I only used this bag once on a short leisure trip, but I don't need all of the features it provides -- specifically the laptop compartment. This bag has great features though and even fully packed it fit under my seat and easily in the overhead compartment on the plane. It meets all TSA and airline carryon size requirements. Features: - Expandable main compartment from 22L to 40L - Fits everything necessary for 3-5 days - 17" Padded laptop/tablet compartment - Luggage strap - Built-in USB port and charging cable in front pocket - Waterproof outer material - Main compartment features a waterproof zippered compartment - Heavy-duty zippers and reinforced stitching - Side zippered pocket for water bottle - 3 slim front pockets for small items (phone, ebook reader, tickets, etc.) - Padded side and top handle - Padded, adjustable backpack straps with adjustable chest strap - Cushioned back with breathable mesh fabric For additional information and photos visit: https://www.amazon.com/dp/B0C38M5Z4K?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 Excellent condition. Smoke-free, pet-free home.
