SLEEPING BAY GROUNDSHEET ($49)
The Single Best Upgrade for Your Sleeping Bay
The Atacama's bathtub floor is waterproof. But without a groundsheet underneath, cold ground and moisture still transfer through — and that's where condensation starts, from below the floor, not above it.
This custom-fit groundsheet sits beneath the sleeping bay, between the tent floor and the ground. It breaks the cold transfer, dramatically reduces condensation inside the sleeping area, and protects the bathtub floor from abrasion on rough or rocky surfaces.
If you're using cots, it matters even more. Cot legs sit directly on the floor. Over time, on harder terrain, that contact wears through. This groundsheet takes that punishment instead.
Why It's Worth $49
— Eliminates direct ground-to-floor contact — the primary source of condensation in the sleeping bay
— Protects the bathtub floor from gravel, rock, and rough surfaces
— Essential if you're using cots — prevents leg abrasion on the floor over time
— Custom-fit to the Atacama sleeping bay — no excess material, no pooling edges
— Clearly marked SLEEP so there's no confusion with the garage groundsheet
— Lightweight 6oz material — adds almost nothing to pack weight
Most condensation issues in tents come from the ground up. This is the fix.

Pro tip
Always tuck any excess material under the tent floor. Exposed edges act as water channels. Tucked edges stay dry.

Worthwhile addition
The groundsheet does not come with the tent as ordered. It's additional, but the first time we used it, it saved the base of our tent. We were in very rocky territory and we managed to get holes in the groundsheet. You might ask, why pay $50 for something a $10 sheet of plastic or a tarp may do the same. Just try putting either of those down in a gale and getting the tent on top of it! This groundsheet clips to the underside of the sleep area into clips presewn onto the tent. It all rolls up together so no problems in getting it in the right place. While your at it, but the garage ground sheet, it clips in too, nice to be able to take of your boots and not walk in damp or wet grasses of in dinoflagellates any kind.

Glad I purchased it
Installed easily and fit perfect. Leaving it on, when breaking down the tent, makes it ever easier, the next time, you go camping

Good protection
The sleeping groundsheet fits nicely into existing clips on the tent, it will be good at making the inner tent last longer. I have left mine attached to the tent so when I set up the sleeping groundsheet is already there.
