R&R Bloodline Flannel Shirt

FlexTec™ is the technical movement system from Rockers & Riders.
Not just a buzzword, but a precisely developed construction principle – directly from practice, based on real riding postures, grip movements, and carrying requirements on the bike.
FlexTec™ Shoulder Panel
Used in our shirts.
The shoulder panel consists of elastically mounted fabric segments with internal stretch zones that stretch in a controlled manner when reaching forward (e.g., to the handlebars).
This keeps the shirt in shape even in a forward-leaning sitting position, prevents it from riding up, doesn't pull under the armpits, and always sits securely on the body.
When you bring your arms back, the system contracts again – without wrinkles, without bulges. The result: technical mobility without optical compromises.

FlexTec™ Side Panel
Used in our vests.
The side extensions consist of a robust, water and windproof zipper with an elastic base – flatly integrated, almost invisible when closed.
When you open them, you gain 4 centimeters of circumference on each side – ideal if you wear several layers or a thick jacket under the vest in colder seasons.
Closed, the system completely disappears into the design – without affecting the look, but with full functionality when you need it. FlexTec™ doesn't put on a show.
