The covers we use are a much thicker alternative than those used in Mongolia. The material is a 450gsm material specially acquired from China to perform better in the UK. It has a rubberised internal layer which is a fantastic barrier, sewn into that is our green outer canvas. The seams have been sealed to ensure a long life.
We recommend helping the covers with a spray of fabsil waterproofer when setting up at the start of the season.
