Lightweight Running Windbreaker – Packable Hooded Wind Jacket for Functional Fitness (Unisex)

Outdoor intervals, the walk to the venue, a cool warm-up before your wave: this lightweight running windbreaker blocks the wind, weighs next to nothing and packs down small enough to stuff in a gym bag.

Features

• Ultralight wind shell: thin polyester fabric, about 4.9 oz (140 g).
• Hood and full-length zip for quick on and off between sessions.
• Elastic cuffs and hem that seal out the breeze and stay put while you run.
• Side hand pockets.
• Packable: rolls into a small bundle for your bag.
• UPF 50+ rated fabric (supplier rating).
• Plain, logo-free design. Unisex fit.
• Sizes S–4XL. Colors: Royal Blue, Neon Lime, Navy, Rose Red, Sky Blue, Light Pink.

This is a wind shell, not a rain jacket: it isn’t sold as waterproof.

Size Guide

Unisex, Asian sizing. Sizes run smaller than typical US sizing, so we recommend ordering one size up from your usual US size. Women may want their usual US size or one up for a looser fit over layers. We don’t publish garment measurements for this jacket yet; if you’re unsure, email support@gridrox.com before ordering.

Layer it over the women’s seamless long-sleeve training top or the men’s quick-dry training tank top, and keep the oversized terry training hoodie for after. Racing in the cold this season? Our Denver and Nashville guides cover the walk to the venue, and what to wear on race day covers the rest.
