Iron & Resin Peak Wool Jacket – Heavyweight Men's Wool Shirt Jacket
The Iron & Resin Peak Wool Jacket combines the timeless insulating properties of traditional wool clothing with the rugged workwear aesthetic associated with Iron & Resin.
Officially named the Peak Shirt, this piece is substantially heavier and warmer than a conventional shirt. A heavyweight 13.5 oz wool-polyester shell combined with a fully quilted lining gives it the versatility of a shirt jacket, overshirt and lightweight cold-weather jacket in one.
Heavyweight 13.5 oz Wool Blend
The exterior is constructed from a custom 50% wool and 50% polyester blend weighing a substantial 13.5 oz.
This heavyweight fabric provides the traditional appearance and insulating qualities expected from wool clothing while creating a rugged layer designed for regular use throughout the colder months.
The result sits naturally between a classic wool shirt and a jacket – substantial enough to work as outerwear while retaining the clean silhouette of traditional workwear shirting.
Fully Quilted Interior
Inside, Iron & Resin adds a 100% quilted polyester liner for extra insulation. This transforms the Peak from a simple wool overshirt into a genuinely useful cold-weather layering piece.
Wear it over a T-shirt or work shirt during milder weather, or layer it over a sweater or hoodie as temperatures fall. Iron & Resin also specifically recommends the concept as an insulating layer beneath a rainproof outer shell.
Custom Iron & Resin Metal Snaps
Custom I&R metal snap buttons reinforce the rugged character of the Peak while providing a practical front closure.
Combined with the heavyweight wool fabric and classic shirt collar, the metal hardware gives the jacket the understated heritage workwear appearance that makes it easy to combine with denim, work pants and boots.
Dual Chest Pockets
Two functional chest pockets with top-entry flaps retain the utility character of a traditional work shirt. An internal locker loop at the collar provides an additional practical detail.
Shirt, Overshirt and Jacket in One
The Peak is particularly versatile because it bridges several traditional menswear categories.
It can be worn as a men's wool jacket, wool overshirt, shirt jacket, shacket or insulated wool shirt, depending on weather and layering.
This makes the Iron & Resin Peak an excellent option for men who want the simplicity of a classic shirt silhouette without sacrificing the warmth of a lined jacket.
Made for Fall and Winter Layering
The combination of heavyweight wool-blend fabric and quilted insulation makes the Peak particularly well suited to fall, winter and transitional weather.
Rather than relying on the technical appearance of modern performance outerwear, the Peak delivers warmth through traditional materials and straightforward workwear construction.
True-to-Size Fit
According to Iron & Resin, the Peak runs true to size. Customers who normally wear a consistent size can therefore select their regular size.
If you are between sizes or prefer additional room for layering, Iron & Resin recommends sizing up.
Rugged Heritage Style for Cold Days
The Iron & Resin Peak Wool Jacket is a versatile alternative to conventional winter outerwear. Heavyweight 13.5 oz wool-blend fabric, quilted insulation, custom metal snaps and practical chest pockets create a timeless layer for workwear, outdoor activities and everyday wear.
Whether worn as a jacket, overshirt or insulating mid-layer, the Peak delivers the rugged simplicity and durable character expected from Iron & Resin.
