All Terrain Rocker
ROCKER: Easy initiation, versatility, agility
CAMBER: Control, edge hold, rebound
All-Terrain Rocker features an elevated tip for variable and soft snow performance, as well as camber underfoot for power, energy, and edge-hold in firmer conditions.
Simply put, All-Terrain Rocker offers versatility and ease in all snow conditions.
-
Powder-Specific Tip Design
The widest point of a powder tip is 7cm back from the standard contact point. The design adds stability and predictability while skiing and is less likely to hook or grab in light crusts or variable conditions. -
Progressive Sidecut
Progressive sidecut is a combination of two different radii, or sidecuts, that enhance the versatility of wider-waist skis. Standard sidecut theory is based on using a single radius. This works well on narrower skis, but becomes overpowering on wider skis, especially in variable conditions. The use of progressive sidecut on wider-waist skis guarantees improved turn initiation and hard-snow performance. -
BIO Core Tech
For backcountry skiers conscious of their caloric and environmental output, our Adventure skis use a blended core of aspen, bamboo, and Paulownia, (a reforestation plantation tree similar to bamboo) that has consistent density, great strength-to-weight ratio, and fast-growth carbon-sequestration. The core is just one component of the ski, but the result is 15% weight savings over our traditional fir/aspen cores and a lessened footprint, reducing the impact of the ski on you and the winter world. -
Tip and Tail Holes
Holes in the tip and tail are not only the attachments points for K2 skins, but they also fit the functional needs of a backcountry skier including the ability to build a rescue sled or construct various ski anchors. The holes are equipped with removable plugs. -
Flat Tails
All Adventure skis come with flat tails, providing backcountry utility by allowing you to plunge the tails easily into firm snow. -
Skin Clip Arc
The tails of our Adventure skis are designed with a concave notch to ensure that the skin clip, regardless of size or skin brand, stays securely centered on the tail. -
Hybritech Construction
This wider-waisted construction combines the accuracy and power performance of sidewall underfoot with the lightweight and smooth turn initiation of cap construction. -
TNC Construction
Weight reduction is paramount in the BackSide model line. We've tooled a BackSide specific TNC Metal Laminate Construction that lessens weight wile providing an accurate and responsive feel.

Comments about K2 Skis HardSide:
These skis flat out rip and will go anywhere. Float in deep powder and absolutely bust the crud like no other ski I've been on. Amazing in the moguls and will carve on the groomers except in the iciest conditions. Those who say this ski doesn't float well on powder should consider taking a lesson! This ski is a true one quiver ski if that's what you're looking for.

Comments about K2 Skis HardSide:
I have been skiing 20 years. I am demo testing skis this year to figure out what to buy. Stevens Ski Resort in WA suggest this ski to me. It is the widest ski I've been on. I just fell in love with it. Am looking now to buy a set.

Comments about K2 Skis HardSide:
I demoed these skis (181 mm) this past weekend at Breckenridge. These were such a fun ski in all conditions. I am 5'10 200lbs and ski very aggressively. They handled really well on the groomers and were a blast in the crud. I demoed the Nordica Hell and Back a few weeks ago at Breckenridge when they got 10 inches of new snow but feel the Hardside is a better ski in the crud and powder. At speed the Hardside was much stiffer than the Nordica and I felt much more confident skiing the Hardside in the crud and groomers. Overall, an excellent ski!

Comments about K2 Skis HardSide:
After one week of skiing around the Chamonix I have tested Harside on everything from blue ice to 1 m deep powder and these are my thoughts:
HardSide is too slim and too stiff to be a powder ski, too heavy to be a tour ski, too soft to be a piste ski. However, it does a bit of all worlds, and it does quite ok, but do not think this is the magical answer to all snow conditions.
I loved these skis in the hard crud and the crust, but they were dwarfed by some other real powder skis I tried on the same trip. If I were to re-make my choice, I would go for the SideStash to favour the soft-snow conditions and pay the penalty of few hundred grams per ski. And then keep a real tour ski for the next trip on Haute Route.

Comments about K2 Skis HardSide:
I live and ski mostly in Scotland with yearly trips to the alps and very occasionally the US/Canada. When I was looking for a new ski, I needed a ski that could be as good at everything it could be without focussing directly on any one discipline. Scottish conditions can vary wildly from powder one day to horrid slush the next (or same) day and mostly everything between. The hardside has excelled in everything I've thrown at it. Coming from the Xplorer I was immediately at home on these as they had very similar characteristics, perhaps having even better edge grip. They coped very well with hard compact conditions on and off piste in the 3 Valleys last season (2011) and were not too bad in a steeps lesson that took the moguls on the telepherique line in Courchevel 1850. For a ski that can rail on the groomers and also bust crud and handle deeper softer snow and a bit of slush, I don't think I'd want anything else. The Hardsides have the advantage of a flat tail which makes them a much more versatile back country ski. A little heavy for an extended tour anywhere, but the most skinning/booting i'll be doing is under 1 hour so these are perfect.

Comments about K2 Skis HardSide:
I have used this ski in bounds crud and pow and heli skied around 300,000 vertical feet in many conditions in the past two years. These skis rock! You are in the snow vs. on the snow.

Comments about K2 Skis HardSide:
I had the same problem as PFFlyer. Wide ski, rocker tip and for some reason I am sinking in the pow. Maybe my 181's are too short to float my 200#'s but
this is not what I expected from these skis. They do perform well in all other soft snow conditions.

Comments about K2 Skis HardSide:
Tested a pair of these on a day when we'd just had 14 inches of fresh dry powder. Some things they do remarkably well. They were tremendous in the tracked up powder and crud, they blow right through it. Getting back to the lodge on the groomers they were well above average for an off piste ski. They also behaved very well in the moguls. The problem was with their performance in the beautiful, new, untracked powder. The tips sank like they had boat anchors attached to them. All the way to the bottom of the powder. Given the amount of rocker and their width this seemed inconceivable. Had to lean very uncomfortably on the tails when I came off steep powder since anytime the terrain flattened out I was almost thrown out of the front of the skis due to the deceleration from all the drag on the buried tips (along with my ski boots and shins). Even riding the tails I couldn't pry the tips back to the surface. Managed to get them to do what I needed throughout the day, but they made for the toughest day I've ever had with a foot of new powder. My old race skis handled powder better than these. Also don't recommend getting any air under them, the skis absorb noting on impact, instead they transfer it all directly into your legs and back.

Comments about K2 Skis HardSide:
As a hard charging 64 year old, male, ski anything skier, that has been skiing Volkl Mantras for years, I jumped on these and immediately knew I was jumping up a big step.
I ski about 100 days a year at mostly Squaw Valley and with our varying conditions on difficult terrain it is great to have one ski to do it all.
The Mantra was a great ski, but the Hardside, is like skiing the Mantra on Steroids, quicker,lighter, more stable on all conditions.
Skiing bumps is very easy, no harshness, and great edge hold.
Think turn it turns, crud, cuts like a knife, ice is just noise.
Love these skis
The graphics were a little too much, almost turned me off to the ski.

Comments about K2 Skis HardSide:
I've been on these skis since Dec '09. They flat out rip in mixed conditions like pow on bumps. They keep me up right if I mess up a landing 'cause only the deepest auger will stop 'em.
