About Outdoor:
Outdoor refers to apparel, accessories, or footwear suitable for use in recreational or athletic activities in open air, outdoor environments. Since outdoor activities such as trail running, climbing, or hiking are often performed on uneven, rough terrain or slippery surfaces, outdoor shoes tend to offer better performance through an array of specific features designed to provide extra support, stability, and traction. Other types of outdoor activities such as camping, fishing, canoeing, backpacking, or kayaking may also require specific types of apparel and accessories.
JanSport Odyssey II Capacious
January 01, 2013
Reviewer: CA from Seattle
My middle schooler's backpack was too small for the laptop, textbooks, gym clothes, sneakers, and lunch tiffin he totes to school and back every day, so that's one was retired, replaced by the Odyssey. This fits it all, and has sundry pockets for the bus pass, calculator, pens and pencils, cell phone, etc. It's a monster (it's bigger than he is) but it does the job. His big brother has a similar Jansport (Airflight?) for 3 years, and it's uncomplainingly put up with plenty of abuse. Jansport seems to know how to make 'em.
