dhb Aeron Rain Defence Bib Shorts
9 10

The dhb Aeron Rain Defence Bib Shorts are an excellent pair of bibs for chilly days. The 'Rain Defence' just adds to a well fitting and comfortable pair of shorts. Rain can make riding miserable. Lycra is near to useless in cold rain so I was pleasantly surprised to find that my legs didn't freeze to useless lumps when the rain came down.

The shorts are also very well proportioned, with comfy bibs, and the pad is also excellent. While riding I experienced no bunching of material and the dense pad stayed just where it should.

Firstly, it should be noted that the name 'Rain Defence' means it will repel all but the heaviest and prolonged spells of rain. Rain will eventually get through but it will take a good deal longer than conventional Lycra, and what gets through will be significantly reduced. dhb has also used minimal stitching to help the waterproofing. This keeps your big working muscles dryer and warmer for longer. I found that rather pleasant on the chilly morning commute, especially when the heavens opened unexpectedly.

The cut is quite race orientated, coming from dhb's 'performance' fit. I found that the bib straps were tight over my shoulders when standing up, but perfectly supportive when in a riding position.

The Lycra on the legs is supportive yet not restricting, and I found that this stopped any snagging on the saddle. The legs are finished with minimal leg grippers, but because of the excellent fit, there was no upwards movement.

dhb has specced the CyTech Comp HP chamois, which features dense padding for long ride comfort. There is also an anti-bacterial cover, which I found comfortable for rides over four hours.

Aesthetically, the all-black design means that the shorts stay looking new for a long time. The minimal branding is also a subtle touch from dhb, meaning that the shorts will complement any jersey.

Verdict

They fit perfectly and do what they claim very well too – at half the price of many, these are a real winner

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

Really well, in terms of rain-repelling and comfort.

Tell us what you particularly liked about the product

The water just runs off. That and the styling is reserved so these will go with all your other kit.

Tell us what you particularly disliked about the product

If I'm being ridiculously picky, the thickness of the material meant that when the sun shone, they got a little warm. Not going to have that problem many times though.

Did you enjoy using the product? Yes

Would you consider buying the product? Yes

Would you recommend the product to a friend? Yes

Use this box to explain your score

Only let down by the fact that tumble drying will take away the rain defence. The rest is excellent quality for good value.

Overall rating: 9/10

No. It's a close-weave fabric with a DWR coating.

This looks a fantastic move from DHB. Plain black, functionally excellent, bibs. I'll be picking up a pair to try this winter. Had a (not water resistant) pair from them a few years back which aside from the colouring scheme have been excellent. Always my first choice for an indoor trainer session.

Any recommendations which size I should go for? I am medium in Castelli bibs and between a small and medium in Rapha bibs.

I don't know. The info page says "Waterproof Fabric ".

I have the Giordana G-Shield bib tights which just have a DWR coating. They protect you if you spill your Coke on your leg... but they are useless against rain, even when new.

I can't speak for these specific shorts but I'm a medium in both DHB and Rapha. The shorts seem to fit the same, the jerseys a touch tighter in Rapha.

 

I have used the rain defence leg warmers on the Tour Divide and they were pretty good. I used Gore shorts and the leg warmers instead of waterproof trousers) the rear panels did eventually let mud work its way through them.

I'd suggest the medium. I go for the extra small in dhb's basic bib shorts and that gives a tight fit. I've loved having a slightly more relaxed fit.
