Klim Ostara Long Sleeve Shirt

The Ostara Long Sleeve Shirt is a lightweight, moisture-wicking performance women’s shirt built for long days outdoors and active use. It blends comfort, stretch, and simple performance features in a casual long-sleeve silhouette.

🧵 Key Features

• Lightweight moisture-wicking fabric: Made from a polyester/spandex jersey knit that helps pull moisture away from your skin and dry quickly.

• Engineered 4-way stretch: Allows freedom of movement in all directions, so the shirt moves with you when hiking, riding, or traveling.

• Comfort seams: Flat seam construction and offset shoulder seams minimize bulk and reduce chafing for all-day wear.

• Regular fit with set-in sleeves: Provides a comfortable yet not overly snug silhouette that works well as a standalone top or layering piece.

• Fabric composition: Typically 94% polyester and 4% spandex with a lightweight feel (~3.5 oz/sq yd; ~121 gsm).

👌 Performance & Uses

This long-sleeve shirt is ideal for adventure days, travel, trail outings, or everyday wear when you want breathable performance without bulky layers. The stretch and moisture control make it comfortable on its own in mild weather or as a base layer under a jacket in cooler conditions.
