Mines just my general bag, it's not skate specific. I commute on my board most days so I keep a skate tool, a little speed cream bottle, good absorbent towels, some spare hardware and a bushing swap in the change pocket and then in the laptop pocket I have a gallon Ziploc with stickers, some grip scraps, a set of bearings, a chunk of wax, extra insoles, and maybe a set of wheels if I'm going to be skating something specific. Main pocket is usually just work stuff.
