The Hesper 50 is a lightweight single-compartment pack series designed for versatile use, from day hikes to long-term backpacking. Weighing only 1,190g (size S2), this technical pack boasts a capacity of 52L, capable of holding all your necessary gear. It features a lightweight back ventilation panel called 'Helium Air' and incorporates a lightweight frame tailored to the body's contours for improved fit, even in scenarios where load balance is easily disrupted. The main compartment offers a simple roll-top design with a single chamber and includes compression straps that adjust based on your load. The removable rain cover adds convenience, while the front and side stretch stash pockets facilitate quick access to your gear. The shoulder harness includes a pocket for a soft flask, and the waist harness is detachable. Macpac products W1 and W2 are women's sizes, while S1 (size 1), S2 (size 2), and S3 (size 3) are unisex harness sizes.
