Men's Square Leg / Trunks Buying Guide
Q: What is the difference between Trunks/Square Legs, briefs and knee-length swimming trunks?
A: SWIM BOXER, The length of the trouser leg is about the top of the thigh (5-10cm), between swimming briefs and knee-length swimming trunks. It is slim-fitting but has more comprehensive coverage. It is a style that balances professional training with daily swimming. Briefs have the least resistance but are highly exposed; jammers cover above the knees and are mostly used in competitions. The flat-footed version is most popular among Asian swimmers, offering both comfort and professionalism.
Q: What occasions are square swimming trunks suitable for?
A: Boxer swim trunks are the first choice for multiple uses: perfect for daily pool training, swimming lessons, fitness swimming, hotel pools, and indoor competitions. Compared with the triangle version, it will not be overly exposed, and it is more convenient to put on and take off than the knee-length version. For swimmers who have just switched from casual board shorts to professional training, flat-foot styles are the best transitional choice.
Q: How should I choose the material of my flat swimming trunks?
A. For daily training, it is recommended to choose PBT polyester fiber material, and has a service life of up to 1-2 years. If you are pursuing the ultimate fit and low resistance, you can choose Lycra/nylon blend, but its chlorine resistance is weak, so it is recommended to be used only for competitions or short-term use. Be sure to rinse away chlorine and sweat salts with clean water after each swim.
