With the Aeron Lab Ultralight 2.0 cycling jacket from dhb you get lightness, a small pack size and protection. It's completely waterproof, yet small enough to stow in your back pocket: why leave home without it? Weighing in at 110 g (men's size M), this jacket is possibly the lightest as a feather yet the most protective on the road. Using a 3-layer fabric, dhb has not compromised on weather protection while maintaining a weight and stowability you won't notice all day. Until you need them of course!
