About Material

  • BLOCVENT® is a brand mark of up-to-date laminates of a non-porous hydrophyle membrane made in Japan by the TOYOTA Company. This membrane, thanks to continuous development, progressive technology and latest knowledge used with it, gives the BLOCVENT® line extraordinary abilities.   
  • BLOCVENT® is intended for extreme conditions and physically hard and longtime activities. The wear made from it is suitable for expeditions, mountaineering, skialpinism, alpine hiking, cycling, trekking, winter sports etc.
  • Thanks to its non-porous character, BLOCVENT® is very flexible and able to recover even after extreme stretching, and it keeps its outstanding qualities even after longtime using and in very low temperatures.
  • BLOCVENT® materials possess an outstanding water column, which means high ability of resistance against getting wet, extraordinary breathability and wind-resistance. BLOCVENT® is easy to maintain and is environmentally friendly. Its unique chraracter is the efficiency of the material according to vapour-permeability : with encreased activity this parametre is encreasing and the material becomes more breathable.
  • All BLOCVENT® materials have water-resistant DWR treatment .   
  • BLOCVENT´s maintaining is very easy and it is environmentally friendly.


Used and tested for many years, a two-layer laminate with outstanding qualities and ideal proportions between price and service. The material has been developed a long time and at present it offers low weight and high surface resistance. According to its construction a net lining has been added protecting the membrane from inside. 

  • Waterproofness: min. 20 000 mm H2O

BlocVent PRO  

A newly developed three-layer material with membrane offering even more breathability than before. The high elasticity the material is offering now guarantees comfort and free movement so that you can only concentrate on the affort. The products made from this material should be used in the hardest conditions when high level of waterproofness as well as high breathability are needed. 

  • Waterproofness: min. 25 000 mm H2
  • Breathability: 40 000 g/m2/24 hrs (norma JIS L1099)
  • Use: mountaineering, climbing, skialpinism, hiking



Products made from BlocVent must be well treated to keep their outstanding qualities. The treatment of such materials is very easy, you should only keep several main rules. If so, your products from BlocVent will be of long and good service.

  • Use usual wet washing in the washing machine with program Fine or wash by hand.  

  • Membrane wear is recommended to wash separately from other wear and one by one, if possible.

  • When washed in the washing machine, everything that could damage the material mechanically should be removed.  

  • Be careful about forgotten things in the pockets or in the washing machine.

  • Close the velcros on the wear carefully.  

  • Keep the temperature recommended by the producer, usually 30°C. Don´t rely on your subjective feeling.

  • Use entirely detergents, best liquids, intended for these materials. We recommend Fibertec PRO WASH.
  • Do not add any other ingredients (bleacheries, fabric conditioners...) Chemical cleaning not allowed.  

  • After washing rinse carefully to remove the smallest remains of detergents and dirt.

  • After washing get the wear immediately out of the washing machine and start drying.  


All BlocVent materials have DWR (durable water repellent) treatment, which makes a water-repellent layer on the surface preventing water to penetrate the material. You can see little drops running off the material, not being absorbed. The product being used the effectivity of the waterproof layer is getting worse and water starts penetrating. The user can feel wet and thinks that water is running into, although it is not true. The breathability is getting lower as well. Therefore it is important to keep water-resistance in good stand, which is not difficult if recommended detergents are used.  To return water-resistance we use for instance Fibretec Blue Guard.

Important Warning: Don´t wring the wear. You could damage it irreversibly. Let water trickle out of the hung wear at room temperature. Don´t dry in the sun. Don´t leave the wet wear folded for long.
