BIRKAN running T-shirt Black

This T-shirt is new for running.
It has a waterproof zip on each side.
The goal?

• Open zips for maximum breathability in hot weather.
• Feel more comfortable: if the bottom of the T-shirt compresses your hips, simply open the zip.
  This product is recommended for running without a Trail bag, as our experts believe that the zips on the sides are not compatible with wearing a bag (this can create friction).
  The material is eco-recycled from plastic bottles.
  This product features Rudolf Silver-Plus® treatment for anti-bacterial and anti-odour protection for up to 20 washes.
  The prints are sublimated for optimum durability.
