Rab Zephyr

I bought a Boreas and immediately sold it. Fit was weird (tight across the chest and loose in the hips) and the fabric was too plasticky/rubbery for my liking. I bought an Alpine Jacket instead and love it, although not for bush bashing (as we say down here) and not under pack straps for too long.

The Zephyr looks like a better fit, but is the fabric still that kind of gross, too-much-elastane style? I assume you like the Zephyr over the Alpine because it's more durable?

Looks pretty cool, but out of curiosity David, what exactly is the intended usage of this jacket? It seems somewhere between a fleece and a windshirt. Would a windshirt and fleece not do the same job with more versatility? Perhaps the zephyr is a lot more durable than a windshirt's face fabric.

Also how much insulation would you say it provides. Is is comparable to say an r1 fleece?

It appears to be like the Boreas, it's a breathable windshirt. The point of it is to be as windproof as it can be (not trying to be entirely windproof) without compromising breathability. It seems a soft shell fabric (Matrix) filled the niche. Oh and it's UVP with anti-odour.

For the windiest English spring in memory my Boreas been de facto windproof and way more breathable than my Cirrus. Insulation is more like a heavy tee shirt than a fleece.

A fleece + Pertex windshirt doesn't do the same thing. That's English winter gear.

If you didn't like the Boreas fabric, I doubt the Zephyr would be any different.

I sold my Alpine mainly because durability was a concern. In theory it works great, but in practice I found myself wanting either more wind protection (i.e. a Cirrus/Houdini/etc) or more breathability (i.e. Boreas). In the end we're splitting hairs w/r/t performance differences so folks should take this with a grain of salt. Individual variations in preference and metabolism will make a bigger difference than "inherent" performance differences in fabrics.

As I've written far too often, the Boreas and comparable garments are more breathable versions of classic lightweight windshirts. They seem to offer a bit more tear resistance as well. The cost is the heavier fabric, and especially the slower dry time. I've found the Boreas fabric suits me more often than anything else, which makes packing simpler.

Edit: I'd put the static warmth of the Boreas fabric on par with a midwieght (~150 g/meter) synthetic baselayer. The wind resistance will up the felt warmth in many circumstances.

I've worn the Zephyr on every trip I've taken in the last month. For early summer alpine stuff, where warm sun alternates with cold wind minute to minute, it's perfect (for me).

The better fit of the arms and hood are very much appreciated. The addition of a factory DWR on the arm/shoulder fabric extends the usability in rain a bit, and doesn't seem to make it any warmer or less breathable. The thumb loops are well executed. The main zip runs smoothly and well. I have the mineral color and like the light option as its a bit cooler in the sun.

The side pockets need to be just a hair higher to clear hipbelts. The zippers are fine, but the combination of small guage and the stretchy fabric makes them run not so smoothly.

I notice no value in the anti-stink treatment. The Zephyr smells about as much as the Boreas after a few days continuous use.

One odd aspect of the Boreas that I like is that, unlike a wind shirt, it compresses the billowing, flapping, whipping, and air-pumping out of my RailRiders BoneFlats sun shirt. I like that billowing when it’s sweltering hot, but I hate it early in the morning when it’s freezing. The Boreas hood turns my cool OR sun hat into a solid blob of nylon that actually adds warmth to my head.
