Thank you for viewing. This is the deuter Aircontact Lite 40+10. It's a size suitable for both overnight camping and day trips. I bought it for tent camping. It's a well-made and reliable backpack. The back padding reduces sweatiness when carrying it, making it comfortable even in the summer mountains. I used it for one night of tent camping, and it has sufficient capacity. The top can expand to increase capacity, so it can handle extra luggage. The compartments can be divided, allowing quick access to packed items. I purchased it in 2023 and used it about 5 times for tent camping. I'm selling it because I don't plan to use it anymore. There are some scratches from use. Please check the photos. Please note that I cannot negotiate the price. - Brand: deuter - Material: Backpack panel with mesh padding - Features: Adjustable straps - Color: Gray - Size: 40L+10
