20l hiking backpacks

20-litre hiking backpacks are ideal for hikers seeking a compact model that is lightweight and perfectly suited for day trips and outdoor activities requiring minimal gear. With their smaller capacity, they allow you to carry all the essentials without being bulky, making them a preferred choice for nature enthusiasts and demanding athletes. For longer hikes or those involving overnight stays, it would be better to opt for a 30-litre backpack or a 40-litre model, also available at Glisshop.
