Santini Vega Xtreme jacket - riding.jpg

While here in the West Country we've mostly had quite a mild autumn there have been frosty cold days to put this cold weather jacket through its paces. In that time, the Vega Xtreme proven to be a technically-adept cold weather jacket, with a marginally stronger leaning towards the frigid conditions than on wetter weather.

Lined by fleece technology from Polartec on the inside, and the brand's Windbloc membrane construction on the outside, it's claimed to work optimally in the -8-+5 degree range, and it absolutely does.

Santini Vega Xtreme jacket - Polartec.jpg

This is one warm winter jacket, which works first and foremost by completely blocking cutting winds on the outside, and adding toastiness and comfort on the inside courtesy of a thermal layer next to the skin. Naturally, when mild day temperatures begin to hit – approaching high single figures, according to my Garmin – things can get a little too warm, but you can't have everything.

The fact is that it breathes very well in the temperatures that it's designed to work in, and I found myself perfectly happy riding in it with just a merino base layer on underneath. The base layer itself was damp after a 40km tempo spin in 2-3 degrees, but then again its job is to pass moisture away from the skin, in the process taking it on itself, so I'd expect this anyway.

The jacket sizes about normally with a slim fit in a medium, while if you ride in an aggressive position there's enough length in the arms and back to do so without it riding up. I like a form fitting winter jacket that isn't restrictive at the same time, and the Vega Xtreme fits the bill perfectly.

The underarms are less thick than the rest of the body with a mesh-like outer to help a bit with ventilation, while the jacket's cut is designed to create that protective shell that you want when things are bitterly cold. Especially, I liked the high collar with Polartec's Alpha fabric (a fluffy kind of textile) which works like a comfort blanket – effectively removing the need to wear a gaiter in the process – and the neoprene cuffs that create a comfortable leak-less seal.

The same absolutely waterproof thin neoprene outer is used on the substantially dropped tail too, as well as over the central zipped cargo pocket for piece of mind when road spray and showers are the order of the day. You also get the same material behind the zip to keep out both draughts and water, and Santini has thought that you'll more than likely be wearing gloves with the jacket, so has included a large metal puller for the zipper itself for ease of use.

The main fabric is water resistant enough for repeatedly showery weather – just about on a par with Castelli's Alpha RoS jacket which uses Gore's Windstopper 150 material – but the neoprene parts do offer that extra bit of coverage in strategic areas that the Alpha RoS can't match. Swings and roundabouts, really. (As a side note Castelli also produce a women's version of the Alpha Ros there is no female version of the Vega Xtreme).

This is a one-piece construction too, which simply for the avoidance of faff when dressing/undressing/washing is a positive in my view, and you'd hope that'll have long term benefits in terms of how long the jacket lasts. More seams means more to go wrong in my view, no matter how good they are, so a simpler construction in what's supposed to be a tough outer layer seems like a good idea to me.

Nevertheless, it's not flawless in this regard. It might have a great fabric construction throughout, but one of the silver rings that line the drainage holes in each of the flanking pockets popped out before I'd even worn the jacket. I hope that this is an isolated incident and it hasn't affected the effectiveness of the garment, but it's a shame that it's happened, and I'll update this review if it does show more failings in the coming deep winter season.

There are also a few high-visibility features in the left shoulder tab that also has some reflective dots, and in the Santini branding over the dropped tail and around the base of the elasticated waist. However, some might see the general plainness as a bit of a downside. I don't personally – I ride with lights on my bike in the winter when the sun's not out – but some may prefer a brighter option.

Naturally it requires a little care to maintain the effectiveness of the moisture wicking and water-resistant properties of the fabric, but Santini recommends a 'normal' 30 degree wash. You can do that if you wish, but with technical garments like this I always like to err on the safe side by using a technical wash if I can – when you're spending £210, you want to know that it's going to work for a few winter seasons at least.

