LC BY LOWERCASE
LC BY LOWERCASE / Daypack 01
This compact model is perfect for daily commuting to work or school, or for walking around town on holidays. 840 denier junior ballistic nylon is luxuriously used to provide abrasion resistance, puncture resistance, and tear resistance while being lightweight.
While maintaining the same simple look and feel, it inherits the storage capacity and smart design of the 30L model, offering a size that makes daily use easy along with sophisticated design and high practicality.
The 30L model is best suited for overnight trips and situations with a lot of luggage, whereas the 20L model is a backpack born for everyday use.

Durable Yet Refined: Junior Ballistic Nylon
