Why do so many wide skis suffer from delamination?

I'm not sure what you mean by "...so many wide skis..." or "...delam-a lot"

Could you be more specific, like models you feel are known to delam, or what you consider a delam, or a lot, or 'fat ski'??

I don't feel they do, what leads you to this question?

I would predict that disproportional number of skis returned on warranty are lamination problems on skis wider than 85mm. I've been reading reviews and also been considering which fat skis are well made, and the issue is common across several makes.

The reason for my response was, there is a delamination caused by a failure of the bonding process...and the 'delam' caused by tearing into the top sheet of one ski with the other ski.

One is caused by a manufacturing defect and one is caused by sloppy skiing.

I have two responses...

One is that the average fat skis get pushed harder than the average carving ski. They are skied in difficult terrain and see marginal snow. They get abused. They get slaped around in terrain parks, they get their tails jammed into the snow while hiking, thet get dropped off cliffs...

The other is fat skis are often built using a laminate lay-up and have seperate sidewalls. This choice of construction gives a smooth ride and can provide excellent edge grip but also tends to be fragile. Prone to delamination and sidewall failure.


At this level, durability often gets sacrificed for performance.

The main reason for more delams on a wider ski would be from inadequate press pressure to ensure that the glass is properly and evenly wet with resin. Too much resin "pooling" or too little resin "dry" will both lead to delams.

People are hucking cliffs on those skis, they are landing switch, they are riding them hard. I've also seen a lot of fatties with vertical sidewalls but nobody has shaped the top sheet. One edge nicks the sheet and because the nobody took care of the ski when they bought it now the have the top sheet pulling.
