On drizzly days, we zip into the Sweaty Betty Pack Away Jacket before our training sesh. Lightweight recycled polyester keeps precipitation off our skin without weighing us down, and vents ensure air is flowing while we push our pace. When skies are gray, light is low, so Sweaty Betty added reflective stripes on the sleeves and torso to keep us visible to passing cars. And if the rain clears up, this jacket packs into its pocket for easy storage.
