A new take on our best-selling 40 Series—now with the added function of clean, low-profile back pockets. The 45 Series delivers the same sleek fit, premium Italian fabric, and performance-driven comfort you count on, with just a touch more everyday utility.

Designed to move seamlessly with you in and out of the saddle, the 45s offer a smooth, flattering silhouette that never loses its structure. Our signature quick-dry, ultra-breathable knit keeps you cool under pressure, while the minimalist back-pocket design adds storage without bulk or bounce.

Whether you're training, showing, or living in your breeches between rides, the 45 Series brings elevated practicality to our most loved fit—without compromising the streamlined, sport-ready feel Struck is known for.

The 40 Series breech is made with Repreve Recycled Nylon Fabric. Using recovered yarn waste as a replacement for fossil fuel-based raw materials, this secular fiver reduces global dependence on virgin petrochemicals, without sacrificing the strength, durability, and performance of lightweight stretch nylon fabrics.

Our 40 Series breeches are a mid-rise. Made to hug the body, they fit similar to tights. All of our 40 Series breeches come in one standard length. With our smooth elastic cuff, they are meant to hit at the ankle or above. Our fabric does not stretch out, so be sure to order true to your actual measurements. Want them tight? Stay to your measured size. Want a bit of wiggle room? Size up for your perfect fit!
