Looking for boxers similar to Next A-front

I am a large man, and finding boxers is such a difficult task. Its that time if the year again where I go to order a new set of All White A-front Boxers from Next. But sadly, my size (XXL) is unavailable, and I need them urgently. Can someone give me recommendations for brands that are similar to Next?

Also, I know next have the Calvin Klein option, I don’t mind grabbing a pair or two for the meantime, but are they similar or not?

Thanks.
