Do Ekodomes come with a fabric shell?

Ekodomes are hard-panel geodesic dome kits.

No, Ekodomes do not come with a fabric shell, cover, or membrane. 

Ekodomes are covered with hard shell panels that will prevent forced entry by wild animals or intruders. You can't slash an Ekodome with a utility knife.

Ekodome offers 4 hard-panel materials: High-pressure laminate (HPL) compact laminate, Polycarbonate, Double-pane glass, and HPL SIP.
