Reclaim Your Command
The Stratum Core V1 isn't just an undershirt. It's an architectural foundation for the modern man — instant abdominal compression, structural lumbar support, and a shape you can wear under anything.
Midsection Sculpting
High-density elastic panels flatten the stomach without restricting your breathing, giving a cleaner silhouette under shirts and suits.
Postural Correction
X-patterned back tension bands pull the shoulders back, aligning the spine and easing lower back pain through long days at the desk.
Ultra-Thin Weave
Laser-cut edges and moisture-wicking fabric keep the vest completely invisible, even under a light cotton dress shirt.

Technical Specifications & FAQ
How do I choose my size?+
Our vests are built for high compression. If you are between sizes, size up for comfortable all-day wear, or stay true to size for maximum sculpting.
Will it show under my shirt?+
No. The weave is ultra-thin with laser-cut edges, so there are no visible seams or lines even under light cotton or linen shirts.
Is it machine washable?+
Yes. Wash on a cold cycle (30°C) and air dry to keep the compression fibres at full strength.
