Raincover Ultra™ offers strength and durability, is light in weight and easy to handle field cover.



As the company who introduced lightweight field raincovers over 30 years ago, Covermaster continues to lead the industry. Our ongoing Research and Development, coupled with our experience and customer feedback, has led to the latest technology in lightweight Raincover design.

Raincover UltraTM, we have created the industry’s strongest core raincover, which is critical when removing hundreds of pounds of water from the cover’s surface. We then reconfigured the weave count of the core, resulting in a more stable base, as well as creating a 100% sunblock, to keep the turf cooler. In addition, the core tapes are pre-elongated, which stretches each strand of the core prior to use on your field, resulting in a highly stabilized cover, which is more durable, and results in less stress on the raincover’s surface coating. Then, to keep the turf cooler and drier, we utilized our exclusive Shield-Tek™ coating technology.

The Raincover Ultra’s surface is designed with less friction in mind, to resist dirt accumulation better than other covers, as well as making it easier to remove snow and ice. All of this was accomplished without sacrificing weight. At over 200 pounds lighter than other available covers, Raincover UltraTM is not only the strongest cover of its kind, it is also easier to handle and saves time and labor costs.
