Not only did the pro heroes noticed, but also the UA students also noticed that their hero costumes are way different and have a lot of upgrades and have more proofs like bullet-proof, fire-proof, protects them from hot or cold weathers, better support items, and protect their physical-health bodies from any quirk injuries. Especially Momo Yaoyorozu and Toru Hagakure got hero costumes improvements too be more supportive and helpful. The heroes are really impressed with their costumes upgrades and it's more helpful and comfortable to fight and train especially the pro heroes and All Might.
