Deuter Weybridge 25+5

"The Weybridge 25+5 bike bag from Deuter is the ideal companion for anyone who likes to travel by bike, whether mountain biking, cycling or road cycling. With a basic volume of 25 liters, which can be expanded by a further 5 liters thanks to the practical 2-Wege-Roll-Top fastener, it offers enough space for all your utensils. The bag is waterproof to IPX4 standard and reliably protects your luggage from rain and splashing water."
"A special highlight of the bag is the innovative BagFix mount, which ensures that the load is 100% on the rear wheel and not on your back. This ensures maximum freedom of movement and comfort while riding. The adjustable carrying handleclosure and detachable shoulder strap allow the bike bag to be quickly converted into a practical shoulder bag that can also be carried comfortably off the bikeu00e4sst."
"For additional safety in the dark or in poor visibility conditions, reflectors are integrated to ensure better visibility in road traffic. Inside the bag there is a compartment for securely storing valuables and an organizational unit to keep things tidy. The edge protection on the bottom of the bag protects the bag from damage and increases its durability."
