When the weather can't make up its mind and every gram counts, the Outdoor Research Helium UL Jacket delivers ultralight protection that won't slow you down. At just 162g, this next-generation rain jacket features premium Toray Dermizax™ 2.75-layer waterproof technology that keeps you dry while maintaining the breathability you need for fast trail miles, peak bagging missions, or daily commutes. The wire-brim hood maintains its shape in howling winds, while the chest pocket cleverly doubles as a stuff sack so you can pack it down to almost nothing when blue skies return. Whether you're grinding out single track in variable conditions or need reliable weather protection for international travel, this ultralight hiking jacket proves that compromise isn't necessary when you demand both performance and packability in your outdoor gear.
