Soutiens-gorge croisés en X

The cross-strap structure distributes pressure across multiple points on the back and shoulders rather than concentrating it on two straight straps. This means the bra stays in place more consistently during movement — the straps are less likely to slip off the shoulder, and the multi-point fit creates a closer, more secure wrap around the chest.

For low-to-medium impact activities like yoga, Pilates, and strength training, this translates to noticeably less shifting and bounce compared to a basic straight-strap design. Saltum criss cross back also opens up more shoulder blade mobility, which makes a real difference during upper body exercises — push movements, pull-downs, or overhead work — where a traditional bra strap can dig in or restrict the shoulder's range of motion.

Saltum's criss cross bras are made with high-stretch fabric that conforms closely to the body's shape, which helps the back straps maintain their position throughout a session. The cross structure naturally anchors the straps relative to each other, which reduces independent movement and keeps the fit stable even during dynamic exercises. If you're between sizes, sizing down typically gives a more secure fit for active use.

A well-fitting sports bra should feel snug but not restrictive — you should be able to take a full breath comfortably, but the band shouldn't shift or ride up during movement. For criss cross styles specifically, the back straps should lie flat against the skin without digging in or gapping away from the body. If the straps are twisting or sliding off the shoulders during activity, the band size is likely too large.

It works well as a standalone top, and that's increasingly how most people style it. The back design — with its defined cross-strap lines and open structure — is visually strong enough to carry an outfit on its own, which is why criss cross bras have become a go-to piece for gym wear that doubles as casual or athleisure dressing.

Paired with high-waisted leggings or biker shorts, it reads as a complete, intentional outfit rather than just underwear. For extra coverage or layering, it sits naturally under an oversized jacket, windbreaker, or lightweight sun jacket — the back detail is still visible and adds interest to the overall look.
