The Shift pro is the most comfortable harness in the range, suitable for people with a natural to flat lower back shape. The thicker, larger and less curved inner plate spreads the load widely over your whole back. This combined with the tender neoprene and EVA grip inside results in maximum comfort for everyday and powerful riding. The new neoprene padded spreaderbar with stabilizer wings locks the bar in place and eliminates the hook riding up and protects your ribs.
