Kith Ivy x Wilson Warm-Up Jacket: Magma and the stretch-fabric choice

Magma is one of the updated colors in Kith Ivy’s Fall 2026 partnership with Wilson. The Classic Warm-Up Jacket in that shade, style wk00006r024001, is listed at $220 on the official US product page. The Ivy collection announcement set its release for October 5, 2026 at 11 a.m. Eastern, through Kith.com, the Kith app and the private members club. The garment page limits this offer to the US online store and Kith Ivy.

What distinguishes this jacket

Wilson’s design uses 77% nylon and 23% elastane, with perforated areas, a two-way front zipper, secure hand pockets and a bungee-adjustable hem. Kith lists UPF 50+ protection. That rating and the brand’s breathability description are manufacturer claims; they do not amount to independent wear testing or establish waterproofing.

The construction makes a useful comparison with the Kith Ivy Wool Varsity Jacket from the same release. That $695 garment uses a wool–nylon blend and quilted satin lining. Here, stretch content and ventilation are the defining specifications. For a collector following the Wilson collaboration, this is a distinct performance-oriented garment rather than a lower-priced version of the wool jacket. The fabric choice, not merely the chest branding, explains the different role.

Compare the function, then the fit

Another nearby comparison is the Kith for Cinelli Wind Jacket, a $305 cycling collaboration in polyester with a windproof membrane. The Cinelli description emphasizes packability and wind protection; the Wilson description emphasizes stretch and engineered perforation. A layer chosen for wind exposure and one chosen for movement around a court answer different questions. Neither page provides the comparative test results needed to rank their breathability or comfort.

Within the Ivy assortment, Wilson also offers a Classic Warm-Up Vest and coordinating shorts. The vest changes coverage by removing the sleeves, while shorts create another pairing without turning the jacket into a bundled set. Confirm each separate item and color if a matching outfit is the goal; a collection photograph is not a promise that every piece is included in the jacket’s price.

Before ordering

Kith calls this a relaxed layering fit with standard sizing and shows a 6-foot-3 model in Large. Use that as seller guidance alongside the size guide, rather than as a reason to apply sizing from an unrelated Wilson garment. The official photograph identifies the dark Magma version; other colors in the collection are separate choices.

The October 9 UTC listing showed final-sale terms and a two-unit customer limit. Those restrictions matter more to a sizing decision than an assumption of easy returns. No production quantity is disclosed, and listed size options do not establish permanent availability. Check the selected size on the live offer before paying. Kith’s clothing guide links the brand’s other releases.
