This pack is really comfortable and sized for a woman. I actually got it for hiking, skating, and cross country skiing but I will use it for biking as well. It's very adjustable over thick winter fleece or just a tee-shirt. It's well ventilated so it's comfy and insulation keeps the water cool too. It's easy to fill, and clean, with the wide mouth opening. I only wish the cargo pockets were a bit larger to fit a camera. It's a great choice for someone who wants to travel fast-n-light with a balanced load.
