With a PVC base, this Campmor roll-up bivi is all you need for a night under the stars. The top is ripstop canvas, with a side zip and hooded section, and it includes a mattress. The bivi rolls up for storage and transport and has two straps to secure it when rolled up.
LRO's Calum says: 'Also protects against bear attacks.'*
*May not actually protect against bear attacks.
