Gore C3 Women Thermo Bib Tights+



Serious comfort and protection and an excellent zip system for speedy pee-stops

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 Gore C3 Women Thermo Bib Tights+ really do perform well in cold, dry conditions and are exceptionally comfortable. The two-zip system at the rear is also great for speedy, hassle-free pee-stops.

  • Pros: Two-zip system for easy peasy pee-stops
  • Cons: Not a lot... a bit susceptible to snagging, but that's about it

The first noticeable thing about the Thermo tights is how easily they pull on. There is no zipper at the ankle, it's not needed; the fabric is very giving and slides over the heel, and the cuffs sit securely in place even without a stirrup.

While the tights are by no means baggy or oversized, if you like very snug-fitting, compression-type tights these will not be for you. It was only around the pelvic area that I really noticed the absence of elastane – there is a tendency for the tights to bag a little here. That said, this didn't irritate me; the tights feel really comfortable both on and off the bike. The fabric is exceptionally soft against the skin and moves freely over the legs as you ride or move in and out of the saddle. The only drawback of this soft fabric is that it is prone to snagging against rough surfaces.

I am religious about protecting my knees when I am riding; they are in the direct line of airflow and are being forced to work overtime while riding. No surprises then that I love the double-layer panel that extends from the middle of the shin to the lower quad; it's a winning ingredient. The tights are not waterproof and don't incorporate Windstopper fabric in the legs, so the double layer goes a long way to protect knees from the cold air as well as splashes and road spray that can quickly penetrate a single layer.

The rear panel bucks the soft fleecy trend: it is a thinner, Windstopper, water-resistant fabric. It's well positioned and deals with spray effectively. This fabric stretches down over the rear half of the pad.

The bib is well proportioned – not too much frontal coverage; baselayers and jackets are left to do the work here. There is a mesh panel on the rear which really helps to prevent overheating.

The bib is secured across the front with a small hook fastener, holding things together securely, although I frequently forgot to fasten it and honestly didn't notice any difference while riding. The whole bib was a little generous for my liking but not everyone will have this issue.

Breathability is good, mainly thanks to the lack of Windstopper and water-resistance on the legs. You certainly build up a layer of warmth but it escapes much more freely than it would otherwise. Gore rates the tights for temperatures between 5 and 15 degrees; I found that they kept me warm in temperatures down to 2 degrees, provided I was making a half decent effort, while above 12 degrees I felt they were too much if I was putting in any serious effort. They should pretty much serve for all of your dry winter riding.

The two zip-system is the best setup that I have ever used for facilitating a swift, hassle-free pee. While halter straps are quite common, and Sarah got on just fine with dhb's halter system last winter, I personally can't tolerate a strap around my neck so I was keen to see if Gore has found a feasible alternative. Quite simply, it has, and I am not surprised to see that it is patented. The zips are easy and intuitive to reach, they easily pull open and let a sufficient chunk of the tights drop away. There is no pulling on any part of the tights when you squat or sit down and it's not a battle to 'redress' yourself: zip the sides up (one at a time worked best) and readjust your outer layers. After a couple of outings I was able to do all this with low-bulk gloves on, although thick winter gloves proved more difficult and I invariably just took them off. I never had any problems with the zips creeping open while riding.

The only downside of this brilliant setup is the gap between the two zips, which widens a small amount as you hunker down on the bike. If you are precious about keeping your lower back protected you need to ensure you have a baselayer with a long enough tail to cover up bare skin here. The Castelli Prosecco did the job perfectly but there are loads on the market that offer decent coverage. Those who aren't so precious may actually appreciate this 'vent' when working up a sweat in milder temperatures.

The chamois is Gore's Advanced Road Women's Seat. There is plenty of soft padding that keeps you comfortable for long rides – after four hours I was still happy with it. It's tapered down towards the edges so that it doesn't feel or appear too bulky. I didn't experience any discomfort whatsoever with the pad throughout testing. The insert is made with Gore's Cup Technology too – it certainly keeps the lower torso and hip area toasty warm without causing you to sweat excessively.

Comparing the price against other tights with 'pee-stop access systems' isn't too difficult as there aren't many out there. Sarah liked the Funkier Thermesse S-980W C12 Ladies Winter Single Strap Tights, which are now £79.99. She also really rated the previously mentioned dhb Aeron FLT Women's Roubaix Halterneck Tights, which cost £85 at rrp (currently £49.99). Compared with these, the Thermo Bib Tights+ are a little expensive, but Gore's great reputation for quality, high-performing kit might convince you they are worth the investment.

Emma’s first encounters with a road bike were in between swimming and running. Soon after competing for GB in the World Age Group Triathlon Championships in Edmonton in 2001 she saw the light and decided to focus on cycling. 

After a couple of half decent UK road seasons racing for Leisure Lakes, she went out to Belgium to sample the racing there and spent two years with Lotto-Belisol Ladies team, racing alongside the likes of Sara Carrigan, Grace Verbeke, Rochelle Gilmore and Lizzie Deignan. Emma moved from Lotto-Belisol to Dutch team Redsun, then a new Belgian team of primarily developing riders, where there was less pressure, an opportunity to share her experience and help build a whole new team; a nice way to spend her final years of professional racing. 

Since retiring Emma has returned to teaching. When not coercing kids to do maths, she is invariably out on two wheels. In addition to the daily commute, Emma still enjoys getting out on her road bike and having her legs ripped off on the local club rides and chain gangs. She has also developed an addiction to touring, with destinations including Iceland, Georgia and Albania, to mention just a few. There have also been rare sightings of Emma off-road on a mountain bike…
