For 2013, Sportful has made their Hot Pack windproof jacket even lighter. The Hot Pack Ultralight is down to a barely-there 50g and can be scrunched into a size not much larger than a handful of gels.
It will be interesting to see how well this thing keeps the wind out with the fabric being so thin and delicate. It's made with yarns that weigh less than one gram per kilometre so the two square metres that are used to make the jackets measure almost 60km in length.
The fabric is weaved tightly to make it windproof and is given a water repellent finish. Weight is kept down with a 12g zip and printed logos, with seven vents, mesh-lined collar, and elasticated wrists and waists. It will retail in the UK for £120.
