Northwave Extreme H2O Light Jacket - 2020


The Northwave Extreme H2O long sleeved jacket features BIOMAP fabric which works and thinks with you. Strategically positioned stitching prevents any chafing when cycling. A combination of different fabrics provides enhanced breathability or more protection where it’s needed. Plus it ensures muscle compression for improved performance of active muscle groups. The bad-weather protection is provided by H2O flex membrane with exceptional stretch. Incredible super four-way stretch properties enable the membrane to mould perfectly to the cyclist’s body to ensure maximum freedom of movement and a snug aero fit. It provides a windproof barrier with up to 10,000 mm waterproof protection that retains body heat while rapidly wicking moisture to the outside of the fabric to create the ideal microclimate.

AndyChem I had previously bought the SS version and it is skin tight (I am 185 cm100cm chest/88cm waist/78kg)) but poor breathabilty made it only useful below ~10C. The LS version is redesigned and is more breathable due to mesh inserts down the sides and under arms. I ordered XL and it is almost too loose (for my taste). I wore for 2 hr ride in occasional drizzle @ 8C and was quite comfortable with a light (mesh) base layer.
