Waterproofing for the most active people. The Interstellar has excellent stretch and breathability making it a great option for anyone who doesn't want the weather to stop you getting out. Whether that's heading into the mountains or simply around town this jacket has you covered.

Outdoor Research says:

The lightest, most breathable hard shell with real stretch that keeps you dry without keeping you constricted. With dynamic reach underarm panels allow total mobility, above-the-harness pocket placements, and a fully adjustable helmet-compatible hood that offers versatility across different activities and seasons - the Interstellar tips the scales at 11.6 ounces without compromising on functionality. Featuring exclusive AscentShell™ technology to give you unprecedented stretch and moisture management wrapped in a completely stormproof outer layer.

Outdoor Research's Interstellar Jacket gives you a great level of protection from the wind and rain but its extremely high level of breathability and stretch in the material that sets it apart. This is a great all round jacket with design features and a style that make this jacket stand out when you're around town or up in the mountains. The high level of stretch and breathability mean that this is great for walking, fast-packing and more intense activities such as mountain biking but I found that trail running stretches it's limits in this sense.

The Interstellar provides a decent amount of features for this weight and price. A fully adjustable hood with stiffened peak means you can keep the worst of the weather out even when the wind and rain are swirling around you. The hem and cuffs are also adjustable and added to the stretchy, soft feel of the material make this one of the most comfortable hardshells I've ever worn.
