Thule Vital 3L

"The Thule Vital 3L backpack is the ideal companion for anyone who doesn't want to compromise on comfort and functionality even on fast bike tours. With the innovative ReTrakt tube retrieval system, you can drink without having to take your backpack off, which ensures a smooth and uninterrupted flow. The optimally designed pockets allow quick access to provisions, clothing or tools, so that you are also well equipped during the ride."
"Thanks to the well thought-out weight distribution and a low center of gravity, the Thule Vital 3L improves handling and reduces muscle strain, which is particularly beneficial on longer distances. The Hydrapak hydration bladder with a capacity of 1.75 liters ensures that you always stay sufficiently hydrated, while the 3-liter storage compartment offers enough space for additional provisions, clothing and tools."
"The backpack is made of lightweight and breathable materials that guarantee maximum performance both uphill and downhill. Your personal items such as phone and keys are safely stowed in the inner zip pocket. The backpack also has an attachment option for a rear light so that you remain clearly visible even in poor lighting conditions. The integrated chest strap provides additional stability and comfort in any terrain."
