Extremely durable, generally anything made by the NeverSummer factory is gold.
Ninthward (couldn't say that a few years ago)
I know I'm forgetting a couple, but you get the picture.
I generally get about 140 days in on a pair before the edges start to blow out from rails. If you're not skiing rails though, bet you could get in a solid 3 or 4 years of use in on them. Pretty durable skis
Really solid skis. If you're 180+ pounds and doing lots of presses/butters, you will find that the get flexed out over the course of a full season (60+ days). But this is to be expected with any wood core ski.
Besides that, they are some of the most fun and playful skis on the planet (I work at a ski shop/at ski demo's, and have ridden most of the skis on the market). 10/10 would recommend almost anything in their line!
