I've got a Sea-To-Summit eVent compression bag - size medium. Fits a 20 degree no problem.
It has some marks (mostly soot/dirt marks from being packed next to my cook pot) and a 1 inch tear that's been repaired with wader repair glue.
If interested I'll send you pictures. https://seatosummitusa.com/products/event-compression-dry-sack?variant=7896126914588
Haha thank you. I take the weight and bulk penalty because they can be stored compressed and soaked completely through and still work (7 years with the same Wiggys Ultima Thule) but man 5.5 lbs and huge haha
