Oiselle Women's Vests

Frequently Asked Questions

• How should I size an Oiselle vest if I plan to layer over a base layer and a thin midlayer?

  Oiselle vests generally run semi-fitted to cropped—stick to your usual size for a streamlined layering fit over a base layer, and consider sizing up if you plan to wear thicker midlayers or prefer more room for mobility. For reference, the So Fly Puffer is about 21.5" center back in size S while the Reflective Vigor Vest is ~23.75" center back in size S, so length and intended fit (cropped vs. hip length) can affect your choice.
• When should I choose the Firecracker Insulated Vest or So Fly Puffer over a non-insulated wind vest for cold-weather runs?

  Choose insulated pieces like the Firecracker Insulated or So Fly Puffer for low-intensity runs, cool-wind starts, race warm-ups, or hikes where retained warmth matters—Primaloft Thermoplume provides feather-free loft and performance when damp. Opt for a non-insulated wind vest (Pertex shell options) when you expect higher exertion, need maximum breathability, or want the lightest packable layer for variable efforts.
• What running-specific features should I prioritize when picking an Oiselle vest for low-light, packable runs?

  Look for reflective mesh panels or logos for visibility, a full zip for ventilation control, and a packable design that stows into a pocket with an elastic carry strap for hands-free runs. Also prioritize zippered pockets sized for gels/keys (2 hand pockets, or 3–5 pockets on some puffers), a bungee-adjustable hem for fit, and a stowable hood if you need extra coverage on transitional-weather outings.
