A great birthday gift for your boyfriend who loves swimming could be:
1. A high-quality pair of swim goggles that will help him see clearly and keep water out of his eyes while he's swimming.
2. A swim tracker watch, which will allow him to track his progress and provide him with real-time data on his swim distance, stroke rate, laps, and more.
3. A waterproof Bluetooth speaker, so he can enjoy his favorite music or podcasts while swimming.
4. A custom-made swim cap or additional swimming gear to make his swimming experience more personalized and enjoyable.
5. A waterproof camera so he can take photos of his swimming adventures and share them with friends and family.
6. A subscription to a swimming magazine or an online streaming service where he can watch professional swimming competitions and learn more about the sport.
I hope these ideas help!
