In a word, everything. Our revolutionary bras use an entirely new and patented technology designed to support over 80% of breast weight from underneath taking the strain off your back and shoulders. Each bra is lined in anti-microbial and wicking fabric cutting down on boob sweat to keep you fresh and dry all day. Trusst’s foundation in science means that we live and breathe weight distribution, stress points, and high-tech materials. No more poking wires, shoulder dents, back pain, or boob sweat.
