The material is cotton and wool. The zip is made of leather with an intrecciato design. Bottega hoodies made only of cotton have metal zippers, but this one has a leather zipper, giving it a luxurious feel. The silhouette is quite tight when zipped up, so it's recommended to wear it open as an outer layer. Thanks to the sturdy ribbing around the waist, the silhouette remains beautiful even when worn open. It's also useful as an inner layer for down vests or blousons in mid-winter. It's also recommended for casual layering under a coat. The sleeve ribs are long, so the sleeves are folded up in the photos. You can also wear them unfolded. The price may seem high compared to other Bottega hoodies, but please consider it as the comfort and silhouette are different from others.
