DDD+ bra that actually survives extreme heat conditions without creating a cleavage swamp? This is the only bra I have found that fulfills that. This is my go-to travel bra for 6+ hour flights, racerback tank tops and Phoenix's 115F summers.

This bra is like a unicorn. Large busted, small banded women in hot climates take notice and get fitted for this bra. Runs true to Natori sizing, but the flexible, soft and elastic fabric may not provide sufficient support for very pendulous or top heavy breasts so try it before you buy it.
