This is my review of the Osprey Daylite Daypack, after a year of torturing traveling with it to over 10 countries. Since I’ve been using the reliable Sojourn 60L as my primary check-in luggage for years, I decided to try the Osprey Daylite, hoping it too would be worth the sightly higher price tag. The Daylite is 22 x 22 x 45 centimeters, holding roughly 13 liters in two main compartments. Dual side pockets for water bottles and the hydro-bladder on the back remind you Osprey designed the Daylite with hikers in mind.
