Hiking on the coast makes one battle wind and/or humidity. One morning on the coast, I woke up to slight condensation on inside floor due to temperature differences between the ground and humid air inside the tent. I thought that best way to reduce this is to start using a groundsheet. Now having an ultralight DCF tent with a groundsheet sounds a bit paradoxical, but I’m reducing condensation is worth it in my books. Having better water resistance and cleaner tent floor are also nice to haves.

I never worked on DCF before, so this would be my first foray into Dyneema, and it was a bit of a learning curve.

I ordered all the materials from Dutchware: 1oz black DCF, 1/2” CT-PSA tape and 1” CT-PSA tape. Webbing I already had from before.

I cleared out the living room floor and spread out the DCF and cut it to a rectangle.

I then used the 1/2” CT-PSA (double-sided) tape and taped the edges.

I then proceeded to make the patches for the corners. I cut them to shape, then made some webbing loops and sewed them onto the patches with tack stitches. I copied the tack configuration from the official Durston groundsheet.

I taped the corner patches and the pole loop patches on their locations. I used a roller to press the layers together and to reduce wrinkles.

I used a roller cutter, which got blunt pretty quickly. Still found it the best way to cut the long runs. I then cut it to a parallelogram based on Dan’s picture (I added the cms for my own use). I added 1/2” seam allowance all around.

I then folded the seam allowance and taped it onto the body.

I added double-sided CT-PSA on the back of the loop patches.

Here’s the finished product. Durston’s official X-Mid Pro 2 groundsheet weighs 135g. This one comes in at 101g (3.6oz) without any cordage.
