The fabric selection and size range are the main features, and both are chosen to support active use.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe main fabric composition is 100% polyester fibre. This material is widely used in sportswear because it dries quickly, resists wrinkles, and holds colour well through repeated washing. The construction is a simple sleeveless cut, which allows maximum freedom of movement for your shoulders and arms during exercise like weightlifting or running.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe vest comes in five sizes: S, M, L, XL, and XXL. Each size has a specific bust measurement ranging from 80 cm (size S) to 96 cm (size XXL) and a length from 63 cm to 71 cm. Because these are Asian sizes, they are designed for a slimmer fit. If your measurements fall between two sizes, the advice is to choose the larger size. The product also recommends contacting customer service if you are unsure about sizing.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Men's polyester fibre sports vest sleeveless activewear for gym running workout\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US06\/2750\/2025-10-24\/original-image\/1743170399182.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis vest is designed for active situations where a lightweight, breathable top is needed.

The polyester fibre helps wick moisture away from the skin during exercise, keeping you drier than cotton would. The sleeveless design also helps with airflow, which can be helpful during intense sessions.\u003c\/p\u003e\u003ch3\u003eEveryday Casual Use\u003c\/h3\u003e\u003cp\u003eBeyond sports, this vest can be worn as a casual layering piece under an open shirt or jacket.
