I like their thermals and found them pretty good in terms of heat (well only tried their top, only now bought the bottom). Probably as good as the EDZ ones I have. In terms of comfort they are very much more a tight fit, they feel a bit like wearing a jumper that’s two sizes too small but they stretch so much that’s they aren’t small.
I find clothes comfort increases after a couple of wears/washes, the fabric tends to stretch/shrink into a more comfortable fit
Time will tell. I still have the old Tesco thermals as back up
I bought Lidl thermals a few years ago and they’ve been great, starting to wear through now so got some more, they seem pretty similar so fingers crossed. The socks were also pretty good.
