I spent a long time searching for a 20L daypack that would work equally well for city and outdoor use, and this one ticks every box. Iโm 165cm and the S/M fits well.
The bag has everything I was looking for: a stowable hip belt, well-designed pockets (including a super handy phone pocket on the shoulder strap), and roll-up adjustable straps that keep everything neat and tidy. The side pockets easily fit my 1L Nalgene, and the stretchy kangaroo pouch comfortably holds layers, wet gear, or camp shoes when the main compartment is full. Toggles for hiking poles and a waterproof cover were must-haves, and both work as needed.
Iโve used this pack on several multi-day hikes where I didnโt need to carry much gear, and itโs been very comfortable for 8+ hour days.
