Have we eventually designed the perfect Ultra racing pack? We are always looking to improve, but here we are reaching perfection according to feedback from athletes. The Responsiv 12 has been an ongoing development for years, firstly 8, then 10, now 12. each time evolving to an improved version. Now this race vest is lighter, more comfortable, more versatile than any of the previous models.

Useable from 2 to 12 litres this race vest has amazing versatility. 4 compression cords on the rear stabilise the load or give an additional pole storage option, the front stash pocket can take handfuls of your chosen energy and you can carry as much hydration as you should reasonably need.

The monofilament mesh harness distributes load evenly for comfort without any thick padding that absorbs moisture and adds weight. The adjustable position elasticated chest straps and FreeLock micrometric dials give the ability to perfectly tailor fit and stop the dreaded bounce.
