Re-waterproofing turnouts and breathability

[Iride]

It’s been a while since I’ve thought about this subject but, I sort of recall there being two camps in answering this question… If you re- waterproof a turn out blanket, can that affect the breathability of the blanket? I mean my knee-jerk reaction is to say no, because pretty much every blanket repair person I know also offers re-waterproofing and I would think that if that stopped the blankets from being breathable, they would either tell you that or they just wouldn’t do it.

In any case I would love to get your input on this! Thank you

It COULD, it depends on the product you’re using.

Using waterproofing made for equipment that needs to breathe - jackets, tents, shoes - is fine. I use the stuff in the big can with the neon orange top from Walmart.

Not all waterproofing is for stuff that is supposed to breathe, so don’t use those.

I use Nikwax Rug Proof and it does not affect breathability.
