Dyneema repair

“Rip”…? Tiny? Gaping? Pics?

Cuben tape with the edges backed up with Aquaseal wound be a good-as-new repair.

That looks like a reasonably low-stress spot. After the DCF patch and edge seal repair, just  thread the pole carefully. Zpacks sells DCF repair strips in 54” lengths.

Is the sleeve made of DCF? probably not?

Sleeves made of DCF should not be reasonable because it has no stretch.

From the pic, it looks like normal fabric. Then the way to repair is more limited.

Whoah! what tent is that?

Concur on the DCF tape

The tent looks like silnylon.  Would not the sleeve also be silnylon? Cannot really tell from the photo. If it has a sewn seam that would rule out DCF, yes?

If the sleeve is DCF, like others above, I have used the zpacks DCF tape for all kinds of repairs on DCF. Works great.

-You’ve got me drooling

So I’ve had great success with DCF tape on many different types of fabric. Goretex, Tyvek, different types of nylons, polyesters, DCF. It always holds. In my experience
