Outdoor Vitals CS40 Ultra Backpack

The Outdoor Vitals CS40 Ultra is an ultralight backpack with 53 litres of total capacity (41 L main body plus 12 L in external pockets) at just 765 g — a volume-to-weight ratio that puts it among the lightest packs in its class. The removable carbon fiber frame handles load transfer, a padded hipbelt with pockets moves weight to the hips, and back length is adjustable. The fabric is Challenge UltraWeave 200, a blend of high-tenacity polyester and UHMWPE fiber with a Challenge RUV finish — part of the dyneema/DCF laminate family known for tear resistance and water resistance. The main compartment closes via roll-top with no front zip access, and storage includes two stretch-mesh side pockets, trekking pole loops, and one ice axe loop, but no front shove-it pocket. The stated 16 kg max load capacity spells out its intended use: light gear for multi-day trekking and thru-hiking, not heavy loads. There's no built-in rain cover, so that's one more thing to carry separately.
