Reviews Secret World | Thermal Underwear Set Warm Women – Real User Experiences

I'm buying my third set of these, so no need to say much—I'm definitely a fan! I hope they come out with a men's version because I'd love to get a few sets for my husband. I'm just waiting for him to come back from his trip to see how much my size M shrunk. If it didn't shrink too much, I think he'd fit in a L size, so I'll probably get him a few of those too!

The fabric feels really nice, and after trying it on, I found it warm and not cold at all. The neckline is a bit loose, and the pants are slightly long, but overall it’s pretty comfy.

This is the kind of fitted base layer that feels really soft against the skin, much softer than regular thermal tops. The sleeves are a bit short and the neckline is pretty wide, so it's quite discreet when worn underneath. In northern areas, you can wear it alone with a cotton jacket, but it's better to layer it with a sweater and then a heavier coat for extra warmth.

The material is comfortable and warm, and the wide neckline doesn’t interfere with layering clothes on top, which is great.

I bought this on a whim, and I was pleasantly surprised. The fabric is really comfortable, and the craftsmanship is great!

The quality is really great! I bought from three different places, and this one is definitely the best. It's super comfy, and the sleeves are just the right length—not too long at all!

The clothes feel super comfy when you wear them. The fabric is really soft and doesn't irritate the skin at all. It's easy to move around in, and the color looks great! 😘

The clothes are very comfy, a bit oversized but still okay. The customer service is great and the seller's attitude is very good, really good! 👍🏻

These thermal tops and bottoms are so comfy to wear! They don't feel tight at all and give a nice, relaxed fit, almost like you're not wearing anything.

This is super soft and warm against the skin. The quality is excellent. Out of all the autumn shirts I've bought over the years, this one is the best. It doesn't dig in or lose its shape after washing. I rarely leave reviews unless something really impresses me, and this definitely does. It's worth it!

The clothes are super comfortable to wear, the fabric is really soft, and it feels great against the skin. I can move around freely in them! 😍😍

This is a skin-tight top that feels really soft, even softer than regular autumn base layers. The sleeves are a bit short and the neckline is on the larger side, but it’s quite discreet when worn underneath other clothes. In the North, you might want to wear it under a heavier coat for warmth, but it's super cute in pink!

It's warm, but my girlfriend mentioned that it might fade a bit, and when worn with jeans, it did transfer some color. Maybe a different shade would be better.

The clean packaging made me like the brand right away, and the fabric feels nice and soft, though I haven't worn it yet.

I was originally planning to order two sets right away, but I decided to get one set first to test it out. It's really comfortable and fits well, so I would buy it again.

This is my second purchase, and it's super soft and comfortable. Wearing it feels amazing, and I can't stop buying it!

The thermal wear is seamless and really warm! The neckline is a bit loose, so it would be better if it were a little tighter, otherwise it might slip off the hanger when the wind picks up. Thanks!

Super comfy, I've never worn such cozy long johns before, they're amazing, feels like I'm not wearing anything, warm and stretchy, definitely recommend! 👍👍

Super handy!!! Really warm, and the fabric is so comfy. Great value for what you get, planning to buy another set later. No need for more words on how great it is!

I got this thermal underwear in black, white, camel, gray, pink, and yellow 😂 You can tell how much I love it! It's super comfy and soft, keeping me really warm. I don't want to wear anything else now, totally worth it!

This thermal underwear is super comfy, feels really soft and smooth against the skin. I have sensitive skin, and unlike other brands I've tried that were itchy and uncomfortable, this one doesn't irritate me at all. I feel like I've found a hidden gem!

Buy it!!! It's super comfy, perfect for layering when it gets chilly, and really warm. Plus, it's seamless and incredibly soft. The stretch is great too!

This was my first time trying this brand's lingerie. The quality is great and it's really comfortable to wear.

I wouldn't really recommend it. Even though it's called self-heating, it feels too drafty. It's like in the fall or winter when it gets a bit chilly, and it feels like the wind gets through. It's not as warm as regular thermal pants.

The fabric is super soft and comfy, hugs the waist nicely, and keeps me warm while blocking the wind.

Really nice! The clothes are super warm, and it's comfortable even in the southern weather. They fit well against the skin, and I really like them. The gray tights I bought from them before are also great!

I've been buying Secret World underwear since college, and this time I got a thermal top. The quality is still amazing—the brushed fabric is breathable yet warm, making it cozy to wear without feeling restrictive. The cut is well-designed, and the cuffs and hems fit nicely without riding up. Over the years, the quality has remained consistent, and it's hard not to love it!

