Columbia Trailborne 2.5L Packable Waterproof Jacket - Brown - XXL

The '2.5L' refers to the laminate construction of the fabric. It indicates a 2-layer fabric with a half-layer (a protective print or coating) on the inside, offering a good balance of waterproofness, breathability, and packability without needing a separate inner lining.

This is a shell jacket designed primarily for waterproof and windproof protection. It is not insulated. For winter conditions, you will need to layer it over warm mid-layers such as fleece or down to achieve adequate warmth.

Locate the internal pocket (often on the chest or side). Fold or stuff the jacket into this pocket until it fits snugly. Some models may have a specific design to facilitate this.

It is recommended to use a mild detergent and avoid fabric softeners, bleach, or harsh stain removers. Fabric softeners can clog the pores of the waterproof/breathable membrane and reduce performance.

'Fully seam-sealed' means that a waterproof tape is applied over every seam inside the garment. This prevents water from leaking through the needle holes created during the sewing process, ensuring maximum waterproofing.

The hood typically has drawcords at the back or sides that allow you to tighten it around your head for a snugger fit. The brim also helps to keep rain away from your face.

Ensure the DWR (Durable Water Repellent) coating is intact. Wash the jacket according to care instructions and consider applying a DWR re-treatment spray. Check that seams are still sealed.

Ensure underarm vents are open during strenuous activity and that you are not overheating. Check that the fabric is clean, as dirt can impede breathability. Make sure you are not wearing layers that are also non-breathable.

Gently try to work the zipper back and forth. Ensure no fabric is caught in the zipper. If it remains stiff, a small amount of graphite (from a pencil) or a specialized zipper lubricant can be applied to the teeth.
