The result is a windproof and highly weather-resistant fleece that works well not just as a midlayer but also as a warm outer layer in chilly, gusty and drizzly weather. It’d be well suited to weekend walks from spring through to autumn, but perhaps not – despite the name – the ideal piece of outerwear in an actual blizzard.

The Blizzard is basically a membraned ‘hard face’ fleece, which ensures it is windproof and water repellent. But it’s also warm and reasonably breathable too, as well as being soft and comfortable thanks to a brushed inner lining. Pit zips under the arms also help you to dump heat fast.

On the outside of the jacket, the shoulders and lower sleeves are reinforced with an extra-robust 500-denier Oxford polyamide (nylon) fabric, which should be very resistant to abrasion from pack straps as well as general wear and tear. Unusually, the jacket is also equipped with a rollaway lightweight hood that stows neatly in the jacket collar. Other features include 2 hand pockets, a chest pocket and an inner pocket as well as an adjustable hem.

Berghaus Spitzer Hooded Fleece Jacket

Price: £70
Weight: 393g

The Spitzer Hooded Fleece Jacket from Berghaus bridges the gap between a traditional fleece and something slightly more technical. With this, Berghaus claim that they’ve made a midlayer that’s designed for the coolest climates. Whilst we wouldn’t agree that this is the warmest in this roundup, Berghaus has certainly achieved an impressive amount of warmth for its weight.

The outer of the Spitzer consists of a tighter and denser weave compared to many of the other more lightweight offerings in this roundup. This not only gives the fleece a simple, traditional look, but also slightly improves wind resistance.

You’ve got a pair of handwarmer pockets on the Spitzer, which are nicely lined with a soft material to warm your digits whilst you’re keeping them tucked away from the elements. There’s also a basic hood that will fit comfortably underneath a helmet.

Berghaus’s description that this fleece is ‘cut for comfort’ is spot on. I found the Spitzer offered a much roomier fit than some of the other fleeces in the roundup. That’s not to say it’s too baggy, and it’s by no means a complaint. I sometimes appreciate having a fleece that doesn’t feel like some sort of lycra catsuit, particularly when popping down to the pub for the post climb/walk beers.

Full Specification

S – XXL / two neat hand pockets /  close-fitting hood / 90% bluesign approved fabrics / under helmet hood.

Arc’teryx Proton FL Hoody

Price: £200
Weight: 320g

All new from Arc’teryx for 2019. This midlayer admittedly blurs the line between fleece and fill insulation with the use of Arc’teryx’s extremely lightweight and breathable Octa Loft fill. Still, we’ve included the Proton into this fleece round-up rather than our best insulator round-up due to the amazing levels of breathability it offers. I felt like I was able to keep consistently moving fast through the mountains whilst this kept shifting moisture away from my body when worn next to a baselayer.

Arc’teryx have managed to achieve this impressive amount of breathability by pairing the insulation with a highly porous, yet lightly wind resistant Fortius Air outer fabric. This outer shell is also DWR treated, so as long as you care for the fabric, it will keep off light rain/snow showers.

The Proton reminds me of a lighter weight and more technical version of my old Rab Vapour-Rise Jacket, a jacket that I practically lived in during the years I spent skiing and climbing in Scotland. That was a good midlayer, and this one is even better.

A notable moment using the Proton was whilst I was ski touring in the Alps at a fairly high pace (around 70% heart rate range) over a constant period. I stopped at the top of a hill and realised that I hadn’t  felt the need to unzip it to let any hot air escape at any point during the ascent.

All of this breathability and wind-proofing is paired with a fairly athletic fit and a slightly dropped back, with a low profile hood that will fit under a helmet. Whilst this jacket has been stripped down on weight, it still boasts four great outer pockets; two on the chest and two on the hip.

Full Specification

S – XXL / The Fortius Air 20 fabric / Octa Loft breathable insulation /  low profile, fitted, adjustable under helmet hood / two zippered chest pockets / two zippered hand warmer pockets.

Columbia Drammen Point Fleece

Price: £65
Weight: NA

You can certainly tell Columbia’s American heritage with this fleece – ‘roomy’ is the best description regarding the fit. However, if you size the fleece correctly, based on the generous fit, you’ve got a great fleece that can do it all. It’s comfortable, breathable and warm and simply does its job well. Smaller details include a single chest pocket, handwarmer pockets, and elasticated cuffs on the sleeves and hood. There’s also a nice, smooth weave used for the outer material which, while feeling nice to the touch, also helps with the overall aesthetic – it’s another one of those ‘on-and-off-the-hill’ midlayers.

Overall, we felt that the Drammen Point Fleece was a worthwhile contender in this round-up mainly due to its low price and decent warmth-to-weight ratio.

Full Specification

S – XXL /  front zip / zippered chest pocket / zippered hand pockets / under helmet hood.

Mammut Aconcagua Pro

Price: £169
Weight: 433g

The Aconcagua fleece from Swiss manufacturer Mammut utilises two fleece materials strategically designed to help your body manage its climate effectively. In short, the name of the game here is top-level temperature regulation.

