I have some Go Outdoors vouchers to use and I think I want one of these, but I’m unsure on which one to get.
It will be used for when I’m walking as opposed by biking.
I notice a few people use Montane Flux/Prism even for biking – would they be too warm for high-energy activities like biking?
GO are doing a Rab Generator Alpine for £100 at the mo – might get my arse down there and try a few on.
£100 would be my limit.

Any tips?

They are too warm for active use. If that’s what you want it for, check out the Rab Strata stuff. Not quite as warm as PrimaLoft and similar, but way more breathable. Most synthetic-filled jackets are a sandwich of two windproof fabrics with filling in between, effective you’re wearing two wind proofs with an air-gap between them, not good for staying dry and comfortable unless you run really cool.

Very good as belaying jackets slipped on over your goretex as they don’t spoil when it rains but do keep you warm while your second is making a meal of it.

As above, normally too warm for biking unless it’s -10 and it’s something like a buffalo shirt worn against the skin.

Make sure you get something with a comfortable fit, some of them have weird fits that I find too restrictive for leaning forward on the bike in.

Mrs Simmo here: I have a Rab Strata hoodie and previously had a north face redpoint jacket. The north face is definitely warmer and I was worried the Rab wouldn’t be warm enough (it’s fine actually) but the redpoint’s lack of hood was impractical for walking to work as I still needed a waterproof as well. I find the Rab jacket about right for walking in (I’m a fast walker so heat up quick and cover 3-5 miles/day), it’s water resistant enough for me not to have to take a waterproof as well on all but the wettest days. I’d use it for proper walking too as it’s very light and you could layer up well to add warmth.

The Flux in moroccan blue looks shit* online. Its darker in person and boythe Flux is now my default run outside, 6am shop walk, bike assemble at the side of the road at 7.40am in winter, walk to get beer in winter at 10pm, emergency boot jacket etc etc etc all in a tshirt so far. In minus it’ll be +Icebreaker.

*Black or steel in person looks like a bin bag. The moroccan blue Prism in person looks loud – weird.

No bloody Generators in my size (only small) but the Montane Flux was really nice.
Does anyone use one of these for non-bikey activities?

I;ve got a Prism which is ace and lots of colleagues (outdoor pursuits) use the Flux

The black flux does look a bit bin baggish (I have one) but it is warm and quite waterproof.

rtg – Do you find you can use your usual layering system with it? I use a baselayer with a Windstopper softshell (dry) or Paclite (wet) and a Berghaus thin gilet if it’s cold.
Is it something you walk in or something you get out of the rucksack when you’ve stopped – that’s when I get really cold…having an all-over warmth would be better than my gilet.
I notice the Flux has more features/pockets etc than the Prism – do you find the Prism good in spite of that?

So many questions…. 😉

I usually wear it over a baselayer and maybe a microfleece. Because its less insulated than the Flux I actually find it more versatile- I wore mine almost non-stop the first year I had it. Three/four years down the line its a bit tired, but still useful.

I bought a Karrimor avalanche from Field&Trek before xmas down to £55 from £150 been very pleased so far, quality is excellent, considering I was expecting to spend £200+ this is a bargain

In true STW style, here’s an answer you didn’t ask for! I wanted a warm jacket: I’ve got a few thinish jackets, hardshell, softshell, windshirt. I recently bought a synth gilet which I wear a lot of the time now, on it’s own or with one of the others.

Fantastic, and great on the bike, keeps your core warm and if you wear it on top, it’s really easy to ditch heat if you do get a bit warm just by unzipping a bit or most of the front. – you’ve barely got it on then.

I got this one £50 in a sale. http://www.e-outdoor.co.uk/441089/products/arcteryx_mens_atom_lt_vest.aspx?origin=pla?kwd=&gclid=CK6F_-2E57sCFY3LtAodcAsAVw

Although browsing the g-o site, I found this which had me tempted for a while when I was looking:

Rab Exodus is worth a look or anything with a double weave stitch.

Granted its not as windproof as say Primaloft but it has better ventilation.

I bike and fell walk in mine and its fine however it can get a bit chilly if hanging around on exposed summits if you’ve only a single layer underneath.

For what its worth I found Montane rather short in the body. The arms on rhe Rab are long whichbis a good thing whenntour stretched out over a bike.

I have an older version of the Rab Exodus jacket. It’s a brilliant jacket, but too warm for doing anything active in. I take it with me on a lot of rides or walks in winter as a backup if something goes wrong or for hanging about in. One of my favourite bits of clothing though. I also have a very lightweight primaloft jacket that has less insulation, but as someone pointed out above it’s like wearing two windproof layers so it can even get a bit sweaty even though it’s not as warm as the Rab.
