Ripped my trousers and tape has come away in my jacket, want to get ut sealed instead of retaped if poss.
Seam sealer, the tube of stuff you use with tents will work.
+1 seam sealer
You're gonna have to do something with the tear on the trousers first though, stitch/glue/patch etc, unless it's on a seam.
McNett tenacious tape is good for patching holes and tears.
LSR @ Preston is my go to place for any outdoor clothing repairs.
Alpkit repair any brand of outdoor clothing, could try them.
Duct tape
Try Stormsure - https://www.stormsure.com/ - I have used their products to repair waders, tents and clothing. Good stuff
I’d send it to alpkit
I used a tent style glue from Ho outdoors for the seams that came away on my waterproof trousers,it does a job but I reckon retaping would be ideal
