The Gossamer Gear Mariposa 60 is the ultimate ultralight backpack for thru-hikers and weekend adventurers tackling big trips and serious mileage. Weighing just 34 oz (medium size), this 60-liter pack combines featherlight design with robust functionality, making it a favorite among ultralight enthusiasts. Crafted from durable, eco-friendly 100D and 210D recycled Robic nylon, it resists cuts and tears while keeping sustainability in focus.

Designed for comfort, the Mariposa features an innovative PVT Frame+Belt system with a closed-shape aluminum frame and pivoting hipbelt that moves with your natural gait, ensuring maximum comfort on long trails. The S-curved shoulder straps and redesigned load lifters provide even weight distribution, comfortably handling loads up to 30 lbs. Its removable SitLight foam back panel doubles as a camp seat, adding versatility without extra weight.

Organization is a breeze with thoughtfully designed pockets: a spacious front stretch-mesh pocket for wet gear, a deep left-side pocket for tents or trekking poles, two right-side pockets for water bottles and accessories, a top map pocket, and two large hipbelt pockets for snacks or electronics. The 36L main compartment easily fits bear canisters (like the BV500 vertically or BV475 horizontally), while the 24L external storage keeps essentials accessible.

Though not waterproof, the Robic nylon sheds light rain, and drainage holes in the side pockets prevent water pooling. For wet conditions, pair it with a pack liner. With its durable construction, customizable fit, and unmatched organization, the Mariposa 60 is your go-to pack for multi-day adventures, from the CDT to local trails.
