Sugoi have produced a sub-100g jacket which they claims sets a new "gold standard for ultra-light weather protection".
The Helium is made from a woven polyester shell fabric and is said to be "exceptionally" wind and water resistant. To save weight, the designers went as far as replacing pit zips with tiny vents.
Sugoi say: "Lighter than a T-shirt and granting far greater weather protection than a windshirt, the Helium doesn’t stop short on advanced features. It boasts Scotchlite™reflective material on the length of the torso, as well as a full-length zipper and a rear zip pocket. With a drop tail and cutout notch at the back of the mock-turtleneck collar, the Helium is perfect for riding or running, or any activity where threatening weather looms."
The Helium jacket is available in men's and women's versions, in a total of seven colours. RRP is 79.90 euros (approx £73/US$108). A Helium vest (gilet) is also available, priced at 69.90 euros (approx £64/$94).
