Reliable warmth and weather-resistance in a slim, lightweight design.

Rab's Microlight Summit is a modern lightweight technical jacket, made using hydrophobic goose down inside a Pertex Quantum Infinity Weave outer shell.

It's a great outer layer for cold, damp conditions and its streamlined profile makes it a comfortable midlayer under a waterproof shell in extreme weather.

With revolutionary Pertex® Quantum Infinity Weave™ ∞ fabric, baffles aren't sewn or glued but woven into the fabric during its manufacture, so the jackets are neater and more durable, with enhanced wind and weather resistance when compared to fabrics with traditional stitched-through baffles.

  • Stretch nylon cuff allows sleeves to be kept rolled up
  • Helmet-compatible hood with laminated brim and flexible polymer peak
  • Internal stretch bound hood seams reduce hood volume when worn without a helmet
  • Internal stretch hood gaiter seals out wind and improves fit around face

  • YKK VISLON harness-compatible hand pockets

WAIST: Measure around the smallest part of your waist (natural waistline).

HIPS: Stand with your heels together and measure around the fullest part.

INSIDE LEG: Measure from the top of your inner leg, along the inside seam to the bottom of your leg.
