Technical Information

Component's warmth
Ability of a product to offer protection from the cold.This ability depends on the thermal resistance and the air resistance of the component. The higher the thermal resistance, the more the product keeps the heat produced by the body while cycling.
To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092). The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is. For example: RET < 9 = extremely breathable fabric.
Care tips
Machine wash at 30°C. Synthetics cycle. Use minimal laundry detergent. Do not add softener. May undergo a second rinsing cycle. Hang to dry in a warm, ventilated place. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.
Product tests
Our team of product designers based at the B'Twin Village in Lille is continuously working to make cycling more comfortable for our users. Our obsession is to create products that meet the specific cycling needs of our users and eliminate hindrances to a good cycling experience. We then test our products in the field, as we are convinced that only by subjecting them to real world conditions, like the ones you experience on your bike, can we continuously improve our products.

Great value
Used for 2 to 8 weeks
Apart from the sizing (I ended up with 2XL and I'm very skinny!) these are a real bargain. Well made and comfortable. I overheat in them anything over 10 degrees but great for really chilly days.
All right!
What you expect and great price. Good tights, not pro but not pretty decent, and for a really reasonable price
Thermal bib tights
Used for 2 to 8 weeks
Couldn’t turn these down for the price of them.

Good quality chamois pad and the thermal layer is a good send. The shoulder straps are a little on the short side, but my shoulders are slightly bigger than average. Other than that, happy wIth them.
Looks passable quality but very small
I'm 90kg 6ft2 ordered xxl, but way too tight, so returned to try an exchange for xxxl but starts to get expensive having to pay to return stuff that is just not the size it should be. same with gloves and mac I ordered all small and I already oversized products.
Good quality cycling product
Used for 7 to 12 months
Amazing product, warm, good quality
But size is everything.
I bought 3x size and it looks like medium. Bought cycling shorts last year same problems.wont buy any more clothing from you as sizes are useless.
Has anyone at Decathlon tried there own clothing for size. Overall if products would fit I would buy more....
Too small
Used for 1 week or less
Way too small sizing
Response of the brand
If this item is too small, please return it to us. If you could reply to me (it will be private) with your dimensions and the size you picked up so that I may forward this on to the team in charge of this item. They would find this information invaluable.

Snug fit but great quality for this money.
Used for 2 to 8 weeks
Firstly the pro-tip - I'm 5'10", 79Kg and the large is a good, tight fit even on my pipe-cleaner like lower legs, so buy an XL if you're taller/broader than that. Other than this for the money these are brilliant - the seat pad isn't as good as my other (far more expensive) bibs & shorts but for a half hour commute it's perfectly adequate. Warm enough for a cool day, not tried them on a genuinely cold ride so can't offer an opinion on that. Wore them for a month & bought another identical pair as soon as they came back into stock... for a tenner? Feels like I stole them! ;-)
Cheap price but great quality!
Used for 3 to 6 months
Great product at a ridiculous price! Second pair excellent for Spring / Autumn, quite small sized, I'm 5ft 8, 32 waist, needed large. Ordered loads of Cycling, Trekking kit from this site and all good.

Well made and decent fit but the padding is poor
Response of the brand
I'm sorry to read that the padding was not comfortable for you. We only use a basic padding in this model for moderate speed occasional riding. for more frequent use the 500 range has an excellent pad for many hours in the saddle.
