Steadfast™ – Outside-Wire High Impact Sports Bra for Fuller Busts + 50% OFF｜ Underwear & Lingerie

Your Workout Deserves a Bra That Never Flinches
You know the feeling — mid-run, mid-burpee, mid-jump — and suddenly you're adjusting, tugging, wincing at the wire digging into your ribs. Every rep becomes a negotiation between your body and a bra that won't cooperate.
The truth is, most underwire sports bras were designed with the wire pressing directly against your skin — and for fuller busts, that's a recipe for pain. Steadfast™ was engineered the opposite way.

The wire sits on the outside of the cup. A soft fabric barrier rests between the wire and your skin — so you get full structured lift and separation with zero digging, zero poking, zero shifting.
That means you stop thinking about your bra entirely — and start thinking only about your next rep, your next mile, your next personal best.

FAQ

Can I feel the outside wire through the fabric?No — the wire is integrated into the exterior structure of the cup and covered by smooth fabric on both sides. You won't feel it against your skin or see it through clothing. What you will feel is structured lift without any digging or poking.

How do I find the right size?Measure your underbust in inches and match it to our sizing chart. The bra is available in band sizes 28-48 and cup sizes B through I. If you're between sizes, we recommend sizing up for the most comfortable fit.
