Mountain Hardwear Lamina™ 15F/-9C

The Mountain Hardwear Lamina 15F/-9C is a men's-specific synthetic mummy bag rated by the manufacturer to -9°C, a 3-season option for spring, summer, and autumn trips rather than winter use. Like the rest of the Lamina range, it relies on a seamless welded baffle construction that spreads the Thermal.Q synthetic fill evenly and avoids the thin, cold-prone stitch lines of sewn-through bags. At 1393 g total weight, packing to 46 x 24 cm, it sits mid-pack among synthetic mummy bags – heavier than an ultralight down bag rated to the same temperature, lighter than the brand's dedicated winter and expedition Lamina models. The weight-per-degree figure of roughly 155 g fits mid-weight synthetic insulation rather than premium down, the usual trade-off for a bag that tolerates damp conditions better and costs less. The 30D nylon ripstop shell carries a DWR coating, and a fitted draft collar seals warmth at the neck. Regular sizing fits users up to 182 cm, with a men's-specific cut setting it apart from the brand's unisex models; zipper side and included accessories aren't specified.
