Totally windproof, waterproof, breathable & abrasion resistant. Waterproof Rating This is measured & expressed as Hydrostatic Head in millimetres (mm). To find out the Hydrostatic Head of a fabric the manufacturer will take a clear tube & clamp their material over the bottom end. They will then fill the tube slowly with water & watch to see how high the column of water can get before the material lets drips through. The higher the hydrostatic head, the better the water protection. The European Standard a fabric must meet to be classified as waterproof is a Hydrostatic Head rating of 1500mm, & on average, outerwear fabrics tend to have a hydrostatic head of 10000mm & above. Breathability Rating Measurement based on the Hohenstien test. Fabric is placed above a porous (sintered) metal plate. The plate is heated & water is channelled into the metal plate, simulating perspiration. The plate is then kept at a constant temperature. As water vapour passes thru the plate & the fabric, it causes Evaporative Heat Loss & therefore more energy is needed to keep the plate at a constant temperature. RETRET is the measurement of the resistance to evaporative heat loss. The lower the RET value, the less resistance to moisture transfer & therefore higher breathability. Hohenstein added a unique aspect to their testing. They had real people wear garments made with the fabrics of varying RET values & work out on a treadmill. They gathered comments of the testers & correlated this to the RET values of the fabrics & came up with a Comfort Rating System. RET 0-6: Very Good or Extremely Breathable
- Comfortable at higher activity rate.RET 6-13: Good or Very Breathable
- Comfortable at moderate activity rate. RET 13-20: Satisfactory or Breathable
- Uncomfortable at high activity rate RET 20-30: Unsatisfactory or Slightly Breathable
- Moderate comfort at low activity rate. RET 30+: Unsatisfactory or Not Breathable
- Uncomfortable & short tolerance time. RECCO Avalanche Rescue Reflector Using sophisticated radar technology, the Recco reflector forms the passive element of a 2-part avalanche search system. Ski resorts & mountain rescue teams carry Recco detectors, which send out a search signal, & the Recco reflector bounces back a directional signal that directs the rescuer straight to the reflector. More than 600 resorts & rescue services around the world use the Recco Rescue System as part of their immediate response.
