As weird weather patterns shorten spring and stretch summer, outdoor brands are sprinting to update their seasonal playbooks. The latest must-have: ultralight jackets you can toss on and still wear through the height of summer.
Today’s lightweight windbreakers aren’t just transitional layers — they’re summer-ready pieces that balance function and style. Brands are using paper-thin, breathable fabrics with built-in sun protection and clean designs that slide effortlessly into everyday wardrobes.
Designers are embracing sheer, featherweight materials that practically disappear when you wear them. Bright, soft palettes — think mint, pastel pink, and icy blue — are replacing the old dark-and-serious outdoor look.
Thinner, lighter, and brighter: these evolved lightweight jackets reflect shifting seasons and how consumers live now, emerging as the defining trend for this outdoor season.
Eider is answering that trend with its SHEER series, combining ultralight construction and on-trend colors.
The collection uses 15D ultralight nylon with a powdery hand for a fresh, barely-there feel, plus a xylitol cooling finish so you get an instant sense of chill when you’re active.
Water-repellent treatment and strong breathability mean these pieces are comfortable from spring into midsummer. Pastel shades like mint, ice pink, and ice blue make them easy to style for both city and trail.
Eider’s Tour Lightweight Jacket pairs ultralight nylon ripstop with UPF50+ sun protection, so it stays cool and light under strong sun. It’s versatile enough for trekking, travel, or everyday wear and comes in kiwi, dark navy, and cream.
Black Yak is preparing for an earlier-than-usual heatwave with its Air Textured Jacket. The men’s version uses an ultralight single-layer fabric with a textured finish that prevents it from clinging to skin, keeping you feeling fresh.
The lining features Polygiene’s antibacterial and odor-control tech to keep things comfortable even after a long day of wear.
The women’s Air Textured Jacket keeps the same high-performance fabric but adds a loose, cropped cut for a fashionable silhouette. It’s offered in navy, light pink, and light yellow — perfect for bright summer looks.
K2 launched the Forest Jacket, a lifestyle outer layer that emphasizes natural vibes and practical design. The men’s Forest Jacket uses a lightweight nylon-cotton blend for easy comfort and includes a front zipper with a detachable hood so you can adapt to temperature swings. Available in midnight navy and natural beige.
The women’s Forest Jacket W mixes recycled nylon with cotton for a breezy feel. Its loose fit flatters various body types and comes in natural beige, chili, and pink.
Discovery Expedition rolled out gear aimed at active-wellness lifestyles. The women’s Pertex Running Windbreaker is built from Pertex lightweight ripstop for durability without bulk; a back-vent system boosts airflow and helps quickly release heat and moisture.
Mountia’s spring-to-early-summer lineup centers on light, breathable fabrics and cheery colors like ivory and pink to keep you comfortable and upbeat.
The women’s Tutti Jacket is a loose-fit piece with a watercolor floral print and perforated, breathable fabric that feels cool and airy on.
The men’s Pica Jacket uses a nylon-spandex blend for enhanced mobility. Practical details — color-block panels along seamlines, Velcro cuffs, and zip pockets — make it a comfortable pick for outdoor activity.
An Eider spokesperson said, “With the line between spring and summer getting blurrier, demand for lightweight, cooling jackets has surged. Pieces that combine practical features with everyday-ready design are standing out, and we expect them to become seasonal staples through midsummer.”
