Rab

Frequently Asked Questions

• What sets Rab apart from other technical outdoor brands?

  Rab combines British mountaineering heritage (est. 1981) with materials science and field-led design, emphasizing durability and performance in extreme environments. The brand pairs Pertex Quantum, Pertex Shield and GORE‑TEX shells with hydrophobic down, PrimaLoft or Polartec synthetics to prioritize warmth-to-weight, packability, and weather resilience while maintaining repairable construction and transparency about materials.
• How does Rab achieve a high warmth-to-weight ratio in jackets like the Microlight Alpine and Neutrino Pro?

  Rab uses high-loft hydrophobic down and targeted baffle construction in models like the Neutrino Pro, and lightweight Pertex Quantum face fabrics on Microlight-style pieces to maximize loft while minimizing bulk. Strategic layering, durable DWR treatments, and insulated hull designs maintain warmth even when damp, helping preserve insulation performance on alpine objectives.
• What should I know about Rab’s approach to durability and repairs?

  Rab designs products with reinforced stitching, bonded seams in high-abuse areas, and robust zippers and fabrics to withstand mountaineering and climbing use. The brand also supports longevity through an in-house repair service and repair-friendly construction details so garments and packs can be maintained rather than replaced.
• What is Rab’s Material Facts program and how does it affect product choices?

  Material Facts is Rab’s transparency system—accessible via a QR code on garments and sleeping bags—that discloses recycled content, manufacturing details, and fluorocarbon (PFC) status for each product. Introduced across apparel and sleeping bags since 2023, it helps shoppers compare sustainability attributes like recycled percentages and whether down or DWR treatments are fluorocarbon‑free.
• How does Rab’s fit philosophy work for technical activities like climbing and mountaineering?

  Rab favors an athletic, activity-specific cut that prioritizes freedom of movement and compatibility with harnesses, helmets, and packs, with articulated sleeves and longer hems where needed. Because construction varies by model, the brand recommends checking its size charts and product-specific fit notes to match intended layering and mobility requirements.
