Raidlight says:

Flagship of the Responsiv range. The Responsiv 12L Race Vest is an ergonomic and lightweight trail running pack. You can pack your essentials for most runs and races in lightweight comfort. This race vest has been seen on the podiums of many classic 100-mile races around the world.

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, then 12 and now the V2 updated Responsiv 12. Each time evolving to an improved version. We have added accessible storage pockets and this V2 version is directly compatible with our Trail Quiver.

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 2 stretch stash and 1 zipped pocket on the front can take handfuls of your chosen energy and you can carry as much hydration as you should reasonably need. We have added an accessible zip rear pocket if you need more storage. The monofilament mesh harness distributes load evenly for comfort without any thick padding that absorbs moisture and adds weight. The elasticated chest straps and FreeLock micrometric dials give the ability to perfectly tailor fit and stop the dreaded bounce. Our updated front pole holder design is easier to use on the move.
