Helium Jersey - Orange


The Helium Jersey

The Helium Jersey from Band of Climbers is a super-light aero jersey designed for training in warm to hot temperatures. We've designed this jersey with the height of summer in mind, when the body needs the maximum amount of air to stay cool and perform at its best.

Using a premium, lightweight and ventilated 80g/m2 cross-mesh Italian fabric, and form-fitting silicon sleeve and hem grippers, this jersey is designed to give you an aero advantage and keep you cool in hot or humid weather. 

Three rear pockets plus a 4th zipped pocket ensures all your snacks and tools have their own space, plus a full length YKK zipper helps to add additional temperature regulation whenever you need it.

Ride as if you were air.

My first aero jersey. Tried on a 25c temperature for 90km distance.
Fabric: awesome textile construction tha has an hive like pattern. It seems as you have nothing on you from lightness.
Breathability is fabulous as you won't even fell it wet... I suppose the hive pattern is related to this because the jersey as an almost transparent look.
Fit: couldn't be better. It adjusts to the body and stays there, there is no sloping due to the perfec sleeve laser cut and fabric elasticity properties.
Best jersey I bought so far

Jonathan Simmonds
Fits perfectly and feels premium

I bought this jersey in a sale and am really impressed with the quality. The fit is perfect - I'm 183cm, 80kg of medium build and bought the medium. It's a close compression fit, like most high-end aero jerseys, but as long as you have that expectation it's perfect.

Would happily buy again (even outside of a sale).

Thomas Parsons

Super jersey and bib shorts. Very lightweight for the hottest days

Ferdian Budiarto
Nice cooling jersey

Quite a unique jersey as it's almost entirely mash polyester except for the spandex arm band. Therefore it's really a cooling jersey & great for hot weather ride. The small downside is this is quite translucent which means certain body parts might get exposed, especially when wearing one of their bib shorts where the braces keep getting twisted & unable to stay in place (see my other review). Overall, still a great jersey for short or long rides, and the colourway is just awesome, well-thought design as with most of BOC products.
