We have now reached the final part of our Thermal Tights, Revisited series.
So far, we’ve looked at five different thermal tights from some of the most visible Chinese brands — turning them inside out, examining the construction, and then putting them on a real body.
For the final comparison, we’re looking at Bananain (蕉内) and MOUTION (茉寻).
At first, these two brands may not seem like an obvious pair.
Bananain started with underwear and basic apparel, building its identity around “body-sensing science” and redesigning everyday essentials. Since launching in 2016, it has expanded into underwear, socks, thermal wear, homewear and light outdoor products. Its “Heat Skin” thermal range is one of the product lines through which the brand applies this philosophy.
MOUTION comes from a rather different direction.
Founded in Nanjing in 2019, the brand positions itself around fashionable light outdoor apparel, with a focus on balancing technical functionality, comfort and design. Its product range now covers apparel, underwear and accessories across light outdoor and everyday scenarios.
So why put these two together?
Because when we looked at their Fall/Winter thermal tights, we found an interesting common point:
Despite coming from very different brand backgrounds, both chose a surprisingly similar material direction.
And that makes the comparison particularly interesting.
When two brands choose similar raw materials, the real question becomes:
What else do they do with them?
Because the same fibre combination does not necessarily create the same product.
Yarn selection is only the starting point.
The knitting structure, fabric density, finishing, brushing, dimensions and garment construction can completely change how the final product looks and feels.
So let’s take a closer look.
A Similar Material Foundation
Looking at the fibre composition, the similarities are quite clear.
Both products combine the more conventional polyester, viscose and elastane with two additional fibres:
acrylic and wool.
That is an interesting combination for thermal hosiery.
Viscose contributes softness and a comfortable hand feel.
Elastane provides the stretch and recovery needed to keep the garment wearable on the body.
Acrylic is widely used in thermal products because of its lightness, softness and ability to provide warmth.
And wool brings another familiar set of characteristics — warmth, softness and a more natural hand feel.
So both products are using a mixture of synthetic and natural fibres to move beyond the traditional “synthetic thermal tight” formula.
And there is an immediate difference in the hand feel.
The brushed interiors of both products are noticeably soft and fluffy.
The acrylic and wool content appears to work particularly well with the brushing process, creating a plush surface without requiring an extremely thick garment.
Again, the goal is familiar:
Warmth without excessive bulk.
But from this point onward, the two products start to diverge.
Bananain: A More Traditional Hosiery Construction
The Bananain tights use a fairly conventional circular-knitted hosiery construction.
From a manufacturing perspective, there is nothing particularly revolutionary here.
Because the circular-knitted tube has a relatively limited circumference compared with the width required through the panty area, the product uses a back panel to provide additional room.
This creates two additional seam lines at the back.
We saw a similar construction in the SIINSIIN tights in Part 1.
And that gives us an opportunity to revisit an earlier question:
Does the presence of a seam necessarily mean discomfort?
Not necessarily.
The real test is how the seam behaves relative to the surrounding knitted fabric.
We’ll come back to that when we put the tights on.
MOUTION: A Very Different Construction
MOUTION takes a more interesting approach.
Although the product is still based on hosiery-machine knitting, it uses a one-piece construction, which the brand describes as a seamless structure.
The basic concept is familiar in the hosiery industry.
Instead of constructing the garment as a conventional tights body with a separately formed panty section, the knitting process creates the two legs as part of a continuous structure, with the panty area subsequently opened and finished with a knitted waistband.
In other words, MOUTION is essentially applying the one-piece / seamless hosiery concept to a thermal leggings silhouette.
What makes the construction particularly interesting is the proportion.
The panty area is relatively short, while the top band is unusually high.
Before trying it on, we had one obvious question:
Would such a short panty and high waistband stay in place during movement?
Or would the garment gradually pull downward and create a feeling of “drop” during wear?
There was only one way to find out.
The Brushed Interior
Inside, the two products once again look remarkably similar.
Both use a brushed thermal surface.
And because both products include acrylic in the fibre mix, the brushed layer feels particularly fluffy and soft.
This is becoming a very clear direction in China’s thermal hosiery market.
Instead of simply increasing fabric thickness, brands are increasingly trying to create a soft insulating layer close to the skin.
The interesting part is that the same basic thermal principle can support very different product concepts.
The material provides the warmth.
The construction determines how that warmth is delivered on the body.
Small Details Matter
Bananain’s Foot Construction
One of the details we particularly liked on the Bananain product is the anti-slip structure on the sole.
A conventional anti-slip hosiery construction often uses raised knitted structures to increase friction between the foot and the inside of the shoe.
Bananain takes it a little further.
Instead of relying on one simple raised texture, the sole combines recessed and raised structures, creating multiple changes in surface texture.
The idea is simple:
More variation in the surface can create more points of friction.
It is a small detail.
But it is exactly the kind of detail that can make a difference in actual wear.
MOUTION’s Foot Construction
MOUTION takes a much simpler approach.
There is less surface-texture design on the sole.
Instead, the foot area is visibly tightened to create a more fitted shape.
It looks clean and technically simple.
But again, the question is whether the construction works once the garment is actually worn.
Bananain’s “Tagless” Logo
There is another detail that is very characteristic of Bananain.
The logo and product information are printed directly onto the garment rather than relying on a traditional sewn-in care label.
Bananain built part of its early product identity around its Tagless approach, using printing to eliminate the irritation associated with conventional labels.
For the consumer, the benefit is obvious.
