Rab Run

Frequently Asked Questions

• How do Rab trail running jackets balance waterproof protection and breathability for high‑output runs?

  Rab uses lightweight laminates like Pertex Shield 2.5L (seen on the Phantom Waterproof Pull‑On) to provide taped waterproofing with a stretchy, low‑bulk face fabric, while pieces like the Downpour Trail Light add seam‑sealed construction and waterproof zips for more durable protection. Strategic venting, DWR treatments, and stretchy two‑layer constructions prioritize moisture egress and pack compatibility so you can choose based on aerobic intensity and expected weather.
• What should I consider when choosing size and fit for Rab Skyline Tights and other trail running bottoms?

  Rab’s trail running tights use tailored, performance‑oriented cuts—women’s Skyline Tights have a thicker double‑layer waistband and drawstring for secure fit—so follow hip and waist measurements and factor in movement with a pack. If you plan to run with a hipbelt or layered base, allow a little room for mobility and test the tights with your typical pack and gaiters to ensure no bunching or seam pressure.
• How do Rab Sonic tees and zip shirts handle moisture and odor on long runs?

  Sonic tees and Sonic LS Zip use Motiv single‑jersey and mesh vent panels for fast wicking and quick drying, and Polygiene odor control to reduce microbial smells on multi‑day or long efforts. Micro‑seam stitching and bonded zips minimize chafe under pack straps while maintaining breathability during high output.
• How does the Phantom Waterproof Pull‑On compare to the Downpour Trail Light Jacket for ultras and mountain runs?

  The Phantom Waterproof Pull‑On prioritizes ultralight packability (about 3 oz) and stretchy Pertex Shield 2.5L construction for fast alpine runs where every gram matters, while the Downpour Trail Light focuses on more robust waterproofing with seam‑sealed zips and reflective details suited to prolonged wet conditions. Choose the Phantom for speed and minimal bulk, and opt for the Downpour when you expect sustained bad weather and need additional coverage and features.
• What storage and venting features in Rab shorts, vests, and jackets matter most for long‑distance mountain running?

  Look for stash pockets in waistbands and zippered chest pockets that sit above sternum height so gels and a phone are accessible without removing your pack, plus mesh venting or pit zips for on‑the‑move temperature control. Low‑volume hoods, seam‑sealed zips that don’t chafe, reflective accents for visibility, and fabrics that compress into their own pocket all help balance storage, ventilation, and ultralight packability.
