The MT Vivi is made from soft, waterproof, and breathable Tyvek fabric.

It can be used not only as a sleeping bag cover but also as a stand-alone tent.

Large zipper for easy access.

The zipper has a double structure, allowing you to open and close the Tyvek and mesh separately.

The mesh keeps out insects while still allowing enough ventilation to let in fresh air, preventing condensation inside the bivy on humid nights.

To allow for active use as a freestanding tent, the tent has two bungee cords at the top, which can be attached to standing trees or trekking poles to expand the space inside the bivy tent.

The bungee cords allow you to lie down in your bivy tent and still have space to use your smartphone or read a book.

Dyneema fabric is used to reinforce areas that are most likely to be under stress, such as the four bottom corners of the peg-down points and the two vertices where the bungee cords are attached.

This tent can be used as a freestanding tent or in combination with a floorless shelter.
