An increase in capacity, upgraded materials and some added features make the 12L Responsiv Vest a great pack choice. With a really low weight, comfortable fit and improved storage this vest is ideal for longer races or events with more kit requirements.
Flagship of the Responsiv range. The Responsiv 12L Vest is an ergonomic and lightweight vest pack with 12 litre capacity and only weighs 200g, allowing you to pack your essentials for most runs and races in lightweight comfort.
Raidlight's 2019 Responsiv 12L Vest is a high performance vest pack. With lightweight materials and adjustment through dials this vest stays close and massively reduces any bounce while running. The upgrade to micro mesh on the rear panels of the vest have had a massive impact on increasing the comfort and performance levels too.
This 10L version is designed to cover you for the gear you'd expect to take on a regular Ultra through to a winter event where plenty of additional layers are needed through. It would be a bit tight for a multi day event or stage race even for the most well organised (and minimal) runners. It is a generous size for normal running events that simply require mandatory kit but it is still manageable since the overall weight is so low on the pack in the first place. The pack comes with two soft flasks with straws and these are great for drinking on the go so you don't need to break stride messing about accessing them. The pole holders on the front and back are great if you run with poles or take them for emergency use and the front holder is really handy if you want quick access. Although it's not the most durable material pack design is amazingly comfortable, practical and amazingly lightweight so they are ideal for serious runners and serious races.
