1 item left


Version 3.0 of the Responsiv 18L shares all the features of Raidlight's best selling Responsiv 12L, but with extra capacity and a secure zipped rear compartment.

Go Longer, Further and Harder with the Responsiv 18L. Raidlight have made this race vest for people who need to carry a little more equipment, maybe on a longer Ultra, a FKT attempt or a winter challenge when more clothing might be required. This trail running pack is perfect for long races with less aid stations and expected poor weather!


Some runners struggle to get everything they need into the Responsiv 12L for longer races with larger mandatory kit lists, or the need for more durable clothing and equipment which adds pack size and a bit of weight. The Responsiv 18L is perfect for those bigger and longer races and big days out.

Accessible Pockets:  Up front there are 2 bottle pockets, 2 stretch pockets which fit a surprising amount of food! Plus a zipped pocket which will fit most phones. To the rear there is another accessible zipped stretch pocket. The main compartment is zip accessed through the top and the side, is hydration reservoir compatible and has an internal zip secure pocket. If that isn't enough pockets... we added an additional stretch pocket on the rear.

Eco-Responsible: In line with our commitment to environmental responsibility, the fabric of this product meets the standards of the Oeko-Tex certification. STANDARD 100 by OEKO-TEX® is one of the world's best known labels for textiles tested for harmful substances.
