• Ultra contour seamless construction follows the body's natural lines, with vertical panelling through the torso that creates a sculpted, second-skin fit without bulk.
• Nylon fabric sits close to the skin and moves with you - it holds its shape through high-intensity sessions and doesn't bag at the elbows or knees over time.
• Thumbhole cuffs keep the sleeves anchored during movement, preventing them from riding up mid-workout.
• Zip-through front allows you to layer over a sports bra at the start of a session and strip back as you warm up.
• Cropped-to-hip length sits neatly over leggings without bunching, making it practical for everything from treadmill runs to mat work.

The contour seaming is what sets this jacket apart from a standard zip-through - it runs front and back in a way that actually maps the torso rather than sitting flat. On the body, it feels structured but never restrictive, and the nylon keeps everything smooth rather than clinging unevenly. The mock crew neckline adds a layer of coverage without overheating, which makes it a solid choice for outdoor training in cooler months as well as air-conditioned gym floors. The model wears it zipped to the collar over matching seamless leggings - a clean, co-ordinated look that works equally well for a morning run or a reformer Pilates class. It transitions easily from the studio to a coffee stop afterwards without looking purely functional. If you already own pieces from the DSGN Studio seamless range, this jacket is the natural finishing layer.
