MLD SUPERLIGHT SOLO BIVY M Size

Purchased new from Mercari in 2025 and used once for tent camping. It was used with a ground sheet, so there are no tears or stains. It pairs very well with floorless tents and helps reduce the weight of your sleeping bag.
Personally, I think this is a great deal as a new one currently costs ￥51,700.
Please purchase with the understanding that this is a used item.

-The iconic model of water-repellent bivies, easy for anyone to use-

The SUPERLIGHT SOLO BIVY has been a long-selling product from MLD since its founding in 2004.
Along with TiGoat's Ptarmigan Bivy, it is an innovative item in the history of ultralight gear.
It is a very lightweight bivy with a mosquito net, weighing only 170g (actual measurement), and has a shape that allows it to be hung from above. It is a highly water-repellent bivy sack.
While not completely waterproof, it is significantly lighter than waterproof models and offers the following three advantages:

■ As a water-repellent bivy, it improves insulation by about 5°C during sleep, allowing you to use a warmer sleeping bag, and the bathtub-style floor eliminates the need for a ground sheet, contributing to overall weight reduction.
■ When used with a floorless shelter or for cowboy camping, it prevents insects such as mosquitoes and ticks from entering, and the mesh head prevents condensation from breathing.
■ There is no worry of your sleeping bag getting wet from condensation, and on clear days, you can sleep while enjoying nature without setting up a tarp or floorless shelter.
