Equipe R Habu Winter Jacket S9

AIRBLOCK.888 is a three-layer membrane, and the number refers to the balance ASSOS strikes between blocking and passing vapour. The outer face takes road spray and holds the durable water repellent. The membrane stops wind and resists water while transmitting vapour. The inner layer protects the membrane from abrasion and moves moisture away from the skin. A jacket fails when the face fabric wets out, because a soaked face closes the vapour path the membrane depends on.

The insulation is placed rather than distributed. Thermal textile panels sit at the back, the lower front panel and the neck, where cold air reaches a rider in a race position and where a uniform layer would add bulk without adding warmth. The collar is cut to close against the neck without pressure, which is where most winter jackets lose heat in the first place.

The cut is ASSOS aeroFit, compressive and close, tested in the World Tour rather than derived from a training garment. Storage is three ramp pockets at the rear plus a front pocket for gloves, and a reflective strip runs across the lower back. Reference mass is 395 g in size medium.
