Integrating hydrogels into textiles for firefighting personal protective clothing (PPC) could enhance thermoregulation and moisture management, providing firefighters with improved comfort and safety. Hydrogels are three-dimensional, hydrophilic polymer networks capable of holding substantial amounts of water. Their high water content and excellent thermal properties make them ideal for cooling applications. Therefore, this review focuses on the potential of hydrogel-infused textiles to improve firefighters\u2019 PPC by enhancing thermal comfort and moisture management. Specifically, hydrogel structures and engineered properties for enhanced performance are presented, including smart hydrogels and hydration customization mechanisms. Hydrogel integration into firefighting PPC for moisture management and improved thermoregulation is explored, including current and future market projections and state-of-the-art clinical trial findings. Overall, the future of hydrogel-integrated textiles for firefighting PPC is bright, with numerous advancements and trends poised to enhance the safety, comfort, and performance of protective gear.<\/jats:p>","DOI":"10.3390\/polym18020204","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T10:25:23Z","timestamp":1768213523000},"page":"204","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Review of Textile Hydrogel Integration in Firefighting Personal Protective Clothing"],"prefix":"10.3390","volume":"18","author":[{"given":"Sydney","family":"Tindall","sequence":"first","affiliation":[{"name":"FSU-FAMU College of Engineering, Florida State University, Tallahassee, FL 32306, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6216-3791","authenticated-orcid":false,"given":"Meredith","family":"McQuerry","sequence":"additional","affiliation":[{"name":"Therma NOLE Comfort Lab<sup>\u00ae<\/sup>, Jim Moran College of Entrepreneurship, Florida State University, Tallahassee, FL 32306, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josephine","family":"Bolaji","sequence":"additional","affiliation":[{"name":"Therma NOLE Comfort Lab<sup>\u00ae<\/sup>, Jim Moran College of Entrepreneurship, Florida State University, Tallahassee, FL 32306, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,12]]},"reference":[{"key":"ref_1","unstructured":"(2025, October 29).
