Would this pack be one I could use both in the summer riding my bike but also skiing in the winter?
Yes. Not exactly loaded with specific winter pack options, but for carrying a small load and some water, perfectly appropriate for either activity and season.
hey there - great choice all year! And, on August 1st, Osprey is introducing their own insulated tube to make that pack truly all season. Have fun!
