Prendas Ciclismo Merkalon Special Edition Armwarmers



Seamless synthetic arm warmers that provide a middling level of warmth at an exceptional price

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Prendas Meraklon arm warmers are basic but they do a good job and come at an amazingly cheap price.

They're essentially tubes of polypropylene (58%), nylon (40%) and elastane (2%) with a ribbed top and a more tightly woven cuff section at the bottom. A little more air gets through than with fleecy roubaix fabrics but they're warmer than skinny Lycra warmers – they split the difference between the two. I found them a good option for typical spring/autumn conditions.

These arms don't get heavy with moisture no matter how hard you sweat. Just a little bit of airflow keeps them dry and comfortable even on hot climbs – and, obviously, if you do start to get too warm you can just push them down to your wrists or take them off altogether.

There's no gripper inside the top – no silicone or extra elastic – but the ribbing holds them in place well. I've got long arms so went for a size large (they come in small and medium too) and they stayed up fine despite skinny cyclists' biceps, and there's plenty of stretch in the fabric should I ever start pumping iron.

These are seamless, knitted like socks, so there's not a lot to cause discomfort. I found that the very end of the warmer inside the top would tend to curl up and cause a ridge... but these cost £7.95, so who cares? Chances are that you'll get your money's worth because the fabric is tough enough to survive scrapes and rattling around in your jersey pocket with your multi-tool.

The Meraklon arm warmers are available in several different colours (black, white, blue and red), and in Special Edition versions matching the Special Edition Socks we recently reviewed featuring world champion and national champion stripes (all the same price).

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Prendas say:

"Made from the same versatile "Merakalon" fabric as our highly acclaimed Prendas over socks, these armwarmers offer the perfect intermediate solution between seasons when a pair of Santini Roubaix arm warmers or a long sleeve jersey is too warm.

They breathe well, are quick drying and roll up/down easily, also fold up very small so will fit in a jersey pocket with room to spare.

Made in Italy with a stay fast cuff and a construction that means that they will not slip down, they come in 4 colours.

The size S is some way shorter than the M and L and is ideal for ladies and those with thin arms although the M will usually be OK too for those who need a little more length. L is usually only required for a beefier/longer arm.


- Lightweight

- Made in Italy

- Exclusive to Prendas!

- Multi-Season, Multi-Use

- Breathable and flexible fabric"

That's about the size of it. I don't think Prendas are making any great claims about these being luxury arm warmers. They're simple, they work, they're cheap.

Tell us some more about the technical aspects of the product?

These are largely polypropylene which is good at transporting sweat away from your skin. Polypropylene can often retain odours but that has not been a problem here.

Rate the product for quality of construction:

They're seamless tubes. There's a slight ridge around the top where the edge of the fabric curls over; I'd rather wasn't there but for £7.95 you really can't moan.

Rate the product for performance:
Rate the product for durability:

Arm warmers generally last ages because they just sit there not really moving much. These look like they're going to stay the distance.

Rate the product for comfort, if applicable:
