Nikwax BaseFresh



A great way to bring baselayers back to life and remove nasty smells

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.

Nikwax BaseFresh is a deodorising conditioner for baselayers and it works really well, removing smells and restoring breathability.

  • Pros: Effectively deodorises, helps restore breathability
  • Cons: Nothing

At this time of year baselayers are, for most of us, an absolute necessity regardless of when or where you're riding. The problem is, after a few rides they will begin to smell no matter how often you wash them. This is where Nikwax BaseFresh steps in. As a deodorising conditioner, its aimed at removing the bad odours and renewing the qualities that made your baselayers great when you first bought them.

It's simple to use: you can add it in like a fabric conditioner with your regular wash or use it as a separate treatment. I tried it both ways and was impressed with the results.

It's quite remarkable how baselayers I previously avoided because they smelt or would begin smelling quickly, suddenly didn't. I used it on different materials, from 100% synthetic baselayers to merino wool, and it worked really effectively on all.

Nikwax claims it increases breathability and wicking, too, and I did notice an improvement in both, though I can't put a number or percentage on this. Given that you tend to lose this over time, it was more noticeable on older garments and really was an 'Oh yeah, this is what it used to be like!' moment.

That makes the £4 for a 300ml bottle (I tested sample sachets) a really good price, not just against the price of normal fabric conditioners but because you don't need to replace your favourite baselayer because it stinks. It is honestly difficult to find anything bad to say about it. It's a really good product for anyone who likes to wear a baselayer.

A conditioner for baselayers which aims to bring back breathability and wicking while also removing the smells that build up over time.

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

Nikwax lists:

Nikwax BaseFresh® refreshes your base layers by deodorizing and maintains freshness by preventing odor build up when in use.

Nikwax BaseFresh® enhances and revitalizes the wicking properties of base layers and everyday clothing, increasing breathability. This helps the fabric to spread sweat, dry quickly, and keep you more comfortable in all conditions.

Nikwax BaseFresh® treated fabrics are more resistant to stains and day-to-day soiling. Should soiling occur, fabrics treated with Nikwax BaseFresh® are easier to clean.

Nikwax BaseFresh® allows base layers to be cleaned with standard laundry using conventional detergents, removing the need for a separate wash.

Nikwax BaseFresh® allows the use of aggressive detergents and cleaners to remove stubborn stains, such as chain oil, without compromising the performance of base layers.

Rate the product for performance:

Does exactly what it says it would: removed all smells from my baselayers and brought back breathability and wicking ability.

Rate the product for durability:

In terms of the effect on clothing, it lasts well – baselayers that previously began to smell quickly, didn't.

Slightly more expensive than regular fabric conditioner, but when it saves the much larger expense of a new baselayer, the value improves dramatically.
