Definitely way out of my price range especially taking delivery and import fees to uk into account.
They are an interesting design though for a diaper cover, might have to look into replicating it and sew something similar to give it a try. would need to decent all round picrues though to see how it is put together but I imagine it's not that hard.
I've been wearing the threaded armor briefs pretty much all day since they arrive in the first week of this month, out to work and around the house and have been quite impressed with them, just finished testing some alternative inserts I made (same design and size different fabric type) to see if they will be any better and if I can make my own (since threaded armor are not cheap either).
The briefs are actually really good for day wear, I simply would not trust them over night though. I have been wearing boxers over the top which I normally don't do but wearing all day I noticed a lot of chaffing with my trousers on my thighs and the boxers stopped that, so I wonder if something like these Protecbriefs would give the same chaffing protection boxers do with added leak protection, especially for overnight.
An idea to toy with as I practise more with the serger I guess.
