This product originally found popularity under the name Tufbell, but is now produced using the same materials and processes under the name DIO-Betalon. PVA (polyvinyl acohol) is a polymer with a unique hygroscopic characteristic which draws moisture to it; this layer of moisture will freeze when temperatures drop, forming an igloo-like protective shield that maintains the temperature beneath the row cover.

While DIO-Betalon may be laid on hoops or frames as other covers, it is lightweight enough to be floated directly on top of most crops. The PVA film allows air and light through during the day, and its even possible to water right through the material. The material is tough and very durable. It's among the most durable row covers on the market, and if it is damaged it can actually be sewn with nylon thread. 

We recommend using Tufbell Clips to anchor our DIO-Betalon products.
