What Our Gearhead® Experts Are Saying:"I’ve put the Lab GORE-TEX 3L Jacket through some truly nasty conditions, and it’s been bomber every time. The GORE-TEX membrane breathes better than any shell I’ve worn, so I don’t overheat on the skintrack. It’s built tough, with long pit zips and a removable powder skirt that make it easy to adapt to any mission."When the forecast is full of storm warnings and cold front squalls, we zip up the Flylow Lab GORE-TEX 3L Jacket and know we’re ready for whatever the mountain throws at us. Designed to be the pinnacle of Flylow’s outerwear, this jacket uses a GORE-TEX DV Expedition membrane to deliver exceptional waterproof protection while staying remarkably breathable on the uphill grind. From blower powder to rugged ridgelines, fully taped seams, waterproof zippers, and a burly 3-layer GORE-TEX shell stand up to punishing conditions. Articulated shoulders and sleeves ensure total freedom of movement, while 14-inch underarm vents dump heat when we’re booting to the next line. A removable powder skirt, helmet-compatible hood, and streamlined no-bulk cuffs complete this alpine workhorse built to handle seasons of abuse in the backcountry and beyond.
