STIO Run

Frequently Asked Questions

• Which Stio jacket is best for rainy, high-output trail runs—Exploit Hooded Jacket or a reSphero anorak?

  The Exploit Hooded Jacket uses GORE-TEX Active 3L and fully seam-sealed construction, offering higher waterproof protection and breathability for sustained wet conditions and heavy exertion. reSphero™ anoraks are water‑repellent and quick‑drying, lighter and more packable, so they’re better for intermittent showers or when shedding sweat is the priority.
• How do Stio’s Terral Run Short and Shifter Shirt SS handle moisture and ventilation on hot or sweaty runs?

  Both pieces prioritize quick‑drying, moisture‑wicking performance—Terral Run Short uses stretch fabrics and ventilated designs for unrestricted mobility, while the Shifter Shirt SS is built for high‑sweat cycling and running with breathable, fast‑drying face fabrics. Combined with DWR finishes and strategic vents, they balance evaporation and comfort for sustained efforts.
• Are Stio run pieces packable enough for long missions, bikepacking, or travel?

  Yes, Stio designs run pieces like the Exploit Hooded Jacket to be ultra‑light and stuffable into a pack or waist belt, and many tops/shorts compress down small thanks to thin, quick‑dry fabrics. Technical pants and midlayers (like OPR Trail Pant and Trax Power Grid) are slightly bulkier but still chosen for low bulk-to-performance ratio on multi‑day missions.
• What size and fit should I choose for Stio running apparel?

  Stio tends toward a relaxed, performance‑oriented fit with built‑in stretch and articulation; choose your usual size if you want room for layering or a slightly relaxed feel, and size down for a race‑trim silhouette in pieces like the Terral Run Short. Use Stio’s chest/waist/inseam size charts and consider elastic waists/drawcords and articulated knees when planning for layering or cycling clearance.
• Which Stio layers are best for shoulder‑season runs and alpine missions?

  For cool, variable conditions pair a breathable insulating midlayer like the Trax Power Grid (Primaloft Gold Active for lightweight warmth) under the Exploit Hooded Jacket (GORE‑TEX Active 3L) for storm protection and vented breathability. Swap to Everlight Softshell or OPR Trail Pant for wind resistance and stretch on bikepacking or shoulder‑season approaches where mobility and weather resistance both matter.
