Starts out light and stays that way

Your exercise should start when you get in the water, not getting the cover off your spa. DuraCore covers have a patent-pending internal insulation pack with multiple vapor barriers and nothing to absorb water, so your cover is guaranteed to stay light year after year.


A lifetime fabric covering

Your swim spa is a big investment.  Why shouldn't the fabric covering on your cover last as long as your spa?  We use the most advanced marine fabric covering of any spa cover. Made from solution-dyed polyester fibers, it has a lifetime warranty against cracking.  And who wants to crawl around applying UV protectant?  With DuraCore, the UV protection is built-in for the life of the cover.

The best spa cover for the planet


Standard vinyl and foam spa covers waste a lot of energy over their short lives, then head to landfills where they sit for hundreds of years.  Modern covers last far longer, are made of 90% recyclable and reusable materials, and save literally tons of carbon over their lifetime.  

Plus Modern offers the only solar heating spa cover on the market, our SunCatcher spa cover, which offsets up to 80% of electric heating, saving up to 20 tons of greenhouse gas emissions over its life.


SunCatcher's solar heating technology was awarded

First Place for Best Green Product at the International Pool and Spa Expo.
