Very Warm

Extremely warm enabling less layers to be worn. Only downside is that it seems to be wearing out quicker than I was expecting

Toasty and comfortable

These things are fantastic

I am amazed at how warm these are. Been out for a couple of hours in 2degrees and not felt the cold ( wearing them under Alpine Stars drystar 2)
I’ve got the top as well. I’ve seen reviews where people say they are scratchy or uncomfortable. I don’t find this at all.
I thoroughly recommend this product.

Size matters
27 Jan 2026 by Anonymous
A good quality product, warm and great under leathers. The sizing lets this product down. I’m a large and purchased large, first impression they felt great. After use the legs ride up, too short and the seat rides down, the leggings need more length in the leg and room in the seat and a higher waste.
Probably, on balance should have tried XL

Excellent gear

Bought this alongside the top. As with the top friends said this might be itchy but it isn't at all. Very comfortable and good fit with 30 inch waist and 30 inside leg. Does the job well. Would definitely recommend.

Does the job but no choice for woman

It’s pretty warm but it’s only male version and it’s noticeable under leggings. Looks embarrassing in certain area.

Probably the best

Despite some reviews saying they’re scratchy or irritating on the inside, I found them very comfortable. Not so sure about the “heat rub” effect being relevant on a motorcycle, but they are the warmest leggings In the wardrobe. Not five stars due to the cost.

Warm when it's cold yet still comfortable when it
26 Oct 2025 by Pat B
I bought these for a trip to France at the end of September, knowing that I would have to leave in the early hours of the morning for a 2.5-hour ride down to Dover. Despite the overnight temperatures being chilly, 8-10 degrees C IIRC, my legs remained comfortable only wearing single-layer jeans over the top. Once in France, the temperatures rose to the mid-teens, but I didn't feel too hot. They do an amazing job of keeping you warm whilst breathing well, so you don't overheat when it gets moderately warm. They are also very comfortable.

Good quality

After purchasing these previously, my partner wanted more of them before winter. Nice and thin, as used by Glen Irwin, keeps you warm but giant bulk you out.

Wasn't sure about all the hype regarding Zerofit, but i can confirm it does truly work, you definitely can feel the warmth coming through, especially when you start moving about on and off the bike. I would recommend for sure. Great quality and a good fit to without been overtight. I will be using these under my jeans on cold winters day when not biking also!

Description
The Heatrub technology, engineered in Zerofit's Japanese homeland, uses 'double-loop' barrel fabric which provides both heat insulation and 'friction heating'. The extra-long heat threads ensure a layer of warm air is retained around your legs and even just a little movement of these bristles causes friction which creates cosy warmth.
