Mountain Hardwear Women's Lamina™ 15F/-9C

The Mountain Hardwear Women's Lamina 15F/-9C is a women's-specific mummy bag built around Temperlite synthetic insulation and Mountain Hardwear's welded Lamina construction, which bonds shell to liner without sewn-through seams to avoid cold spots. EN ISO 23537 testing rates it at -9°C comfort, -16°C limit, and -36°C extreme, placing it in the 3-4 season range for cold trips rather than mild three-season camping. At 1715 g with 1393 g of fill, it's noticeably heavier than a down bag rated to the same temperature — the usual trade-off for synthetic insulation, which keeps working when damp and skips the careful drying down demands. The 20D polyester ripstop shell has a DWR finish, the hood is adjustable and contoured, a draft collar seals warmth at the shoulders, and it packs to 46 x 24 cm with a stuff sack and storage sack included. Sizing fits users up to 173 cm. It fits hikers who camp in cold, damp conditions where reliability matters more than shaving grams — shoulder-season trips or a dependable backup bag rather than an ultralight thru-hike choice.
