Outdoor Vitals SHADOWLIGHT 45L

The Outdoor Vitals Shadowlight 45L is an ultralight backpack with 45 litres of capacity (35 L in the main body) at 865 g, built around a removable aluminum stay frame. The hipbelt is padded, removable, and has its own pockets — anyone who prefers a minimalist build without a belt can pull it off entirely and shave off a bit more weight. The main fabric, 100D Robic nylon reinforced with 200D Spectra ripstop, steps up to a tougher 210D/400D version on the bottom panel where abrasion is heaviest, and overall water resistance is rated highly water-resistant. The pack opens via roll-top or a front panel J-zip, with two front and two side stretch-mesh pockets, trekking pole loops, and a key clip. With a 16 kg max load capacity and a weight-to-volume ratio of 19.2 g/L, it's geared toward light, fast multi-day trekking and thru-hiking rather than heavy loads — Outdoor Vitals rates it for extended trips of six-plus nights, provided your overall kit stays within ultralight territory.
