The Natcool PJs are excellent - barely-there fabric, comfortable shape. The most comfortably pyjamas I’ve seen, anywhere.
However the UK price is VERY high and I do think Dagsmejan needs to keep an eye on their pricing model if they are going to grow well. Delivery to the UK is also quite slow (3-7 days; compare with Meyer trousers in Germany who have 1-2 days delivery reliably) and at the UK end they use Evri, which has the worse reputation of any courier company — not what we would expect for a top-priced brand.
