Q: What are your products made of?

 A: OS1st uses top-quality, high-performance, moisture-wicking materials with a silver-ion anti-microbial treatment. Materials include Lycra Spandex, micro-nylon, nano-bamboo charcoal, and Merino Wool treated with silver-ion for moisture-wicking and anti-microbial. The gel grip on the compression bracing sleeves is hypo-allergenic silicon. Please see product descriptions for more information.

 Q: How do I figure out my size?

A: All our products have a corresponding size chart that will help you choose the best size for you. We recommend using each individual size chart for each product. If you are between sizes, go with the bigger size.

Q: What’s different about our compression?  

A: Unlike some compression products, all OS1st products are 100% medical grade compression. We apply our compression with our patented Compression Zone Technology ® which targets specific joints and muscles so you can be active and pain-free.

Q: How do you fight odor? 

A: All OS1st products are treated with silver which is a natural way to fight odor.

Q: Do OS1st socks and braces wick moisture? 

A: Yes, all OS1st products use a high-performance fabric that wicks moisture away from the skin for a dry experience. 

Q: How do I wash my OS1st Socks

A: We recommend that you wash gentle on cold. Tumble dry on low heat. No bleach or fabric softener.

Q: How do I wash my OS1st Compression Sleeves? 

A: We recommend you hand wash with mild soap and air dry. No bleach or fabric softener.

Q: What size am I, since someone falls in two different size locations on the chart?

 A: If you are between two sizes choose the size up. If it is too loose, our 100% satisfaction guarantee will cover a size exchange!

Q: How long can I wear them? 

A: It all depends on how often you wear your product and what you do in them! A good rule of thumb is to check in at 6 months and make sure the compression is still working as it did when you bought it. We have a 100% satisfaction guarantee, so feel free to reach out to us at any point in the product life cycle.

Q: How much compression is in the product?

A: Our products use Compression Zone Technology® which uses varied levels of compression to target specific areas affecting the injury/pain. See individual product listings for compression range information.
