My NRS Triton Inversion drysuit has totally lost its waterproofness after 4 winter seasons. I dried it out and immersed it in the laundry sink to make sure it wasn't just sweat, and the water soaks right through. I would expect the Triton laminate to be at least somewhat waterproof even if the DWR wears off, but the fabric has no water repellency at all. Has anyone had a similar experience with the Triton fabric?
I read the earlier thread about restoring the DWR and tried the 303 Fabric Guard, with zero results. However, the bottle I have is about 8 years old, so it's probably past its effective shelf life. Does anyone have experience renewing the DWR specifically on Triton fabric, and can you recommend the best product to use?
