Rab Men's Vests

Frequently Asked Questions

• What technologies do Rab use in men's vests like the Mythic and Microlight?

  Rab uses body-mapped insulation with micro- and nano-baffles to concentrate 700FP–900FP down around the core while trimming bulk under the arms, plus stitch-through baffle construction for light durability. Typical shells are recycled Pertex Quantum with a DWR finish, down is treated with a fluorocarbon-free hydrophobic process, and details include YKK zippers and adjustable hems for a close, secure fit.
• How do I choose between a Rab down vest (Microlight or Neutrino) and a synthetic vest like the Xenair?

  Choose down (Microlight, Neutrino, Mythic) when you prioritize maximum warmth-to-weight and packability—fill power in these models ranges from about 700FP to 900FP. Pick a synthetic option like the Xenair if you expect sustained damp conditions, since PrimaLoft-style fills retain loft and insulation when wet and dry faster than untreated down.
• How does the Mythic Vest compare to the Microlight and Neutrino Down Vests?

  The Mythic focuses on a higher-performance, body-mapped approach using 900FP down in core areas for superior warmth-to-weight, while the Microlight uses 700FP down and is engineered to be extremely light and packable (around 11.2 oz/318 g for a large, with ~118 g of insulation). The Neutrino sits between them with balanced insulation weight (about 120 g) for steady warmth and everyday alpine use.
• What sizing and fit should I choose for alpine climbing versus casual cold-weather layering?

  For active alpine climbing and fast uphill moves, pick a close-fitting or alpine-cut vest (models like the Mythic and Microlight have snug collars and tailored cuts) to minimize bulk and preserve mobility. If you plan to wear a thick midlayer underneath, choose a standard cut or size up; all Rab vests typically offer adjustable hems and elasticated armholes to tune fit across sizes XS–XXL.
• Which vest features matter most for climbing, backcountry skiing, and cold-weather hiking?

  For climbing prioritize low bulk, freedom of movement, and harness-compatible or low-profile pockets plus body-mapped insulation for mobility. For backcountry skiing favor high fill-power down in core zones and excellent packability (Mythic or Microlight) to balance warmth and weight. For cold-weather hiking pick breathable Pertex Quantum fabrics with DWR and consider synthetic Xenair if you expect prolonged wet conditions.
