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.
All OS1st 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.
Unlike some compression products, all OS1st products are 100% medical grade compression. OS1st applies compression with their patented Compression Zone Technology ® which targets specific joints and muscles so you can be active and pain-free.
All OS1st products are treated with silver which is a natural way to fight odor.
Yes, all OS1st products use a high-performance fabric that wicks moisture away from the skin for a dry experience.
We recommend that you wash gentle on cold. Tumble dry on low heat. No bleach or fabric softener.
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.
OS1st 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.
