Frequently Asked Questions
Everything you need to know for your best night's sleep.
How do I find the right fit for my Manta Sleep mask?
All Manta masks feature adjustable eye cups and a modular head strap. You can reposition the cups anywhere along the strap to ensure a perfect, 100% blackout seal tailored to your unique face shape.
What is your 60-day money-back guarantee?
We want you to love your sleep. If you're not satisfied with your purchase within 60 days of delivery, you can return it for a full refund. We even cover return shipping for our customers in the USA.
How should I wash and care for my Manta products?
To maintain the quality of the materials, we recommend machine washing your mask in the provided laundry bag using cold water. Always air dry; do not put your mask in the dryer as high heat can damage the foam and elastic.
How long does shipping take?
Standard shipping within the USA typically takes 3-7 business days. International shipping times vary by location but generally range from 7-21 business days depending on the customs process.
Are Manta Sleep masks suitable for side sleepers?
Yes! Our masks are designed with tapered sides and soft, flexible materials specifically to remain comfortable and stay in place even if you sleep on your side.
Do you offer a warranty on your products?
We stand by our quality. All Manta Sleep products come with a 6-month warranty against manufacturing defects. If your mask has a functional issue, we will replace it free of charge.