I had bought lingerie from this store before and really liked it, so this time I got some thermal tops. The fabric feels really nice and soft against the skin, it keeps me warm without feeling restrictive. The neck and sleeve openings fit perfectly, and they’re totally invisible under a shirt, making them great for everyday work wear.

This thermal top and bottom set is super comfy! It doesn't feel tight, and it's like wearing nothing at all—it's nice and loose.

This is my second time buying from them. The first purchase was their tights, which held up well after washing. Now I've come back for some autumn clothes, and the high-waisted pants are super comfy! The fabric is soft, and they can be worn as autumn tops or bottoms, which feels great!

Super soft and comfy, like wearing a cloud ☁️. This is my third time buying them; I got white twice before and decided to go for black this time.

I’ve bought socks and underwear from this brand before, and the quality has always been solid. With the temperature dropping, I quickly bought some thermal tops. The fit is really considerate; the neckline and cuffs are snug, making them completely invisible under my coat. I can take off my outer layer in an air-conditioned room without feeling awkward. This long-established brand consistently delivers high quality, and it's hard to find better value for the price. I'll definitely keep buying from them in the future.

This fabric is different from the black one; it's thinner and has a higher neckline. I got it specifically to wear under light-colored outfits.

It's really comfortable and super stretchy, friendly even for someone tall with long arms and legs like me. I threw it in the washing machine, and there was no fraying at the cuffs or pants. As soon as I put it on, I could feel the warmth. Plus, it came with a nice antibacterial spray.

The fabric is soft and feels great on the skin, really comfortable to wear, and the quality is excellent.

It's a skin-tight fit that's pretty soft, softer than regular thermal tops. The sleeves are a bit short and the neckline is quite wide, so it stays hidden underneath. In the North, you can wear it alone with a cotton jacket, but it's better to layer it with a sweater and a thick coat for added warmth.

I used to wear pure cotton thermal tops, but this year I tried the Darlon ones and wow, what a difference! They're just as fitted, but way warmer without being bulky, so I can wear a snug sweater in winter without feeling heavy.

I have sensitive skin, and wearing some thermal underwear can make me itch. But this set is totally fine; the inner fleece is really soft, and I can wear it all day without any discomfort. I even got a camel-colored set to switch things up!

I bought it again! It's another layer of soft fleece, super comfy to wear as a base layer. Highly recommend!

The quality is really good; I bought from three different places, and this one has the best quality. It's very comfortable, and the sleeve length is just perfect—not too long at all.

The fabric feels so warm to the touch, and after a shower, it doesn’t feel cold at all; it’s super cozy to jump right into bed with it. It has great elasticity, so even with bigger movements, it’s comfortable without feeling tight. Plus, it even has antibacterial properties, which is perfect for someone like me who doesn't want to wash it every day during winter. It stays fresh even after sweating, so I can wear it for a few days and still feel great.

It's the kind of fitted base layer that hugs your skin, really soft and cozier than regular thermal tops. The sleeves are a bit short and the neckline is a bit wide, but it’s great for layering. In the north, it doesn’t quite keep you warm enough on its own with just a cotton coat, so you'll want to add a sweater and a thicker jacket on top. The pink color is really pretty!

I bought my first product from this brand last summer—a lingerie piece—and I was so impressed that I also got some of their thigh-high socks. This time, I bought tights, leggings, winter and summer socks, and underwear. Their products are great quality, and the customer service is responsive and helpful. I definitely recommend trying them out! The picture shows everything I bought this time. Even though the leggings look thin, they're really warm!

Spending winter in Beijing is easy with this outfit; just wear it with a fur coat on top and you're good to go. It's warm without being bulky, and you won't feel stuffy on the subway. It's really practical for commuting.

I've washed it several times and it still holds its shape and color. The fabric is definitely durable, and even with frequent washing in winter, it doesn’t get loose or saggy.

This thermal underwear is made of thin fleece, perfect for wearing in temperatures around 5-10 degrees. If it gets colder, you’ll need to layer up more, but overall, I'm really satisfied. It would be great if there was a thicker fleece option available.

The quality is really great, I love it, it's very warm, and it feels super comfortable to wear as a set.

The clothes are really thick and fit well, the fabric is soft. I got both the black and pink ones and I love them!

It feels soft and cozy, and it's pretty warm to wear. I just think wearing a bit more fluffy clothing to fill the gaps between layers would make it even warmer. It's perfect for use in Yunnan!

The size L has shorter sleeves, and the neckline is quite loose, which might lead to some shape changes.
