If the coat is bulky enough you would be able to wear that underneath, Bani, which is quite handy, also, something I'd want in a rain coat, the ability to wear a small bag underneath instead of leaving that to soak or some sort of compartment for it.
I've always had the unique ability not to get out of rain trousers without wetting myself (not an incontinence issue, I stress). They really are only useful if you're going from A to B and you can leave them to dry somewhere and drip all over the floor
, otherwise just useless.
I hadn't checked the English on Agu. It doesn't surprise me, I would say the Dutch are actually pretty poor at English but it's just more people on average have a good basic grasp of it but anything beyond that is really crap. When I was at uni they started making the transition from Dutch to English as the main language on a lot of courses to appeal to more international students, it was startling to see how little English most students and professors possessed. Understanding is not such an issue, speaking will get them pretty far but written English is just sub par. It doesn't really help that everyone keeps telling the Dutch they're so good at English as they tend to believe it and think anyone can translate it for business purposes without running a critical eye over it.
The company I interned for was updating their website and wanted it available in English too and it was so poor I had to intervene and ended up doing the translation from scratch. They'd actually paid someone (friend of a friend, as these things seem to go) for it, it was little better than a Google translate. There's also a thriving translation business for academics to get their work translated to English, it seems like such a basic skill at that level to me but many don't have it. I think a large issue is that English and Dutch have a lot of similarities/words but the grammar is completely different (Dutch grammar is not that different from Swedish actually) so it just comes across as really clunky when you see it written down.
I think my mistake has been in looking for an all in one thing, it seems many brands just sell them seperately Flo and then decided to make no mention of them anywhere, not even a suggested users who bought X also bought lining Y
