The Kirkland Signature Men's Shirt Jacket is a versatile outerwear piece designed for fall and winter layering. Constructed from a heavyweight fabric blend of 92% polyester and 8% elastane with 400 GSM (11.8-ounce) weight, this jacket offers warmth and durability while maintaining flexibility through its 2-way stretch design.

This shirt jacket features a classic button-front closure with chest button pockets and side pockets for convenient storage. The design includes traditional button sleeve cuffs and is available in both tan and black color options. The fabric weight provides sufficient insulation to wear comfortably over just a t-shirt in cooler weather, making it ideal for outdoor activities or as an extra layer during colder months.
