Ibex Icefall Jacket and Glacier Vest

Print Jump to Reader Comments

by the Product Review Staff | 2003-07-02 03:00:00-06

Both the Icefall and Glacier use Ibex’ Climawool™ Lite, which is similar to Schoeller Dynamic. It has a woven shell of Nylon and Lycra but has a napped merino wool lining. Climawool™ Lite is an upgrade to Schoeller’s Skifans fabric (Ibex had Schoeller modify Skifans to be more resistant to pilling). We found this fabric to be a good blend of warmth, breathability, and wind and water resistance. The napped merino wool lining increases the warmth, moisture management and comfort range of the fabric over standard Dynamic fabrics.

Icefall Jacket

The Ibex Icefall Jacket is a simple stretchwoven, full zip softshell. It has two mesh lined hand warmer pockets, and a one-hand-operated waist drawcord. The only two "extras" are a nice napoleon pocket and a soft merino wool lining (a side benefit of this is a soft collar). In typical stretchwoven style, the jacket has a fairly trim fit but we found it to be a little roomier than competing all-synthetic garments from Cloudveil and Arc'Teryx. The sleeves are generously long and you have full range of motions without restriction or the waist lifting. The jacket has room for a couple of base layers or even a light insulating layer. We’ve used the Icefall jacket extensively for ice climbing, skiing, snow shoeing, and all other manner of cold weather aerobic pursuits. The jacket weighs about 16.5 ounces.

The Icefall jacket's wool lining separates it from the rest of the stretchwoven crowd. At only 1.5 ounces lighter than Cloudveil's Serendipity (the gold standard of softshell jackets), the Icefall is less wind and water resistant, but has a wider comfort range across the temperature spectrum than the Serendipity. It is similar in weight to Cloudveil's Veiled Peak jacket, but we felt the Icefall offered more performance and comfort with the addition of wool.

One key benefit of the Icefall: after several continuous days of skiing, climbing, and sweating in it and not washing it, it resisted odor very well, when we couldn't wait to get home to throw our all-synthetic stretchwovens in the wash under similar conditions.

Glacier Vest

The Glacier Vest loses the arms to come in at under 9 ounces. At twice the weight of a thin wind vest and a few ounces heavier than a 100-weight fleece vest, we were eyeing it with scrutiny in order to discover a potential market niche. Its Climawool™ Lite fabric it is warmer, more abrasion resistant, and more water resistant than thin nylon wovens found on other wind vests. The fabric is more wind-resistant than 100-weight fleece but not quite as warm when worn under a shell. The Glacier is more breathable and more suited for aerobic activity than either a thin wind vest or a fleece vest. Its smooth surface allows it to layer under other garments more effectively than fleece. Vest features include two hand warmer pockets, two large internal storage pockets, and a draw cord waist.

During months of testing, we discovered that the Glacier offers a niche that is not quite filled by any other garments on the market. We wore it in windy summer-and-fall alpine hiking conditions, where temperatures were cool enough to require something over our base layers, and windy enough that we wanted some wind protection. The arm freedom of the vest design provided both insulation and wind resistance without sacrificing breathability or freedom of movement. For these conditions, a stretchwoven vest is a winner.

We do wish that the Glacier included a small Napoleon pocket to stash a packet of Gu or two.

Soft Shells
The purpose of this forum is to discuss the design and performance of soft shell clothing, especially as related to the wind resistance, water resistance, and breathability of stretchwoven garments. One debated concept is the efficacy of denier gradient-induced moisture movement, by which a fabric promotes the wicking of moisture from its inner face (which contains large diameter fibers and/or larger interstices between the pores) to its outer face (which contains small diameter fibers and/or smaller interstices between the pores). Examples of denier gradient fabrics, and fabrics / fabric constructions, that are otherwise designed to promote directional wicking, include Powerstretch, Parameta S(Paramo), shelled Driclime, Pertex-and-Pile (or microfibre pile), Dryskin Extreme, Climawool, Pertex Equilibrium, and others. As a basis for this discussion, the reader is referred to the article:

as well as many of our reviews and other articles about soft shell apparel.

The abstract to the Soft Shells article gave me the impression there would be some discussion of the so-called denier gradient fabrics. After reading the article twice I still don't see it, although I am not specially conversant with the technical details important in this area, so I am not sure if I missed it.

