The three enemies: moisture, compression, sunlight
As a conservative storage choice, avoid putting a jacket away damp or keeping it tightly compressed long-term. The cited advice supports dry, protected storage; it does not quantify coating or adhesive deterioration, or establish that folding always cracks a laminate.
Arc'teryx's gear-care guidance is the most explicit published version of this: keep gear in a cool, dry, dark place; shells do best hung in a closet, protected from sunlight and moisture; hanging rather than compressed drawers or bins protects fabric performance and fit. Stutterheim's care guidance for its rubberised coats says the same for a different construction: store hanging, away from sunlight.
Before the jacket goes away
Clean as needed using the garment’s permitted method before long-term storage. Gore’s care advice describes contamination that can impair performance; this does not prove that every unwashed jacket will develop lifting tape in storage.
Dry completely, including the inside and the hood's folds. If the jacket's label permits tumble drying, a final low-heat cycle both finishes the drying and reactivates the DWR for next season — with the usual documented exception that persistent-beading garments such as SHAKEDRY must not be tumble dried.
An honest note on the evidence
We did not find dedicated storage procedures in the reviewed Gore, Patagonia and Rab care pages. That is a limit of the accessible documentation reviewed, not a claim that those brands publish none elsewhere. Arc’teryx and Stutterheim provide the specific hanging advice cited here.
