Peak Designs 30L backpack – awesome!

Spent a lot of time on this site and others looking for a versatile and non box type backpack and the 30L version of this was the winner. Use it to commute via train in and out of NYC everyday. The modular interior had been very useful, allowing me to change it when flying, or between seasons, and still keep organized. Use the side compartments for all my cables on one side and snacks on the other side. Super comfortable with the chest strap being as easy to use and stow as they said it would be. My wife ended up getting the smaller version in the other color and loves it as well. Worth it!
