The tub-style groundsheet is virtually indestructible and allows camping on any surface. Even if your tent sits in 10 cm of water for months on end, you and your gear will stay perfectly dry. The groundsheet is attached to the tent with a heavy-duty zipper so that water and vermin have no chance.

Wood-Burning Stove: 

• Yes – all of our tents can be equipped with a stove.
  Unlike some models, this series does not come with a pre-installed stove vent, giving you the freedom to choose the stove type and placement that best suits your needs. Our CanvasCamp Stove Exits are compatible with any stove and can be installed anywhere in the tent in just about 10 minutes.

Note: We do not recommend using a wood-burning stove in a Sibley 300. The tent’s compact size makes it difficult to use a stove safely and comfortably.
