Frequently Asked Questions

Everything you need to know about your 4Endurance order

How do I determine the right size for my performance gear?

Each product page features a detailed 'Size Guide' with specific measurements. We recommend measuring your chest and waist to ensure the best aerodynamic fit for your training.

What is your return policy for apparel?

We offer a 30-day return window for all unworn items with original tags attached. For hygiene reasons, undergarments and used socks cannot be returned unless there is a manufacturing defect.

How long does shipping take?

Standard shipping typically takes 3-5 business days. We also offer express shipping options at checkout if you need your gear ready for an upcoming race weekend.

Are 4Endurance fabrics moisture-wicking?

Yes, all our performance apparel is engineered with advanced synthetic fibers designed to wick sweat away from the body and dry rapidly during high-intensity workouts.

Do you ship internationally?

We currently ship to over 50 countries worldwide. International shipping rates and delivery times are calculated at checkout based on your specific location.

How should I wash my technical clothing?

To preserve the elasticity and technical properties of the fabric, we recommend machine washing in cold water on a gentle cycle and hanging to dry. Avoid using fabric softeners or bleach.
