From the Bog Dog team:
Stay dry in the heaviest rain with the STORMSHELL, a high performance waterproof running jacket built for intense training and racing.
The STORMSHELL FZ is made with Pertex Shield 2.5 layer waterproof fabric. This premium material is water repellent to 20,000mm, which means it should keep you dry in the heaviest downpours and snow. The 20,000mm HH rating means that if a column of water was placed on the jacket's fabric, it would need to be 20 metres tall before the water would penetrate it! Alongside the waterproof fabric, the STORMSHELL FZ also benefits from fully taped seams, which means it meets any racing requirements, where you need to carry a waterproof jacket.
As good as the STORMSHELL is at keeping water out, it's also brilliant at letting it out too. The jacket is highly breathable, allowing sweat to exit the shell to help you manage your body temperature during intense exercise.
When needed, you can pull up the adustable hood to protect your face and ears from driving wind and rain. The hood has a wire-reinforced peak, designed to keep the water out of your eyes and has enough space for you to wear a head torch underneath too.
The STORMSHELL is super lightweight, and packs down small into its own pocket when not in use - perfect for stashing in a race vest or waist pack. The jacket's pocket is also useful for storing valuables in as you run.
Made with cutting-edge materials, and built specifically for the demands of long distance running in wet weather, the STORMSHELL V2 is the dependable jacket to keep you protected in the wind and rain.
