Hello! According to your measurements of 176 cm tall and 105 kg, the recommended size is **XL**, depending on your weight. However, considering your weight-height ratio, if you prefer a looser and more comfortable fit, you can consider the **XXL** size, which is one size larger. This will give you maximum comfort and extra range of motion. Thanks to the premium lycra fabric structure of the Nova Series, both sizes will offer you flexibility and comfort. It would also be helpful for you to decide by examining the size chart in the product images. Thank you for your interest in Class Uniform! 🌿
