Is the Microlight Alpine warm enough for winter?

It works as a midlayer in winter or as an outer layer in cool, dry conditions. For deep cold or wet weather, wear it under a shell.

How does it compare with the Patagonia Down Sweater?

The Rab has a slimmer, more climbing-oriented cut and packs into its pocket. The Patagonia has a roomier fit and a more casual look.

Does it fit true to size?

It runs slim. If you plan to layer a fleece underneath or have a broad chest, size up.

No. The face fabric is water-repellent and handles light snow or drizzle, but it is not waterproof.

What is it filled with?

It uses down and feather insulation, which gives high warmth for its weight but loses loft when wet.

Can it pack into its own pocket?

Yes, it stuffs into one of its hand pockets for compact storage.

Our take on the Rab Men's Microlight Alpine Jacket

The Microlight Alpine is Rab's lightweight down jacket, built for alpine climbing, hiking and cold-weather layering. It uses recycled nylon with a water-repellent finish and down insulation, packs into its own pocket, and has a slim, athletic cut. Reviewers rate it highly for warmth-to-weight and packability, though the slim fit and light face fabric draw some complaints. It competes with the Patagonia Down Sweater and Arc'teryx Cerium, offering a more technical, climbing-oriented cut than the Patagonia.
