The Ostro Fleece is for active people who swap between activities and environments.

Unpredictable weather can cause a predicament for backpackers, trail runners, cyclists and walkers. It is a challenge to pack light and still be prepared for all possible conditions.

The Ostro Fleece offers a solution: worn on its own, it is highly breathable, provides warmth, and repels moisture thanks to a PFC-free water-repellent treatment. When conditions turn windier, wetter or cooler, the Ostro Windproof is quickly added on top for good weather protection.


The Ostro Fleece provides both functionality and comfort.

  • Simple, close-fitting "Ninja" hood that fits well under a helmet.
  • Five pockets, all lined with mesh Pump Liner® to help move moisture.
  • Off-centre zip prevents discomfort around the mouth and avoids bulk when layered.

The Ostro Fleece is specifically designed to be compatible with the Ostro Windproof.

Together these two garments create a versatile waterproof system.


Nikwax Duology Fleece is lightweight, highly wind resistant and has a durable water repellent finish suitable for use in light showers, protecting against mist and drizzle.

Nikwax Duology Plus Fleece is a thick pile, directional fleece offering superior insulation and high levels of water repellency. It actively pushes liquid water outwards, keeping you dry even in poor weather conditions.

Nikwax Windproof FabricA Duology windproof cuts windchill, deflects rain and traps still air in the fibres of Duology fleeces to provide varying levels of insulation and waterproofing depending on the weather conditions and activity. The fleeces come in two weights to suit different requirements.

How will my Páramo Duology Fleece outperform other mid-layers?

Many other mid-layers are designed simply to provide extra insulation when worn over a baselayer. Duology fleeces offer more versatility.

What users say...


“The Ostro Fleece has become my absolute favorite fleece. Other fleeces were often too thick for me and I got into a sweat relatively quickly. The Ostro Fleece is a great windbreaker and withstands light drizzle. In combination, I always have the Ostro Windproof Jacket with me. It does not take up much space and, with the fleece, I have a complete waterproof system. An inside pocket would be great, but otherwise a near-perfect fleece!“ 

Fabian Baumann, August 2019


“If smartphones have supplanted ordinary phones, then the Ostro is a ‘smartfleece’. To touch (or rather stroke), the Ostro is soft and this furry fabric does more than just feel nice. It was developed by Nikwax to be water repellent and wind resistant. With its athletic fit and longer arms, this is a light and versatile fleece for optimum mobility and comfort in the extremes, designed to work in combo with the Ostro Windproof. And as with all Páramo kit, it boasts superb eco and ethical credentials.”

Country Walking, June 2018


“At 379g, this is a light fleece. It's not too warm nor too cold: it just works. The unique bit: it feels....well, like there's something on it . That's because there is: a PFC-free water repellency, making it half useful in rain. VERDICT: A useful addition to my take-on-every trip kit list.”

Trail Magazine, October 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.”

I have had the Ostro Fleece and Windproof for about a year. I love the combo as it is fantastically warm for its weight and particularly weather resistant.

I have both fleece and windproof in Medium. I am 5ft10  (178cm) in height, and relatively slim. The length of the fleece is perfect. The style is pretty slim, which I really like. The sleeves are too long. I have the fleece in a light blue, which is very finely speckled with black. The colour hides any dirt pretty well, essential when out and about in it for several days. The fabric is really soft which makes it really comfortable. I have also found it to be extremely breathable. There are five pockets and the size of all of them is good. Two outside hand warmer pockets have zips. The backs of these pockets are sewn up to make internal drop pockets. There is also a good sized zipped internal chest pocket. The fleece packs up very small but what is surprising is the warmth that it gives. In spring/summer/autumn I will happily wear a base t shirt and the fleece, adding the windproof when it is damp. In deepest winter I wear a long sleeved base, then the Ostro, all underneath the Helki jacket. I really like Páramo hoods. When you pull the soft fabric around your head it blocks the sound of the wind and also the cold. On a bad weather day this will really improve your mood. I bought the Ostro very much for the versatility of its hood and it is really snug on my head.

In what kind of weather conditions can I use my Ostro Fleece?

Worn alone, the Ostro Fleece will protect against mist or drizzle and provide insulation.

Combined with the Ostro Windproof, it will give good waterproof protection and additional warmth for cooler, wetter conditions.

Equally, it forms an effective midlayer for extra insulation under an Analogy waterproof in cold conditions, making it a versatile and useful year-round fleece.


Which garments should I use with my Duology Fleece to get optimum performance?

We recommend combining our Fleece garments with the relevant Duology Windproof 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.

Any Páramo baselayer worn underneath a Duology fleece will enhance the performance of the combination, keeping you dry and comfortable when working hard.

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


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.
