FWIW I have SL-100x purchased in January and ST-120x purchased in May, both tag 36. The pockets measure the exact same distance from the top of the waistband to the top of the pocket. The ST pockets measure about 1/4" longer and the same width, so they are a tiny bit larger. Basically unnoticeable difference between the two.
Thanks for bringing this up. The current SL and ST fits are finalized and will not be changed going forward. For those who might want the pockets to sit higher, you might want to consider our CS-100x cut that will be coming out later this summer. This is the straighter leg, higher rise jean that sazon mentioned; CS is named for "Classic Straight" as it's a more vintage inspired fit.
