The OnePack 50L is study enough to hold all my gear for a week in the wilderness but also to take all the stuff I would need for a girls week in Vegas. I was really impressed at how nice it look and how light the actual pack was. It is a backpack for anyone who wants to travel the world unencumbered by heavy, slow-moving wheeled luggage. The OnePack 50L has more than enough room for all the possessions you will need to travel the world. Clothes, a camera, a laptop, shoes and gear to go on pretty much any warm adventure you could ever want will fit in this pack. If you want to carry heavy jackets, going-out clothes, multiple pairs of footwear, or other bulky gear, you may want something a tad bigger. If you plan to pack through Europe or Asia for a few weeks or months this pack will hold everything you would need. It is small and light enough to take on any public transportation, or be able to explore a city without having to find a place to stow their luggage. It is not for business travelers who want to maintain appearances, nor is it for outdoor enthusiasts looking to spend six weeks on the Appalachian Trail.
