Reigning Champ Run

Frequently Asked Questions

• What makes Reigning Champ’s Deltapeak™ T‑shirts a good choice for long, hot runs?

  Deltapeak™ is a Japan‑made synthetic mesh polyester by Teijin that’s ultra‑lightweight, highly breathable, and quick‑drying, with built‑in moisture management and anti‑microbial odor control. The soft, low‑friction knit minimizes chafing and provides subtle stretch and UV protection, making Deltapeak™ T‑shirts and tanks ideal for endurance runs and hot‑weather training.
• How do the 5” Running Shorts compare to the 7” Training Shorts for different types of runs?

  The 5” Running Shorts are perforated and use an engineered knit liner to prioritize long‑distance comfort, ventilation, and minimal chafe, while the 7” Training Shorts use 4‑way stretch nylon and mesh hand pockets for more versatile, higher‑mobility training and shorter runs. Choose the 5” for sustained road or trail mileage and the 7” when you want extra coverage, pockets, and rugged stretch for interval or cross‑training sessions.
• What kind of weather protection and breathability does the Running Jacket provide?

  The Running Jacket pairs Ripstop Nylon with a breathable mesh back to deliver water‑repellent and wind‑resistant performance without sacrificing ventilation, making it suited to variable conditions and high‑output efforts. Its body‑mapped construction and movement‑oriented cuts help maintain mobility during hard efforts while shedding light moisture and wind.
• How should I pick the right Reigning Champ fit and size for running?

  Reigning Champ’s performance fit is tailored for mobility—about 1″ slimmer in the body and 1.5″ shorter in length—featuring underarm gussets and semi‑raglan sleeves for full range of motion; other offers include Slim, Standard, and Relaxed cuts. Check the brand’s fit guide and use the example sizing (size Large commonly fits a 5′11″, 165–170 lb runner) as a starting point, and size up if you prefer extra layering room or a less tapered silhouette.
• Are the Team Jacket and Pant a good option for cross‑training and mixed‑weather workouts?

  Yes, the Team Jacket and Pant use two‑way stretch Nylon Oxford with a DWR moisture‑shedding finish and abrasion‑resistant construction, designed for multi‑sport training on and off the field. They balance durability and mobility for dynamic sessions and serve well as an outer layer in damp or breezy conditions while still allowing layered moisture management underneath.
