"The Patagonia Atom 20L Tote Pack is built for the day that starts at a desk and ends on a trail, or the trip where one bag has to cover the airport, the city, and the weekend hike. The top-loading tote opening keeps access fast, while the 400D postconsumer recycled polyester ripstop body holds up to the daily grind without adding weight to the carry. What Our Gearhead® Experts Are Saying:""Pull the laptop sleeve out when the bag is going hiking, drop it back in when the commute calls for it. That one swap is what makes this pack work for a mixed-use day."""
