What sports bras can act as a substitute binder?

Hi! So im personally not trans myself however my partner recently came out to me as trans masc and I need some advice. He came out to me around a month ago, as im not really someone to care about gender I wasn’t phased however I identify as a woman so im not properly able to relate with alot of his problems. Recently he has been having issues with his chest as hes on the larger spectrum, due to his living situation hes stuck with his parents and can’t exactly buy a binder so we’ve been looking at sports bras instead. Does anyone know a sports bra that can act as with good compression? Preferably one thats more comfortable (I know with compression thats hard but it doesn’t hurt to ask) I really want him to be more comfortable in his own skin so im trying everything I can. Thank you!!!
