Do you mean the color? They are a darker grey, I didn't see any khaki ones? I'm undecided about keeping them as well, mine are too long and I don't really like the fit. They also go baggy in the knees when you wear them for a while and I hate that.
I meant those... they come in black and khaki, but the khaki ones look rather like grey in the catalogue. but apart from the colour, they still look really different, not really like treggins, but rather like "normal", not that tight pants.

I made the mistake not to send them back, but returned them in the store, which turned out to be a major adventure, not only for me, but also for 3 (!!!) sales assistents. Because on that listing, you get with the delivery, they had made some mess by listing the correct article's name and price, but interchanged the reference numbers. So my 30 € "treggins" had the correct price, but a 5 € basic top's reference no. And it really costed some effort to persuade the women, that that article I was returning, was not a 5 € top, but 30 € treggins.
but what totally p**** me off, was the behaviour of some stupid teenage girl, who was totally unfriendly, insisting, whether I "hadn't checked the prices", or if I would "just take the stuff, without caring what it costs".... I tried to point out, that names and prices were matching, and that I just didnt compare reference nos on the articles tags with those on the listing (who does that???). it took some time, till the young lady's intellect managed to make use of this information.
last joke: she really did ask me whether I didnt find it strange, that this top was ONLY 5 €. I was quite close to telling her that about half of her stores range of products was only 5 €...
arrghhhh seriously... I know this is off-topic, but how comes noone had told the little one, that a sales assistent has to treat customers in a friendly way. And in a specially friendly way, if it was the store, not the customer, who had caused the mess...
another thing (and on-topic for a change

I realised, that hm almost only makes their basics in pastel colours. I usually just order basics and "1 season accessoires", and almost all I got this time, is black, white or grey. I've got dark hair and a fair skin, and all those light blue, light green and pink stuff doesnt suit me at all. Why dont they have a single simple tank in red or "deep" green?
