiring reversion to survival skiing tactics. The same can be said of sloppy "mashed potatoes" type snow, though our team found that in the most difficult of wet snow, the length, weight, and width of the Corvus is overwhelmed in low-speed survival slop snow turns. When you have to slow things down, smaller and lighter skis (to a point) are easier to maneuver.
No skis, overall, ride tough stuff as well as the Corvus Freebird. Weight and width are on the side of the Corvus. Smaller skis, even those that aren't that much smaller or lighter, get pushed around.
The Corvus Freebird construction helps the size and mass of the ski to do its job. The round and gentle longitudinal flex pops up out of the tough stuff, while rocker geometry helps further.
These are expensive skis for a narrow niche of users. If you fit that niche, though, the Corvus Freebird should be high on your short list.
For the discerning downhill skier with energy to spare on the uphill, these big guns are worth considering. If you are looking for skis to use both inbounds and out, first see above for our warning on this strategy and then consider the Top Pick Black Crows Corvus Freebird. In total, these are just too heavy to score near the top of the heap. No amount of downhill performance will overcome those additional pounds for the average human-powered skier. For the occasionally human-powered skier, especially one that prefers absolute downhill performance, the Corvus Freebird might be just the ticket.
