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.

12L V2 . Get one

Now I have the full set. 12L, 18L and 24L. Just a sucker for Raidlight I guess. But the Version 2 of the 12L is fantastic. Things just keep improving.

Un buon prodotto

Lo zaino ha soddisfatto le mie aspettative. Molto comodo e avvolgente. I tempi di attesa della spedizione si sono protratti un po' troppo a causa di un problema con l'indirizzo di spedizione e forse le vacanze natalizie. Ho contattato l'assistenza clienti che mi ha tempestivamente risposto e rispedito lo zaino che è effettivamente arrivato dopo qualche giorno.

Amazing Engineering

I used the first version for 3 or 4 years and loved it. However the V2 is vastly improved on that - the zip pockets provide safe options for your phone. The fit around your neck is also wider and does not rub as much. It feels a little more stretchy, but still giving great structure. The plackets are perfectly sized for all you need on long runs, but also shrink down when you don’t need as much equipment. All and all, these are amazing packs and I use it every day, showing great durability! I think they are the best on the market! The only thing I am not sure about are the bottles. The valves make it very hard to get water out and feels like you have to suck very hard. I need to play around with it, but do prefer other bottles that are easier to use. Thanks for a fantasy product!

Responsiv 12L V2


Body hugging race vest design, sticks to your back like a limpet!

Twin elastic chest straps give freedom to breathe while at the same time avoiding bounce.

The vest part of the pack uses highly breathable monofilament mesh, allowing heat and perspiration to escape.

The freelock micrometric dial adjustment system on the sides of the pack allow you get a perfect fit, even on the move, as softflasks on the front empty as you drink the dials can be turned to maintain perfect tension. Set your front straps to the width you want, then use the dials to adjust fit.

Responsiv 12L V2


With a total of 9 pockets, 6 that can be reached on the move, you can store lots of items to hand, 2 for hydration on the front, 2 stretch storage for food and more, 1 zipped front and 1 zipped lower rear for secure items. The main rear compartment is hydration compatible for a reservoir and there is an internal zipped security pocket. The external stretch rear pocket can easily hold a damp jacket and more. Plus pole holders front and rear and the ability to use our TRAIL QUIVER for additional storage. This is a truly versatile 12L trail running pack.
