Two of them, both gear based and both from the new review system.
^^This shows you my 'gear' - which is a list of my current gear that I'm rocking. You maintain it by looking at items in the review system and selecting 'add to my gear'. You have this too, though you may have not selected/reviewed your current gear.
^^This shows you a list of every review I've ever done. This is a way of seeing all the gear that someone has ever used, and what their opinion of it was.
The goal with all of this is to continue to build out both our gear database, but also allow you to get an idea of what kind of gear various people use. Its very helpful to know more about a skier that is using gear, vs. just their opinion of it.
With this in the profile you can check out videos, pictures, forum threads, stats, etc. at the same time as gear. So you theoretically (if someone contributes to NS) get a way better overall picture of them as a skier while reading their gear selections.
Anyway... all the gear stuff is still mega in beta so bear with the few bugs that are still in there, but its coming along faster by the second.
