Capacity – The capacity of a daypack is measured by the amount of liters it will carry. Generally, you want around 20L-30L for a standard daypack. We recommend 20L+ so you can carry all the gear you want.
Back ventilation – Some daypacks have mesh back panel that allows for more airflow and ventilation. If you tend to get a sweaty pack, we suggest a mesh back panel daypack. Also, we find that many hikers find mesh backed packs to be more comfortable overall.
Hip Belt – A hip belt distributes the weight of your pack to your hips and off your shoulders. Also, most hip belts have convenient pockets so you can access your phone, sunscreen, or other other items quickly. For longer camping hikes, we like to have daypacks with hip belts.
