It is not warm.

I purchased it because i thought it will be warm but it is very normal. So if you purchasing it with the thought that it will give you heat,dont buy it.

Hello Javaid

Thank you for taking the time to give your valuable review. We are sorry that you were not satisfied with the product. This base layer is designed for Ski and hence along with warmth moisture management and reducing chafing is also its major technicity as you are very active while skiing. However, we understand that if you bought these for normal purposes when you are static and not in too much action the level of warmth would not be great.

We apologise for not being able to guide you during the time of purchase, Please feel free to return the product at your nearest Decathlon store or via your Decathlon mobile app.

Gem of product, unlike other brand normal thermals made of cotton or polyester, it is made of polyamide so NO RASHES and ITCHING; HEAT MAPPED so not SWEAT LOGGING, ODOR or WET FEELING -balance of warmth and perspiration wicking, so suited for ACTIVE SPORTS- DRIES FASTER. Unique feature- We can wear WHILE TREKKING (can't do this, with other thermals-which will make us feel overheated, suffocated & ultimately our sweat itself will make us feel chill) and of course, in night while sleeping. Add on feature, with good body hugging elastane, they act as COMPRESSION T-shirt, which means FASTER MUSCLE RECOVERY after a tiring trek/hike, ask any sportsmen compression tees advantage. Yes, bit of wobbling, but I researched, design wise doesn't affect core functionality, infact normal for a thermal or sweater (in any case this is base layer we sleep with this on, and we wear fleece/ jacket etc over it). This unique weaving and wobbling helps it to trap more air and thus better insulation of body heat and prevent outer cold getting in. Difficult to balance warmth and sweat absorption with such a thin fabric- Technology put in use:) LOVED IT. Worn this during Buranghati and Sandakphu trek- Must buy and try yourself, HIGHLY RECOMMENDED. (Guess what my wife who also wore the female version of this product agreed on this- that doesn't happen, often :):)

Good Quality and value for money

Отлично за спорт на открито

Блузата е много удобна и приятна като усещане върху кожата. Много добри показатели за спорт в късноесенните студени утрини и вечери. Допълнително може да се облече и още един слой за по-добро запазване на топлината. Дори и да задържи влага усещането не е неприятно. Отличен продукт.

Additional Product Information


Main fabric

  • 97% Polyamide
  • 3% Spandex

I-soft underwear is what type of fit?

I-Soft underwear is SLIM fit. It is like a second skin that hugs the body, which limits rubbing.

What are the benefits of polyamide?

Polyamide has the highest strength of all textile raw materials (even when wet) and is very stretchy. This breathable fiber enables very good moisture management, reducing odors thanks to its natural properties as well as good temperature regulation. These specially textured super-soft yarns give fabrics a silky, natural feel. Ideal for tight, seamless clothing.

Technical structure of the product

Thanks to its intelligent bodymapping and brushed polyamide fiber created from I-SOFT technology, this second skin will ensure you feel a warmth that is distributed evenly over the whole body.

What is i-soft technology?

I-soft technology increases the performance of the fabric via different benefits: soft, feeling of warmth, comfort for the skin. Also, it increases the performance of the product with better thermoregulation, the absorption of damp and thermal insulation. To achieve this softness, the base layer is brushed.

What is i-band technology?

An innovation located at the waist, enabling the fabric to always be well positioned so that it does not ride up when practicing. Also, the top and bottom of our i-soft are equipped with this technology, so that all you have to worry about are your holidays.

How should you dress to stay warm on the slopes?

All you need is 3 technical layers to stay warm on the ski slopes. Layer 1 or second skin, to stay dry. Layer 2, or insulating layer, to conserve heat. Layer 3, or protective layer, to protect against bad weather.

An environmental rating of the product
