Fabrics that are exhibit water repellency, abrasion resistance, and optionally flame resistance are described herein. The fabrics include a plurality of fibers (such as flame resistant fibers) and a finish that imparts water repellency and abrasion resistance to the fibers. The fabrics are free or substantially free from alkylfluoropolymers. Also described herein are garments including the fabrics. 1. A water repellant and flame resistant fabric , comprising:a plurality of spun yarns comprising a plurality of flame resistant fibers; anda finish that imparts water repellency and abrasion resistance to the fabric, the finish comprising: (a) a water repellent agent selected from the group consisting of a hydrocarbon-based polymer, a silicone-based polymer, a urethane-based polymer, and an acrylic-based polymer and (b) a polymeric abrasion resistance aid,wherein the fabric, before laundering and after being laundered five times in accordance with AATCC test method 135 (2018), hasan abrasion resistance of at least about 500 cycles before a first thread break when tested in accordance with ASTM test method D3884 (2017) (H-18, 500 g on each wheel) and a water absorption of less than or equal to 15.0% as determined by NFPA 1971, 8.26 (2018).2. The water repellant and flame resistant fabric of claim 1 , wherein the finish is substantially free from alkylfluoropolymers.3. The water repellant and flame resistant fabric of claim 1 , wherein the water repellent agent comprises a hydrocarbon-based polymer.4. The water repellant and flame resistant fabric of claim 1 , wherein the water repellant agent comprises a silicone-based polymer.5. The water repellant and flame resistant fabric of claim 1 , wherein the water repellant agent comprises a urethane-based polymer or an acrylic-based polymer.6. The water repellant and flame resistant fabric of claim 1 , wherein the polymeric abrasion resistance aid comprises an acrylic polymer.7. The water repellant and flame resistant fabric of ...
