BTwin Ultralight Bike Gilet 700
9 10

B'Twin's 700 Ultralight Gilet is my favourite bit of kit at the moment. It comes with me on virtually every ride thanks to its light weight and packability.

Ultralight is bang on as you can barely feel this gilet when it's in your hands let alone on your back. The 100% polyester fabric is very thin which keeps the weight down to just 60g for the large size. It's fully windproof and does offer a degree of water resistance against drizzle and fog.

You don't get a mesh back to disperse heat like you see on a lot of gilets but there are two armpit vents which do a pretty good job of stopping you getting too clammy.

The cut is pretty form fitting with no excess fabric flapping about in the wind. An elastic hem keeps things in place when you're on the bike. It's got a good high neck too. The full length zip is covered by a small tab to stop neck irritation.

At the rear is a neat little drawstring pocket which'll hold a phone and an energy bar. On the other hand you can stuff the gilet into it when you've finished wearing it. You can be pretty rough with the Ultralight when ramming it in there making it easier to put away while in the saddle. The whole package ends up the size of your palm and easily fits into a jersey pocket.

White is the only option but its very tastefully done with just a few small logos dotted around. Road spray washes off fine and I didn't have any issues with staining over the test period.

In use the Ultralight is amazing at keeping the wind out for such a thin fabric and the wind on your arms is more noticeable due to the fact that the BTwin is blocking it completely from your torso. The neck keeps the drafts out to front and back.

It's comfortable, moving with you well on the bike although you do get that scrunching noise that afflicts all polyester items and a large amount of static which thankfully is more noticeable when you are putting the gilet on or off.

Overall

For a penny under twenty quid the Ultralight is pretty amazing. Not only does it perform well and look smart but BTwin back it all up with a two year warranty. Looking at the construction though I don't think you're going to need it.

Verdict

Smart looking, great performing stowaway gilet that's hard to beat in terms of value for money

Stu knocked out his first road.cc review back in 2009 and since then he's chucked the best part of seventy test bikes around the West Country, a couple of them quite literally! With three alloy and two steel bikes in his fleet he's definitely a metal man (that'll be the engineering background) but is slowly warming to that modern carbon fibre stuff along with fat tyres & disc brakes.
It's not all nostalgia though, after spending the last few years in product design Stu keeps banging on about how 3D printing is going to be the next big thing and he's a sucker for a beautiful paint job too.

Having finished my last couple of rides with the sleeves on my current windproof rolled up, the timing of this review is pretty much spot on! Looks decent value too, but then BTwin stuff almost always is.

I like the fact that there's a bit of a love affair between Decathlon and Road.CC at the minute; they're the only ones reviewing Btwin/Aptonia, and all products invariably com back with a decent rating, echoing the experiences of many budget-conscious cyclist.

Cycling as a hobby is bloody expensive; Decathlon should be applauded for cutting prices and not quality.

(My tuppenceworth; Aptonia gels are the best I've used, Btwin series 7/9 kit is as good as anything on the market).

Good to see this review, I was in Decathlon Stockport last week driving away thinking I wish I'd bought one as I had a very damp drizzly ride out last Sunday, this would have been ideal addition to the not-so-fair-weather kit.

I feel sometimes that Decathlon is viewed as the Aldi/Lidl/Skoda of the cycling world (some people just wouldn't be seen dead with their products). I have always liked their stuff for its value for money - having discovered Decathlon in France while on holiday years ago. As a family of keen cyclists and walkers, just about every bit of kit we own comes from Decathlon.
Many thanks to roadcc for this slight change of direction towards more budget products making cycling more inclusive rather than exclusive  4

No shame in decathlon, they do a whole range of stuff from budget to high performance and none of it is crap.

I'm a bit of a badge snob though, so I will admit to not having many of their jerseys....
