Mountain Hardwear Lamina Eco AF™ 30F/-1C

The Mountain Hardwear Lamina Eco AF 30F/-1C is a lighter-weight sibling in the welded-baffle Lamina range, built for 3-season use rather than the colder-rated Eco AF models. Unlike most synthetic bags that rely on manufacturer estimates, this one carries an EN ISO 23537 lab rating: comfort 3°C, lower limit -1°C, giving a more directly comparable number against other tested bags. The 540 g Thermal.Q Recycled fill sits inside a shell and liner made entirely from undyed 20D recycled nylon ripstop with a PFC-free DWR coating, continuing the Eco AF line's focus on minimizing dye and water use in production. At 870 g total weight and a 218 cm internal length with 147 cm shoulder and 132 cm hip width, it packs down to 7.9 L – reasonably compact for a synthetic bag, though still bulkier than an equivalent-warmth down option. A full-length two-way zipper, draft collar, and included stuff and storage sacks round out a bag suited to shoulder-season backpacking where synthetic fill's wet-weather reliability outweighs the weight penalty versus down.
