Building on the long-running Microlight series, this updated Windstopper version adds full windproofing and improved moisture resistance without losing the jacket’s balanced warmth-to-weight performance.
Rab says:
We’ve taken our bestselling lightweight down jacket, and super-charged it with added wind resistance provided by WINDSTOPPER® Products by GORE-TEX LABS. Warm, impressively windproof, yet breathable, it’s a go-to insulated jacket for year-round mountain use. Micro and nano baffles have been tactically placed to give you warmth, mobility, and breathability where it’s most needed. It has a slim, active fit allowing you to move freely, and is highly compressible when you need to stash it away. Whether you’re hiking windswept trails or projecting at a blustery crag, the Microlight Windstopper Hoody delivers an instant hit of heat.
Our Verdict
The Microlight Windstopper Down Hoody uses 146 g of 700-fill-power recycled down, encased in a GORE-TEX Windstopper shell. At 441 g (Medium), it provides dependable warmth for cold, exposed conditions while remaining light and compressible. The outer fabric blocks wind, though it produces a slight crinkly noise you would associate more with a shell jacket than a down piece.
Fit is slim but mobile, allowing efficient layering beneath. The hood has two face adjustments but no crown cinch, and cannot be tightened when fully zipped, which feels like a missed refinement in a winter jacket. The hem drawcords adjust from either side, and the elasticated cuffs seal effectively around the gloves. Two hand pockets sit behind the down for added warmth, one also doubles as a stuff sack, which I appreciate.
The combination of weather protection, warmth and packability maintains the Microlight’s strong pedigree, making this one of the most versatile technical down jackets in Rab’s current range.
