Primal Men’s eSport Bib Shorts



Well-thought-out and comfortable shorts for the indoor racer

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Designed for indoor training, the Primal eSport bib shorts have some clever tweaks to make them more suited to your garage rather than the outside world. Fewer seams, a decent pad and breathable materials make them ideal for going nowhere fast.

  • Pros: Soft shoulder straps; pad is good for sitting in one position over time
  • Cons: Very high front panel

For some of us it's getting near that time of year when the turbo trainer will be getting a dusting off and the direct debits for the interactive training software packages will be resumed, and this is where Primal sees its eSport bibs coming into play. They are like a lighter, stripped down version of the shorts you'd normally ride out on the road.

First up, the fabric feels a lot thinner. The Vita material is soft and highly stretchable but with plenty of compression, ideal for those full-on interval sessions.

Unless you have one of the new fully immersive turbo trainers that allow the bike to move around beneath you, you're going to be sat in one position for a long time which can increase the likelihood of irritation. Primal has made the eSports from just four panels to cut down on the need for so many seams. This does mean they don't have such a contoured fit as a quality multi-panelled pair of shorts, but the compression in the fabric more than makes up for it, reducing any bunching of the material.

The only thing I would say about the cut is that I found the front very high, almost squashing my stomach at times because of the compression in the material, and a little uncomfortable when in the drops.

For those long efforts in the saddle you're also going to need a decent chamois to ward off numbness. Here, the E6 Carbon pad does a pretty decent job. There are various density layers and channels to promote blood flow, and on the whole it worked quite well. Even though it is relatively thick I didn't find it the most cushioning of pads – not a major concern when on the turbo but if you were to wear them on the road (this pad is used in some of Primal's road shorts) you'll notice that they don't damp surface imperfections that much.

On the turbo is the only place I don't wear a baselayer, so it's good to see that Primal has given some consideration to the bib straps. They are lazer cut for a start, which means no seams anywhere to rub against bare skin, and they are plenty wide enough to avoid hot spots. They have small ventilation holes, but you are still going to need a decent fan to keep you cool.

Value-wise it's tricky to rate the eSports, as it comes down to how much you are willing to spend on kit that you are going to use indoors only.

As I said earlier, they are just a little thin and don't quite have the right cut to be massively comfortable when riding outdoors, so £95 could be a little steep.

If you are an avid Zwifter, though, these might be the only shorts you wear for three to four months of the year.

For £75 you can get an excellent pair of dhb Aerons. I've worn these on the turbo many times in the past without any real issue.

Or there are the Lusso RS19 bibs, which are very slightly more than the eSports at £99.99.

You can obviously use both the dhb and Lusso shorts out on the road, but I have to say I did notice small improvements when using the Primals on the turbo over standard bib shorts, in both fit and comfort.

If you ride the turbo a lot then they make a lot of sense.

Tell us what the product is for

Primal says, "The eSport Bib Short is comprised of a lightweight fabric with reduced seams and designed for those who want to push themselves during their indoor training sessions. Using four panels, with fewer seams to reduce irritation, the eSport Bib is a product that is designed to fit your body and not scrunch during a ride. This is achieved through the FlexBib straps which feature laser incisions, not only ensuring a tight fit, but also providing additional ventilation when the fabric is stretched. As a result, this perfectly finished fabric results in no hotspots or pressure points. The MARC woven leg bands additionally have strategically placed silicone to provide the perfect amount of grip which prevents the moving of the shorts. In addition to these excellent features, the Italian made E6 Carbon chamois is suited for comfort, allowing you to put in more hours during your training. "

How easy is the product to care for? How did it respond to being washed?

These got washed a lot considering how hot and sweaty turbo training is this time of the year, and I had no issues.

Tell us how the product performed overall when used for its designed purpose

There are definite improvements on the turbo over normal road shorts.

Tell us what you particularly liked about the product

Bib straps are cleverly designed.

Tell us what you particularly disliked about the product

High front can be restrictive.

How does the price compare to that of similar products in the market, including ones recently tested on

We've seen very few indoor-specific shorts to make a really good comparison, but for the build quality and materials used I'd say the eSports aren't overpriced compared with other mid-level shorts from the likes of Lusso and dhb.

After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!

And why is a helmet being worn for indoor training? If you don't require a pair of normal shorts, then surely tou don't need a helmet. angel

You'd want the ventilation slots in the helmet otherwise you'd overheat.

It's an indoor specific helmet, will be pushing the review out shortly once they've finished reviewing the 100th pair of primal shorts.

I hope they get around to reviewing the trainer light set as well.

Indoor training is crying out to be done in Speedos.

Jetmans Dad | 4 years ago

Have to agree, ped. 

All my indoor training is done in old, cheap or battered and worn out shorts that I used to ride in outdoors ... on the basis that only my wife will see me in them. 

Never had  a problem with irritation or anything else.

A fool cyclist and his money are soon parted.

I'm not seeing anything in the review that justifies the 4/5 rating nor has me believing there's a need for indoor bibs or that these meet any specific indoor cycling requirements.

If you've got the spare cash then fair enough, but for the majority of us surely it's better to spend your nigh-on hundred quid on some proper bibs, and relegate an old 'outdoor' pair for use indoors? I've 10+ year old bibs that the lycra's so worn and transparent as to make wearing them outdoors a near-arrestable offence but the pad still works just fine for an indoor sesh. 

This said, we're a sport of niches so I'm sure there'll be buyers: I'll wait on the indoor gravel TT skinsuit.
