adidas Fs Ob - Black - UK 4

The open-back design offers enhanced freedom of movement for the shoulders and arms, reducing drag and allowing for a more natural swimming stroke. It is preferred by many competitive swimmers and those focused on performance training.

Refer to the adidas official sizing chart, typically available on the product page or brand website. Measure your bust, waist, and hip, and compare these measurements to the chart. It's often recommended to size up if you are between sizes for comfort.

While the suit is durable, its performance-oriented, open-back design is best suited for swimming laps and competitive training. For fitness classes, a suit with more coverage and support might be preferable.

With proper care and rinsing after each use, the adidas Fs Ob Ld99 is designed for durability. It should maintain its shape and performance for a significant period, though lifespan can vary based on frequency of use and water conditions.

It is primarily designed for chlorinated pools. While it can be used in the ocean, it is crucial to rinse it thoroughly with fresh water immediately after use to remove salt and sand, which can degrade the fabric over time.

Specific fabric composition details can usually be found on the product's care label or the manufacturer's website. Typically, performance swimsuits use a blend of nylon and elastane (spandex) for stretch, durability, and chlorine resistance.

Ensure you have selected the correct size by consulting the adidas sizing chart. If between sizes, consider sizing up for a more relaxed fit.

This may be due to improper care or prolonged exposure to harsh chemicals. Always rinse thoroughly after use and avoid high concentrations of chlorine or oils. Follow the care instructions meticulously.

The open-back design prioritizes freedom of movement. Ensure the straps are correctly positioned on your shoulders and adjust if possible. If discomfort persists, this style may not be suitable for your body type.
