Patch outer fabric of phantom techs

My crampons straps wore a hole through the outer fabric of both my phantom techs as well as the next layer below. Now snow can get inside. 

I'm thinking of using some aquaseal SR (or FD?) and trying to affix... Various materials over the hole. Maybe a piece of an old hardshell, soft shell, or Bike tube?

Has anyone had success fixing this? What glue and patch did you use?

It doesn't really need to be 100% waterproof against immersion , just keep snow out most of the time 

You should try zip tape. It’s a flashing tape. There is a regular one and a stretchy one that made for flashing around doors and windows. I find the stretchy one works best for soft shell type materials. If you take the time to trim the corners off your patch it’s surprisingly good. I have some on a pair of softshell pants that has held for a season. I have some of the regular tape on a hardshell pants for three seasons. The only problem is it’s crazy expensive. If you know any carpenters or contractors they may have some you can steal a few pieces from. If not I could mail you some of the stretchy stuff if you want. It comes with a backing you peel off so it could go in an envelope. 

I had the same issue, and tried aquaseal on its own on a pair of phantom techs, with limited success. My next attempt will be to apply aquaseal to a 'patch' piece of cordura, then slide that in to place on the inside of the gaiter.

Haven't seen anything like this... Weird your crampon buckles are riding up over the rubber.

That said, I would try and get tenacious tape down in from the inside and then a layer on the outside... The hardest part is going to be getting it down low to the seam on the inside and/or removing the backing material...

Or in the off season send them to scarpa or a scarpa cobbler for repair?

I have also tried repairing an issue like this with different types of goop and they all made a bigger mess than did anything helpful. Scrap some flashing tape from a construction friend! It’s impressively sticky

I used Wigluv a Swiss flashing tape made by Siga to fix a much smaller hole in my phantom techs and so far it’s been holding up well. Colin Haley certainly uses loads of the stuff to patch holes in his pants and jackets. Not sure how it would work with such a big hole but maybe a layer on the inside and one in the outside would hold up. IDK just my 2cents

 managed to grab 2 pieces of flashing tape from a coworker. 

3M 8067 seems to be staying on ok, it's only been 2 days so far though. 

DuPont flashing tape is falling off pretty immediately. 

In order to prevent further abrasion, I removed the crampon straps and used a ski leash to attach the crampon to the boot zipper pull. This seems to be working ok so far. It does not cause the zipper to unzip.

Whenever you're patching stuff, its best to cut the corners to rounded edges.

And clean the area with rubbing alcohol beforehand.

Wash the area with alcohol, cut a square of bike inner tube to size, round the corners. Try to cut the shape to adapt to the flex area. Sand the surface and wash with alcohol. Glue on with aquaseal. Cover the patch with cling wrap and clamp for 24 hrs in a warm place.
