When Seth Morrison stepped onto a pair of skis for the first time, the world of big-mountain skiing was irrevocably changed for the better. Instead of hopping his way down a face, Seth made arcing, powerful turns at speeds that would melt the face off a merely mortal skier. The K2 Annex 118 Seth Morrison Ski is Seth's latest pro model ski—it's designed to support this hard-charging, high-speed style of skiing for him, and anyone else wishing to come along for the ride.

A triaxial braid of fiberglass is wrapped around a fir, aspen, and maple wood core in the heart of this ski. The result is a lively flex and the sort of torsional rigidity that begins to close in on the performance and precision of a carving ski, albeit in a package that is anything but. The Hybritech sidewall gives you the lightweight response of a cap ski with the performance and durability of a full sidewall so you don't have to compromise anywhere on the mountain.

The powder rocker features more taper in the tip and tail than previous iterations, allowing for graceful, nearly effortless turns down huge faces, as well as versatility in nearly any conditions. The low-rise tail lets you plunge this ski for use as a temporary anchor, should you find yourself in need. Speaking of getting out and after it, the tip and tail skin-attachment grommets let you attach any of K2's custom skins with ease, meaning you can get more time skiing, and less time fiddling with your gear.

Unanswered Question

I'll be at Alta next year and would like to get these as a touring ski (I'd mount them with a pair of barons I have), but am just a bit concerned about the weight. 2500 g is more than almost any other ski, and although I'm not someone who tries to tour super light or does long overnight trips really, I'm wondering whether I should look to a different wide ski for the touring set up because the annex's are on the heavy side

  • Familiarity:I've used it once or twice and have initial impressions

Had the chance to ride a few days on these as a demo at Mount Bachelor. Coming from my 192 Blizzard Cochise the 177 Annex was playful yet still had the power I was used to from the Cochise. Going through a mix of windblown powder and concrete hard pack, these guys held up like champs to a varied mix of snow features.

I wear a size 29.0 boot and want to mount the Salomon Guardians MNC 16 on this ski. Would the L 115mm work? Or would I need the L 130mm?

Best Answer

Alex , go with the 115mm Brake , it can be bent slightly to fit the Annex 118.

Hey Alex,

Soren is right - that 115mm can bend enough to fit that 118mm waist.

Since you mentioned boot size... You can check the sole length on your boot but I'm sure any size 29 boot would need the Large Guardian. Small only accommodates up to 320mm sole length. The Large will work with an AT or alpine sole length range of 305-360mm! Large 115mm should be perfect for this ski.

Does anyone know what the weight per ski...

Does anyone know what the weight per ski or combined is on the 191cm Annex 118? Can't seem to find it published anywhere. Thanks.

K2 has not yet compiled those specs for this new model and I do not have the resources to accurately weigh a ski but I did talk to a K2 rep that estimated the length at 2500 grams each.


Some Improvements

  • Familiarity:I've put it through the wringer

Taper in the tip and all black bases are the biggest changes form last year. I find the taper helps float the ski quicker and allows for easier steering in soft snow. Not to much die cut, just logos so the skis will be faster than most. Seeing that many people spray painted their set ups, all black top sheets with some minimal graphics. Still a daily driver, not alot of tail rocker so the hardpack is as effortless as riding them in powder. Tip and tail holes work with k2 skins and Rescue Shovel Plus, with parts in the handle of the shovel you can build a rescue sled along with some cording.

where do you mount your bindings? +1 etc...........

How about hard snow conditions compare with Sideseth?