It uses Polartec’s now classic Power Stretch Pro fabric, an ingredient that has become a mainstay in the midlayer market. Work hard and this stuff breathes with you. That’s especially thanks to the added bonus of having Pontetorto Technostretch panels on the sides and on the back – those places where your body is going to be trying to expel air the most.

The Aconcagua has also been designed with a classically European slim fit. I found this to be the closest fitting of all the fleeces that I tested in this roundup, so I’d suggest to size up if you usually prefer a more traditional fit.

Full Specification

S – XXL / YKK Vislon front zip / elastic Pontetorto Tecnostretch on back, under arms, hips and hood / Pontetorto Tecnostretch waffle structure on inside / Polartec Power Stretch Pro / under helmet hood.

Rab Alpha Flash Jacket

Price: £100
Weight: 273g

The first thing that you’ll notice when you pick the Flash Jacket up, is the weight (or lack of). At just 273g and packing a fair bit of warmth, Rab have introduced a few nifty features and fabrics to the classic fleece design.

First and foremost, they’ve used Polartec’s Alpha Direct fabric. If you’re not yet familiar with this, it’s rather extraordinary stuff. It has a very traditional feel, almost like pile fleece, but there’s way more to it than that. The temperature regulation it provides is truly excellent, and then there’s the warmth-to-weight. If you hold this up to a light, you can really see how thin the Polartec Alpha Direct fabric is, but then there’s also that lovely warm and cosy feel to it.

Stretch panels flank the sides of the fleece to further improve breathability and ensure there’s no restriction of you’re movement when you’re reaching upwards for a hold or at full stride while running. There’s also that useful zipped pocket for stashing away, say, your phone or GPS.

The one slight niggle that I had with the Alpha Flash Jacket was that it seemed to have excess fabric around the wrists, just before the cuff elastic pulls it all in. That’s it though.

Full Specification

S – XXL / Polartec Alpha 178g m² / Polartec Alpha Direct 120 insulation / Polygiene Stays Fresh Technology / slim fit / Half hem drawcord.

Alpkit Griffon

Price: £49.99
Weight: 325g

Another extremely lightweight fleece, the Griffon by Alpkit utilises a similar (but lower bulk) grid design to Polartec’s Power Air. This pattern creates pockets of warmth while also expelling any sweat vapour through small channels.

Alpkit have designed the Griffon with a close-to-skin fit, which means that it can also be used as a warm base layer, if you don’t mind the feeling of a full length zip next to your skin.

At only 250g and with a £40 price tag, this is a hard to beat fleece with great value for money. Whilst it’s never going to be as warm as many of the other fleeces in this roundup, it will make a great summertime companion.

Full Specification

S – XXL / Alpkit’s 3 year alpine bond / full length Vislon zip / snug fitting lycra bound hood / external chest zip for valuables / two-tone smooth face.

Adidas Terrex Polartec Power Air

Price: £160
Weight: 700g

When you first take a look at the Adidas Terrex Polartec Power Air, you may think that it’s just a stripped down, basic midlayer. However, during use, I was surprised to find out that it has some handy features to make life in the mountains that little bit more comfortable.

The first thing worth noting about this is that Adidas splits each size (S, M, L etc) into two separate chest measurements. This is actually really handy when it comes to your overall layering system as it gives you the choice of either having something loose enough that you can wear over other layers or something close enough to fit underneath a layer or two.

The new Polartec Power Air fabric is an evolution of their previous Power Grid fabric that was used, for example, in the Patagonia R1. It features the same waffle-like grid pattern of fleece with hundreds of little pockets that trap warm air while expelling any moisture-heavy vapour, but now it’s much, much hardier and no longer sheds any of its microfibres.

 In an aesthetic sense that’s good of course, but it’s also pretty important if you’re thinking about longevity. Essentially, this new development means the fabric will last much longer.

Two handwarmer pockets are included, but I wish Terrex had added in a single chest pocket as I always like storing my phone there so that my body heat will help to preserve the battery. Still, there’s a very small left arm pocket, which looks likely to be designed to carry lift passes for ski or alpine walking/climbing use.

I loved taking out and using this fleece. I found that although the size I tried had a fairly close fit all-round, it was able to stretch and move with me when ski touring and hiking and it offered fantastic breathability. It’s going to become a great partner for me to take on climbing trips, where the long sleeves and elastic cuffs will avoid any cold spots forming when reaching high.

Full Specification

XS – XL, with S/M options within each size / zip sleeve pocket / side zip pockets / full length zip / visor on hood / Polartec Power Air / high neckline / long sleeves.

Houdini Power Air Houdi

Price: £180
Weight: 706g

Houdini are known for creating clean looking, sustainable clothing and the Swedish company continue this trend with their Powder Air Houdi.

At 706g, this is another heavyweight fleece that, like the Adidas Terrex fleece above, utilises Polartec’s new Power Air fabric. If you haven’t already, just read that review to hear about the benefits of this material.

As well as using the same Polartec fabric as the Terrex jacket, it’s also designed in a remarkably similar way. You have to get up close to the two fleeces to see the differences. The use of a two-way zipper on the full length zip, thumb loops and a hidden draw cord mark the differences between the two.

Full Specification

XS – XXL / high collar hood / Bluesign certified fabric / full length zip / visor on hood / Polartec Power Air / high collar hood.
