Nice thermal beanie

Needed a new beanie for my walks. Found British Thermals and got one of their thermal beanies. It's comfy and keeps my head warm. Nothing fancy, but it does the job. Shipping was alright, got it within a week. Good experience overall.

Good value thermal set

I was looking for some warm thermals for winter and found British Thermals. I bought a men's thermal underwear set during their winter sale. The discount was pretty good, saved about 15%, which made it feel like a smart purchase. The set feels well-made for the price I paid, definitely worth it for staying warm.

Reliable warmth, consistent quality

I've ordered from British Thermals a few times now, mainly for their kids' thermal underwear and some wool mix socks for myself. This latest purchase, a women's thermal vest, was just as good as my previous ones. The quality is always consistent, and they hold up well to washing, which is important for kids' clothes. My first order was years ago, and I keep coming back because I know what to expect. No surprises, just solid, warm gear every time. Delivery is usually pretty quick too, this one arrived in about a week.

How's the sizing run for these? I'm usually an L but sometimes thermals can be super tight or weirdly baggy. Should I size up or down for the men's long johns?

L Laura P. 1 month ago

I found them pretty true to size for men's stuff. I wear an M in most brands and their M fits me well, snug but not restrictive.

T Tom Marsh 1 month ago

Hmm, I went with my usual size for a women's top and it was a good fit. I think they have a size guide if you dig around a bit on their site, might be worth checking your measurements against that.

Anyone know if they offer a first order discount? About to place a pretty big order for the whole family, would be nice to save a bit.

M Mia Hughes 1 month ago

I think so! I got a little pop-up for like 10% off when I first visited their site. Maybe try opening it in incognito mode if you don't see it?

M Mike 1 month ago

Yeah, there usually is one for signing up for their newsletter. Keep an eye out for that. They also do multi-buy discounts sometimes which are applied automatically.

Hey, thinking of getting some thermals for my trip to Alaska next winter. Are these actually made in the UK or is it just a name?

K Kevin F. 2 months ago

Yeah, they're legit. I remember reading somewhere on their site that they've been making stuff in the UK since the 80s. Good quality too.

M Mia 1 month ago

Can confirm, pretty sure they boast about being UK-made on their homepage. That's actually why I went with them over some other brands, wanted to support that.

Thinking about getting some British Thermals base layers vs some from Uniqlo. Are these worth the extra cash? Like, significantly warmer or better quality?

L Lisa W. 1 month ago

I've got both. Uniqlo is fine for everyday mild cold, but British Thermals are definitely a step up for real warmth, especially their brushed cotton stuff. The quality feels more robust too.

G Gwen 1 month ago

Honestly, yes. Uniqlo is good for the price point, but if you're talking proper cold or something for outdoor activities, British Thermals feel way more substantial and insulating. It's an investment, but they last.

How fast is express delivery to, say, Miami, Florida? Need these before a skiing trip in about a week and a half.

G Greg Beaumont 1 month ago

Hmm, they're based in the UK, so a week and a half for express to the US might be cutting it close. I'd definitely check their shipping page really carefully for international delivery times. They might even say it's not guaranteed.

M Megan C. 1 month ago

Mine took a bit longer than I expected to California even with standard. For express to Miami in that timeframe, I'd probably contact their customer service directly before ordering to be super sure. International shipping can be unpredictable.
