Thanks for contacting The Last Hunt and share some pictures.
After carefully review those photos, I believe this is a common misunderstanding among the clients. Basically, in order to reduce the product weight, more and more brands start using really thin but firmed fabrics for the winter coat, however, the disadvantage of those kinds of fabric is the insulation can be seen through which create some issues as you have seen with this product, visually you will see some darker spots covered on the jacket, but they are not stains, they are actually down under the fabric. This kind of misunderstanding started from the Arc'teryx SL series. In such a situation, we wouldn't consider the product as defective and no return and exchange would be offered.
Considering you had made some purchased in the past and this is a really expensive jacket, after discussing with our manager, we decide to offer a one-time exceptional return but at your cost. please let me know if you are interested in this option, I will share a return instruction for your after your confirmation.
i should not pay shipping
