02 / STUDIO NOTES
Protect the shell.
For Stormtech ST258, listed at 90gsm: Check coatings, lining and care instructions before applying heat. Some shells can mark, shrink or reject an adhesive. Test in a hidden area, and never assume a decoration leaves a waterproof garment’s performance unchanged.
