EXTRA SAFE DUREX condoms. Durex Extra Safe variants are essentially the same as the standard versions, but with added thickness and extra lubricant to boost smoothness during intimate moments, helping you get the most from the experience. They also come with a more pleasant scent to enhance your time with your partner. Pick the fit that suits you: we’re all different, but the right condom should always feel comfortable and secure. That’s why Durex offers a condom designed for you. Every Durex condom undergoes 100% electronic testing and passes five quality checks, giving you the confidence to enjoy sex fully every time. They are also dermatologically tested.
