Does the job well

Fits really well, may be a bit longer than expected, but on the whole a good bit of kit.

Excelent baselayer, adds fantastic warmth in any cool conditions, whilst wicking sweat and keeping me dry. Love wearing this.

Base layer, aerofit 700 short sleeved cycling top

I have 3 of these, they are excellent value, the 1st one I bought has been washed countless times and is still as new.

Second skin

A must. you don't feel it when it's on you, Although it keeps you very warm and evacuates well the perspiration. doesn't get soaked like other base layers i have used

Very disappointing

As another reviewer has indicated, the body on this top is too short. Perhaps two sizes larger would be ok?

Dear Sir,
Your comment is duly noted on the length and has been fed back to the product manager. The previous reviewer suggested that when riding the bike that the length is fine. I have checked other sites as well as the UK site and the product is generally well received and is very effective when on the bike.
If the fit is not quite right then of course please feel free to return it to us for a refund/exchange.

Good baselayer

Perfectly good baselayer at a competitive price. It fits well, is nicely warm whilst also wicking well, I've used in both warm and cool conditions and it is fine in either. It seems well made and if it's anything like most 700 series Decathlon stuff will last for a long time and outperform kit that costs twice the price. Only minor complaint is that it is a little short, not an issue once you get on the bike but does look a little off when you're off it.

Great baselayer

Very impressed with this. Went for a ride and only realised when I returned home how well it was wicking away the sweat. Fabric is cofortable against the skin as well

Excellent base layer

I bought this for summer cycling when I didn't want to wear my firm compression tops. This top comes up to the quality of the rest of the Aerofit range really well and has worked on the hot days with excellent wicking properties and it has also added a layer of warmth as the chill starts to come into the morning air.

Super bequem, super Tragekomfort. Habe es in der L bestellt und mir ist es bei 190cm Körpergröße zu kurz, sonst gibt es nichts zu beanstanden.

perfekte Passform

habe das Shirt als Baselayer bei einem Iltramarathon getragen. Klasse Passform, kein scheuern, nichts. Gleich nochmal gekauft.

sehr zufrieden

schnell trocknend, gut Schweiß absorbierend sowie super Passform


Super Preis-Leistung. Das Shirt ist wirklich klasse. Gerade beim Sport schwitze ich sehr viel und ich bin trotzdem trocken am Körper da die Feuchtigkeit sehr gut absorbiert wird.


Schön eng anliegend und transportiert den Schweiß gut nach außen. Man hat auch nach langen Einheiten nicht das Gefühl das etwas kaltes nasses auf der Haut klebt. Für den Preis Top.


Trägt sich wunderbar

Additional Product Information


Main fabric

  • 97% Polyamide
  • 3% Spandex


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 vapor produced by the body escape, and therefore the more breathable it is. For example: RET <9 = extremely breathable fabric.

Care tips

Machine wash at 86°F. Synthetic cycle. Turn the article inside out. Use a minimal amount of laundry detergent. Do not use fabric softener. Line dry in a warm, ventilated area. Do not tumble dry. Do not dry clean. Do not bleach. Do not place on a heater to dry.
