Daypacks, laptop backpacks, hip packs and duffels — largely Dakine, with Thule, Mountainsmith, Poler and DC alongside.
On volume: 20–30L covers a day of class or a day on the hill, 30–40L handles an overnight or a carry-on, and duffels take over above that. Some unisex packs are only filed under Packs & Bags, so it's worth checking there too.
