Columbia - Trailborne™ 2.5L Packable Waterproof Jacket - Blue - Size L

The '2.5L' refers to the jacket's waterproof technology layer system. It signifies a 2.5-layer construction which is lightweight and packable, offering good waterproof and breathable performance for its weight.

This jacket is a shell and does not have insulation. It is designed to protect you from rain and wind. For cold weather, you will need to layer insulating clothing underneath.

The jacket is machine washable. Wash cold with like colors using a mild detergent. Do not bleach, and tumble dry low or hang dry. Avoid fabric softeners and ironing.

Omni-Tech™ is Columbia's proprietary waterproof and breathable technology. It provides a barrier against wet weather while allowing body heat and moisture vapor to escape.

The jacket has a regular fit. While it can accommodate layers, extremely bulky items might feel restrictive. It is best suited for mid-weight fleece or synthetic insulation layers.

The hood features peripheral adjustability. You can typically tighten it around your face using a drawcord or adjustment toggle located on the hood itself to ensure a secure fit and keep rain out.

Columbia Sportswear typically offers a limited warranty on their products against defects in materials and workmanship. Specific warranty details can usually be found on the Columbia Sportswear website or the product's original packaging.

Ensure all seams are properly sealed. Check that zippers are fully closed. If leakage persists, the waterproof membrane may be compromised and the jacket may need replacement.

This can indicate reduced breathability. Ensure the jacket is clean and free from debris. If wearing multiple layers, ensure they are also breathable. Excessive humidity can also contribute to this feeling.

Gently try to move the zipper up and down. If fabric is caught, carefully pull the fabric away from the zipper teeth. Apply a small amount of graphite (from a pencil lead) or wax to the zipper teeth to help it glide.

Check that the drawcords and Velcro tabs are clean and free of debris. Ensure they are not twisted or tangled. Gently pull or loosen the drawcords as needed.
