The NEMO Disco 30 women's bag is the milder-season sibling to the Disco 15, sharing the Spoon shape and 185 cm women's-specific cut (max user height 167 cm) but carrying roughly half the down — 440 g versus 830 g — for a -1°C comfort and -7°C limit rating better suited to summer and mild 3-season nights than deep cold. The 650 fill-power hydrophobic duck down is US-standard rated and RDS-certified, and unlike some other Disco variants in the line, this one is noted as PFC-free.
Total weight is 1,050 g, roughly 350 g lighter than the 15° version, trading warmth margin for pack weight and bulk. It keeps the full-length, single-direction zipper on the right side, a draft collar to limit heat loss at the neck, and foot-box venting for warmer nights. A stuff sack and a separate breathable storage sack are included, which matters for maintaining down loft over repeated trips. It's a solid choice for women doing 3-season backpacking who don't need the 15° model's deeper cold margin.
