OneTen Knee Warmer



Knee warmers that don't keep your knees warm aren't really knee warmers

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 OneTen knee warmers are manufactured using a circular knitting process much like their arm warmers, although these do have a seam running down the side (despite OneTen's claims to the contrary). The seam itself lies flat against the surrounding material so it shouldn't pose any risk of irritation. I also liked how OneTen have refrained from adding any annoying labels to the inside of the knee warmer, printing the care requirements on the hem instead.

The number of different weaves used is particularly impressive - I counted 6 including the hems. As a result, the knee warmers are right and left leg specific as well as pre-bent. A synched down weave behind the knee should help prevent bunching while a more open weave on the front helps it flex as you pedal.

Given this shaped fit, it's somewhat surprising that OneTen have chosen to go with a one size fits all approach, given the range of human body shapes. Upon first putting them on though, I was pleasantly surprised by their fit as they were long enough, but also tight enough to suit my lanky frame. The stretchiness of the fabric also means that they wouldn't squeeze the life out of someone thicker-thighed either.

Unfortunately, in use the lack of silicon leg grippers means that they begin to ride up behind the knee almost immediately. For those with shapelier calves, this effect is likely to be even more pronounced. The upper hem doesn't grip that much better and I found I had to continuously pull them up while riding. Due to the open weave, these aren't the warmest either which limits when they can be used.

The white colour tested was pretty much a no no when the roads were even the slightest bit wet, but they are also available in a much more UK friendly black. At £24.99, these are pretty much middle of the range in terms of price, but their below par performance and lack of warmth makes them poor value for money.


The OneTen knee warmers' tendency to bunch behind the knees makes them uncomfortable to use and their lack of warmth seriously limits when you could wear them anyway.

Rate the product for quality of construction:

The knee warmers feature an impressive array of different weave styles but there were some loose threads around one of the hems

Rate the product for performance:

They bunch up behind the knee almost immediately and don't grip to one's thighs that well either. Their open weave makes them draughty too.

Rate the product for durability:

After only a couple of washes, some of the elastic threads around the hems have come loose.

Rate the product for weight, if applicable:

Although these are very light, that does come at the expense of warmth

Rate the product for comfort, if applicable:

The fabric is nice and soft on the skin, but they don't stay in place when riding.

Rate the product for value:

Their poor performance makes them poor value even though they aren't the most expensive out there