There is no care label rubbing against the skin.
And there is no need to cut the label off after buying the garment.
It may seem like a small design decision.
But this is actually very consistent with Bananain’s broader “body-sensing” philosophy:
Remove the small things that make a basic garment uncomfortable.
MOUTION’s Simpler Solution
MOUTION takes a simpler approach.
The brand uses pre-dyed white yarn to knit its logo directly into the waistband.
It is clean and visually straightforward, and it also avoids the need for a sewn-in label.
The limitation is that a knitted logo can communicate much less information.
It works well for the brand identity.
But compared with a printed label, it cannot easily carry additional care or product information.
Again, neither approach is necessarily right or wrong.
They simply prioritise different things.
Now, Let’s Put Them On
We used the same model as in Part 2:
168 cm and 60 kg.
This gave us another useful opportunity to see how these different constructions behave on the same body.
Bananain: Comfort Is the Strongest Point
The wearing experience was extremely positive.
The overall comfort is close to what we would describe as excellent.
Most importantly, the back-panel seams — the very feature we were initially watching carefully — did not create any noticeable restrictive feeling.
The seams move naturally with the surrounding fabric.
And the brushed interior feels warm and soft without becoming stuffy.
This is one of those products where the construction choices make more sense once the garment is on the body.
The product is not doing anything spectacular from a knitting-technology perspective.
But the combination of material, brushing, dimensions and construction produces a very comfortable final garment.
In that sense, it fits Bananain’s broader “body-sensing science” positioning quite well.
The Foot Is Particularly Well Done
The foot area was another highlight.
The fit is very good.
It feels secure without becoming tight, and it doesn’t create the bulky feeling that thermal tights can sometimes have around the foot.
More importantly, the textured sole really does seem to improve grip.
This is a good example of a small construction detail translating into a noticeable wearing benefit.
What Could Be Improved?
There are, however, a few details that could still be improved.
1. Foot Dimensions Need Better Consistency
The two feet of the same pair are visibly different in height.
The difference does not have a major impact on comfort when worn.
But it is clearly visible when the garment is laid flat.
For a product with this level of attention to construction, it is a detail worth correcting.
Dimensional consistency is still part of product quality, even when the consumer may not immediately feel the difference.
2. The Knee Area Has Some Excess Fabric
There is also some extra fabric below the knee.
When worn, this creates a tendency for the area to form small wrinkles.
This may sound like a minor point.
But we don’t think it is simply being overly critical.
The knee area is one of the most visible parts of a pair of tights when worn.
A better control of the knitting dimensions around this area could make the overall appearance cleaner.
3. There Is Still a Slight Machine-Oil Odour
There is one issue that is much harder to overlook:
a slight machine-oil smell remains in the brushed fabric.
This is not something we would expect from a finished thermal tight.
The brushing process can involve machinery and lubricants, but the final garment should receive sufficient cleaning to remove any residual odour.
A thermal tight can be technically warm and comfortable.
But if the first thing the consumer notices after opening the package is a faint machine-oil smell, the wearing experience has already been affected.
This is an area where stronger washing and finishing control would be worthwhile.
MOUTION: The Construction Works Better Than Expected
The overall wearing experience of the MOUTION tights was also very good.
The fit is comfortable and the garment feels well balanced on the body.
But the biggest surprise was the waistband.
The Short Panty Doesn’t Drop
Before trying the product on, we were genuinely concerned about the extremely short panty section combined with the high top band.
On paper, it looked like a construction that could potentially create a tendency for the garment to move downward.
In actual wear, however, that concern did not materialise.
The garment stays comfortably in place.
There is no obvious pulling-down sensation and no significant discomfort around the waist.
That is a good reminder that a construction that looks unusual on the table does not necessarily behave badly on the body.
Sometimes the only reliable test is simply:
Put it on. Move around. See what happens.
What Could Be Improved?
1. The Foot Needs Better Anti-Slip Control
The biggest weakness we found was the foot.
The anti-slip performance is poor.
During wear, the toe seam gradually moved from its original position and ended up underneath the foot.
This was actually something we were concerned about before testing, because the foot construction does not provide the same kind of textured friction surface that we saw on the Bananain product.
A more deliberately designed sole structure could significantly improve this.
The comparison with Bananain is useful here.
Both products use similar thermal materials.
But a relatively small difference in foot construction leads to a very different wearing result.
2. The Back Shaping Structure Needs More Work
The rear panty area also includes a shaping structure designed to create a lifting effect.
Laid flat, it looks quite convincing.
But once worn, the actual lifting effect is relatively limited.
This may require further optimisation of both the knitting structure and yarn combination.
The visual design communicates the intention clearly.
The next step is making sure the construction produces a noticeable result on the body.
A Final Look
After three articles and five products, we have now looked at thermal tights from very different Chinese brands.
And perhaps the most interesting thing is how different the products can become even when they are solving a similar basic problem:
How do you make thermal hosiery warmer without making it bulky or uncomfortable?
Bananain and MOUTION approach that question from different construction directions.
One relies on a more conventional circular-knitted structure and pays close attention to comfort and small functional details.
The other uses a one-piece construction to create a different silhouette and wearing experience.
Both use a similar material philosophy.
Both use brushed interiors.
But once the products are put on a real body, the differences become much easier to see.
And that is where we’ll leave this series.
Because in the end, a thermal tight is not really defined by its fibre composition, its knitting machine, or even the technology written on the product page.
The real test is what happens when you put it on.
