Super lightweight geeks get in line. This smock weighs in at an astonishing 62g making it one of the lightest on the market so it’s no surprise why it’s so popular with svelte-minded climbers and runners with little room in their packs (or pockets). The Sonic is the answer to immediate wind protection on the hill with its durable material at the ready to deflect any strong gusts. Pertex Quantum is the magical material and this is DWR treated on the outside and has a Light PU coating on the inside, which work together to create a water repellant layer so you can stay dry from any showers. Thumb loop s help keep your sleeves in place when active and a draw cord hem lets you adjust the jackets’ fit to your liking. A stow pocket in the collar amazingly lets you roll the Sonic up and away into it for easy storage or transportation. A ½ zip lets you stay cool or warm depending on the weather. An amazing and futuristic step into gossamer jacketdom.
