The idea of a "shant" (short pant) is great but Dakine needs to tweak these...
I've been eyeing up Burton's shant pant for a few seasons but since I dont support Burton, I've been waiting for someone else to release one.
The purpose of the "shant" is to be shorter so it is not inside of your boot getting bunched up and potentially causing pressure points to your foot. The pant leg should end right above the boot.
When you put these on, they do end in the proper place. The problem however is that once you bend your knees (riding, jumping, etc) the pant leg instantly rides up to your knee. What happens then is you get a "gap" of uncovered leg (all socks start to inch down as you ride) resulting in a VERY annoying/distracting feeling. The problem is also compounded by the fact that the bottom does not have any sort of elastic cuff to hold its position. It is just a folded over hem which allows the leg opening to easily ride up to your knee.
IMO, Dakine needs to add a few more inches in length, allowing you to pull the bottom of the pant leg above your boot but also allowing room for knee articulation.
I've had some futile success by putting my socks over the pant legs to hold them in place but it only works 50% of the time. After 10 annoying days in these, I'm switching back to my full length base layer.
