Good quality, delivery took a while

I ordered a 3-pack of men's bamboo boxer shorts. The ordering process on the website was pretty straightforward. Delivery took about 8 days to reach California, which was a bit longer than I expected, but it wasn't a rush. The boxers themselves are really comfortable and feel well-made. I've washed them a few times already and they've held up great, no shrinking or fading. The fabric is soft and breathable, much better than standard cotton. I had a small question about sizing before I bought, and customer support responded within a day, which was helpful. Overall, a positive experience, I'd consider buying their thermal tops next winter.

Value for thermal leggings

I was looking for some affordable thermal leggings for the colder months. I found FM London and noticed they had a multi-pack deal on their thermal leggings, plus I managed to get 15% off my first order. It made the price per pair really attractive compared to other brands I looked at. The leggings themselves are decent quality for the price I paid; they're warm enough for layering under clothes. It felt like a solid deal for the warmth I'm getting. Glad I found their offers.

Comfortable socks, quick ship

Got the bamboo ankle socks. Super soft and comfy. Shipped fast, no issues. I'd definitely buy these again. Good everyday socks.

Thinking of trying their bamboo socks, but I'm usually an 8.5 US women's. Should I size up or down with their sizing?

C Chris Q. 1 month ago
I'd go with your usual size. I'm a 9 and their 7-9 fits me perfectly. They're pretty true to size, stretchy too.

My husband wears an 11.5 and the 11-13 size was a bit big for him, so I think they run pretty standard.

Hey has anyone ordered from FM London to the US? Wondering how long shipping usually takes to like, California.

B Brett Marsh 2 months ago
Yeah it's legit. I'm in LA and it took about a week and a half for my last order, maybe 10 days tops.

They ship from the UK so it'll probably be a bit. Mine got to New York in like 8 business days last month. Not super fast but not horrible.
