Whatever conditions come your way, our high performance clothing is designed with technology for all of your outdoor adventures. We choose our fabric and suppliers very carefully and have been working with all of our suppliers for many years. We know trust and trust that they think and act in a responsible way towards the environment.

Patented Design

The Dannah helmet compatible hood is patented design to provide the best protection in cold or wet weather. The cold flexible peak and hood adjustment secure tightly and provide total coverage without restricting movement or visibility. The adjustment and hood has been designed for ease of use in inclement conditions. Simply fastening the main zip is all that is required to achieve protection.

New Technology

High density thermo flexible peak

3D mannequin moulds to shape the hood

3D patterning to create optimum movement

Fabric consumption reduced to make the garment lighter

Porelle Dry

Porelle Dry is a waterproof, windproof and breathable microporous polyurethane membrane that is: light, flexible and durable.

The key feature of the Porelle Dry film technology is its dry feel when used in active apparel applications. This membrane allows air permeability preventing moisture to condense.

Porelle Dry films are produced by a unique novel coating process which enables the formation of a uniform microstructure. This ensures consistent waterproofness levels even after multiple washes. Some competitor products have irregular cell structures, with large pores which can inherently lead to failure causing a decrease in waterproofness and breathability.

Porelle technology provides a unique solution that keeps your body dry and reduces the accumulation of sweat, keeping you in a comfort zone. It is cooling when you are active and warm when you are at rest.

Porelle microporous membranes are based on a polyurethane chemistry and are constructed from many small interconnecting micro pores less than 1µm in diameter.

Porelle microporous membranes are hydrophobic (water hating) and resist the passage of water, even under high pressure. The membrane breathes by allowing sweat in the form of water vapour molecules to pass through the microscopic pores driven by greater heat, and the higher density of water vapour molecules from the inside of the garment.

The unique combination of microstructure and polyurethane chemistry ensures that Porelle microporous membranes remain waterproof in use, even after repeated washes.

“I have designed this three-layer application to endure the demands of mountaineers, ski mountaineers and serious outdoor enthusiasts. Garments made with 3 layer Porelle Dry are engineered for rough terrain while protecting against the extreme changing and unpredictable conditions presented to mountain athletes. Many athletes prefer this type of technology as it maintains a dry feel when working hard in the most testing conditions. I have worked very hard in testing garments and fabric to find a membrane which meets and copes with what myself and athletes expect.”

Jacket Review


I haven't even needed to open the pit zips yet, even when pushing a fast pace and wearing a heavy flannel shirt underneath. The recent weather in Britain has been fairly
nasty, and the Dannah jacket has stood up to it all easily



what a great Jacket with super friendly and helpful service. I've had a couple of walks in it over Dartmoor with sideways rain and for the first time ever returned home dry!!!

Jacket review


I've had this jacket for about 3 years now and can't fault it. It's done several military-style "Test Week Marches" in the Brecon Beacons and in Shropshire, usually in horizontal driving rain and hail. It's light, a comfortable, plenty
of pockets, great hood

Jkt Review


The hood is remarkable as I could still see well while staying dry. Brilliant, would highly recommend.