Still, that's £65 less than Castelli's Alpha RoS, which ostensibly does the same job and does it equally well... but not markedly better. Now, there's a tribe of Castelli-lovers out there who will still be swayed by the Alpha RoS and that scorpion logo, but if you're not sure which to plump for and simply want the best jacket for the money, then the Vega Xtreme is the winner.

Rate the jacket for quality of construction:
 
7/10

The seams and fabric seems very well constructed, although the silver drainage hole ring popped off before I even used the jacket. It seems an isolated incident, though. Loses a mark here for that though

Rate the jacket for performance:
 
10/10

In cold weather where showers are around and a constant danger, it's fantastic.

Rate the jacket for durability:
 
8/10

The Polartec fabric is certainly hardy, as are the neoprene sections in the right places.

Rate the jacket for waterproofing based on the manufacturer's rating:
 
9/10

Very good, and absolutely what you need from a tough winter outer layer.

Rate the jacket for breathability based on the manufacturer's rating:
 
8/10

Breathability is good if you wear it in the very low temperatures that it's designed for. If you don't, you do end up sweating a fair amount.

Rate the jacket for fit:
 
8/10

It's certainly designed as an outer layer so there's space, but in a medium it's slim without feeling too tight anywhere.

Rate the jacket for sizing:
 
9/10

Sizes about right to me for an outer layer.

Rate the jacket for weight:
 
7/10

At nearly 400g, it's certainly on the chunky side, but in cold and harsh winter weather a little weight can be welcome I think - it's a 100g less than the Alpha RoS too.

Rate the jacket for comfort:
 
9/10

I personally found it very comfortable, especially with the thermal lining and 'Alpha' collar.

Rate the jacket for value:
 
8/10

It does pretty much it all, and at £210 that can't be a bad thing.

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

Very easy given that Santini says you can just wash it with normal detergent, but I choose to use a tech wash just to keep things tip top.

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

Extremely well indeed.

Tell us what you particularly liked about the jacket

Very warm, perfect performance fit, good water resistance.

Tell us what you particularly disliked about the jacket

One instance of build quality.

How does the price compare to that of similar products in the market including ones recently tested on road.cc?

Compare it to the similarly tasked and very, very good Castelli Alpha RoS jacket https://road.cc/content/review/251187-castelli-alpha-ros-jacket, and it looks great value at £65 less.

Did you enjoy using the jacket? Yes.

Would you consider buying the jacket? Yes, it's a real rival for the Alpha RoS.

Would you recommend the jacket to a friend? Yes, I'd have to with this performance and at this price.

Use this box to explain your overall score

I gave the Castelli Alpha RoS jacket 9/10, and this comes perilously close to claiming a coveted 10. However, that small issue with build quality knocks off a mark, and its bulk might put one or two off.

Overall rating: 9/10

I own this jacket, purchased it for a bit less than the 210 GBP (introductory offer) and by and large I agree with the review, only 2 remarks:

 

- When riding to work this morning, into a headwind with prodigious quantities of sleet and snow coming down, I noticed that there's an achilles heel:  the area under the arms.  On a road bike (and on what else would you be wearing this?) the water/melting snow gets driven to the back by wind pressure.  Presumably to help ventilation, the fabric under the arms is different/lighter, and some water did make it through, enough that I was aware of it while riding.  The rest of the jacket is absolutely water- and windproof.

- I wear a sports watch (Garmin fenix 5X plus) and while I can put on the jacket just fine, taking it off requires removing the watch first, else the neoprene cuff snatches on it.

For the rest nothing but praise, no rivets popping out like the reviewer mentioned  and the jacket really is warm:  I've been riding to work and back home in temperatures between -3 and  +6 centigrade wearing just a 260 weight merino baselayer under it and I was just fine.  Below -3 and I do believe you'd need to wear something extra.  It does breathe, not like GoreTex Shakedry but enough that you won't feel like a bagged chicken.

Oh yes, it dries quickly.  Hang it to dry and after one hour you're set and ready.

 

Guess I'd rate it a 3.5 to 4 out of  5, taking into account the price.  But overall I'm happy with it.
