Delamination is the separation of layers that were designed to stay bonded together in a laminated fabric. On a technical jacket it can show up as bubbling, rippling, peeling or areas where an inner membrane/backer no longer sits smoothly against the face fabric.
Delamination vs wetting out
They are different problems. Wetting out happens when the outer face stops beading water effectively and becomes saturated. The membrane can still be intact. Delamination is a structural bond failure between layers.
Why can laminate bonds fail?
Technical laminates age through a combination of use, contamination, flexing, heat, moisture and the natural life of adhesives and coatings. Manufacturers also stress the importance of cleaning compatible waterproof gear because dirt and body oils can compromise long-term performance.
Can washing cause delamination?
A correctly cared-for technical shell is designed to be cleaned, and major outdoor brands actively recommend washing suitable waterproof garments. Problems arise when a garment is already degraded, when the wrong products or temperatures are used, or when the fabric has reached the end of its practical life.
Can delamination be repaired?
Small tears in a technical shell can sometimes be patched, but widespread laminate separation is a different problem. GORE-TEX's own repair service states that products with excessive delamination — where lining material has separated from its layers — may be beyond repair. For a valuable garment, ask the manufacturer or a technical repair specialist before attempting irreversible adhesive work.
What to do if you spot it on a pre-owned jacket
- Stop and inspect the full inside surface.
- Photograph the affected area.
- Check whether the issue is isolated or spreading.
- Read the exact care label and identify the fabric.
- Consider manufacturer service or a technical repair specialist before washing or applying adhesive.
How to reduce avoidable damage
Keep technical outerwear reasonably clean, follow the garment-specific label, avoid fabric softener where the manufacturer prohibits it and do not store a wet garment compressed for long periods.
When buying pre-owned technical outerwear, inspect inner surfaces carefully on Stone Island jackets, C.P. Company jackets and Arc'teryx.
