The Ostro Windproof offers packable protection for runners, cyclists and walkers.

For high energy activities such as running and cycling, it's important to have a lightweight windproof on hand for protection from windchill when at rest or in an emergency. For walkers, it is useful to have a protective layer that uses minimal space in your bag.

The Ostro Windproof uses lightweight Nikwax® Windproof fabric with a TX.Direct water-repellent treatment for shower protection. It compacts into its own pocket and combines with the Ostro Fleece for good weather protection in wet or cold weather.

The Ostro Windproof packs down small into its own pocket, has a helmet-friendly hood and good ventilation options.

  • Internal stuff pocket with loop for attachment for transportation.
  • Stowable helmet-friendly hood with low profile peak and dual adjustment.
  • Temperature control from ventilation zips that also provide access to internal pockets.

The Ostro Windproof is specifically designed to be compatible with the Ostro Fleece. Together these two garments create a versatile waterproof system.

Nikwax® Duology Windproof cuts windchill and protects your insulation but still provides excellent moisture vapour transfer

Nikwax Windproof FabricNikwax Duology Windproof uses a closely woven microfibre fabric that cuts windchill and protects your insulation whilst providing excellent moisture vapour transfer. A Nikwax PFC-free durable water repellent treatment deflects the rain.

Worn in combination with one of our Duology fleeces it traps still air in the fleece fibres to provide varying levels of insulation and waterproof protection depending on the weather conditions and activity.

Choose the Ostro Windproof for packability and versatility.

The Ostro Windproof is made from lightweight Nikwax® Windproof fabric with a PFC-free TX.Direct water-repellent treatment. It cuts strong winds and provides shower protection.

Combined with the Ostro Fleece, it forms a directional clothing system to protect from heavier rain and cold, making it a very flexible option for use across the seasons. It packs into its own stuff pocket to fit easily in your pack.

An adjustable "halo" hood moves without impairing vision and can be secured when not in use. The scooped tail ensures lower back protection for all activities. Subtle reflective flashes provide visibility in low light.

So the Ostro Windproof is a minimalist, lightweight, packable wind-resistant layer, versatile enough to wear year-round for a range of activities.

How will my Páramo Windproof outperform other windproofs?

Your Páramo windproof offers more versatility. Firstly because it is water-repellent and has a fully adjustable hood, it provides a good level of protection when worn as an outer layer, while offering exceptional breathability. Secondly, because in the worst conditions it can be worn over a Páramo Fleece to provide a higher level of weather protection. Therefore, it can adapt easily to a very wide range of conditions.

Páramo windproofs are extremely tough and durable, so suitable to be used in many different environments without damage.

  1. Helmet-friendly, securable "halo" hood with low profile peak and dual adjuster to move with you and not impair your vision.
  2. Ventilation zips on the torso give good temperature control and also allow access to two internal pockets.
  3. Stuffable into inside internal pocket with loop for easy transportation.
  4. Reflective flashes on sleeves, shoulders and hood to improve visibility in low light conditions.
  5. Scooped tail with hem drawcord for lower back protection.
  6. Excellent sleeve and shoulder articulation for full movement range during activity.
  7. Renewable water-repellency with PFC-free Nikwax® TX.Direct.
  8. Designed to be combined with the Men’s Ostro Fleece for very versatile weather protection.

Wanderlust testimonial“This jacket was clearly designed for the active traveller. Tiny, light and with good features at a competitive price.”
Wanderlust magazine, September 2017

“There are trips when full blown weather protection isn’t necessary or expeditions to environments where rain is minimal but equally the chances of being caught in debilitating foul weather remain. Over the last three summers I’ve travelled to the remote Arctic archipelago of Svalbard, backpacking solo over some of the roughest terrain and bearing an expedition weight of 30kgs which includes a rifle, ammunition and a camp warning fence to protect against the islands’ polar bears. With specialist equipment a must, every other gram worn or borne must be accounted for. Precipitation is low but equally the possibility of being caught in numbing rain remains.

Having used a Páramo Fleece Windproof system before, I was keen to try the Ostro Fleece and Windshirt during my last trip. The Ostro is a light system with a contemporary feel. Over the course of 10 days hard backpacking the Fleece kept me warm and dry in both brisk winds and light showers. One afternoon as I headed out along a remote coastline a heavy Arctic squall landed. The Ostro Windshirt thrown on top kept the worst of the rain at bay until I was able to throw up my shelter.

What the Ostro brings to my clothing options is a light and flexible clothing system. The Fleece is warm, rain resistant and wind tight but takes little room stowed in the pack. It’s a contemporary design which looked as good in the Airport Lounge as it functioned out on the Arctic tundra. Throwing the Windshirt on pushed its capability considerably and it offers a good three season use for days when full rain protection is not a must. Both garments wore well over 10 days of carrying a very heavy pack and I’m convinced of their long term durability.”

The Ostro Windproof combines really well with the Ostro fleece. I bought it in indigo blue, which is a lovely subdued colour. It has two pockets and one additional pocket for packing the windproof into. The size all packed up is just a touch bigger than a can of coke. The loop to attach it to a belt or harness is great. The hood is so much better than you would normally expect on a windproof, keeping the weather out in a superb fashion. I happily use the fleece/ windproof combination in light rain. I haven't yet been brave enough to use it high up in the mountains with wind and rain.

In what weather conditions can I use my Ostro Windproof Jacket?

Used alone, the windproof, water-repellent fabric of the Ostro Windproof provides ideal protection against wind and light showers. Its breathability and ventilation help prevent overheating.

In colder, wetter or more changeable conditions the Ostro Windproof can be combined with the Ostro Fleece to give good waterproof and insulating performance, making this a very versatile and useful three-season windproof.

Which garments should I use with my Duology Windproof for optimum performance?

We recommend combining our Windproof garments with the relevant Duology Fleece for varying levels of insulation and waterproofing depending on the weather conditions and activity. The fleeces come in two weights to suit different requirements. Click here for more information.

A Grid baselayer worn underneath a windproof is an excellent combination in warmer conditions when less insulation is required.

In extremely cold conditions our Torres overlayers are designed to be worn on top of your windproof.

Páramo clothing does not rely on hazardous PFC treatments for water repellency.

Working closely with Nikwax, we have developed a pioneering PFC-free treatment for our fleeces, waterproofs and windproofs. Recent studies show that PFC’s are persistent in the environment and are damaging to human health; which is why Nikwax waterproofing solutions are water-based, use no harmful solvents or propellant gases, contain no damaging PFC’s and are not tested on animals.