I am curious whether anyone has experience with the Paramo shells. They claim their fabrics are not only waterproof and breathable, but capable of (and willing to) move liquid water from the inside of the fabric to the outside. This is a powerful claim, and if true would seem to consign Gore-tex and whatnot to the same scrap heap of obsolesence that the slide-rule enjoys.

Ok, so there's not much interest in this so far. I bought one of their caps; it kept my hair dry in the shower for about 10 minutes. It seems to work well if it's not raining, or for up to 45 minutes if it is raining; don't know if it's breathable yet..

John - hopefully, the new article on Pertex Equilibrium will give you some insight into how a denier gradient fabric works. We'll put Paramo's Parameta S denier gradient fabric on our list of fabrics for creating technology overviews about.

Pertex Equilibrium: Shell, base layer or both? on 01/15/2004 22:48:28 MST Print View

Thank you for the education on Pertex Equilibrium. I am confused, however. Each of the garments discussed and pictured is described as a "shell," yet you opine that they can make for "excellent base layer choices in the fringe . . . and winter seasons."

"Base layer", as in nothing else between the Pertex Equilibrium shell and the skin (yes, I know you state that it is quite comfortable next to skin--particularily the lined ones). If used as a "base layer" then what is the next layer? A mid layer? An outer layer? And if there's a next layer, is the Pertex Equilibrium "base layer" really still a "shell"?

Perhaps I'm misunderstanding how these "shells" are to be used and am assuming too rigidly that they are always used as the final outer layer.

Cheers.

Waterproof/Breathable fabric evaluations? on 01/16/2004 00:04:03 MST Print View

I, like I'm sure many of your readers, would greatly appreciate your evaluation and comparison of the various waterproof/breathable fabrics (e.g. Gore-Tex XCR, Precip Plus, etc.). Which are the best performers? Is an Red Ledge waterproof/breathable hard shell for $100 really comparable to a $180 Marmot Precip Plus or a $350 Gore-Tex XCR hard shell in terms of performance?

I would say that the GoLite Energy is least suited as a base layer. It is made with Pertex Equilibrium that is unlined, so there is no tricot or knit lining that serves to provide both warmth and improved moisture transfer (by absorbing sweat, and distributing it over a larger surface area so it can more efficiently be transported through the Equilibrium). Thus, I think the GoLite Energy would be a fine shell over any knit base layer.

The Rab V-Trail top has a microfibre pile lining - about the weight of a very light tricot - and is a superb next the skin layer. In essence, the lining provides the same function as a conventional base layer (soft feel, wicking, insulation).

The Buffalo Equimax Jacket and the Parrot Concure Pull-On both have Coolmax linings, which are very light, reasonably comfortable next to skin, and provide excellent wicking ability. The Parrot Concure, in particular, it a great design that is ideally suited for a base layer, although it is a little long for my taste (it is long because it's primarily marketed to the bicycling community).

How to integrate a garment like this (i.e., the Rab V-Trail Top) with other layers is more fully discussed in the recent artice on winter clothing:

Both Gore-Tex XCR and eVENT will be featured in upcoming fabric technology articles.

Because of the wide variety of so-called 'proprietary' technologies like Marmot "Precip", Mountain Hardwear "Conduit" and the like, it's impossible to feature each of these technologies in depth. So, they are going to be treated as a family of technologies that will be discussed in the context of PTFE membrane/laminate technologies in a comprehensive technology overview of waterproof breathable fabrics in general, which will be published this month.

laminated fabrics on 01/16/2004 18:56:14 MST Print View

Pertex Equilibrium sounds like a promising new fabric. My question is in reguard to a garment's abilty to evaporate heavy rain.

Will a multiple layer laminated fabric worn as a baselayer be superior at evaportation to a garment with two separate layers or a shell worn over a baselayer? The difference being that body heat is driving vapor through the garment more directly in a laminated product where with multiple sepaqrate layers the air between layers insulates the outer shell surface. Any insights are appreciated.

While descending a hill in a bitter north-easter yesterday, my two-layer, soft shell Mountain Equipment pullover evaporated sweat away uncomfortably quickly. I was very cold for a few minutes. A combination of Parameta shirt under a Berghaus Inferno windshirt has, in the past, given me a similar experience.

On the ascent of the next hill, with my back still to the wind, I found that the two-layer pullover was easier to ventilate than two single layer garments. Nevertheless, I prefer the two garment combo as the older fabrics are nicer to the touch and quieter than the new fabrics used in the ME soft shell.

Evaporating heavy rain away in a cold wind just doesn't bear thinking about. As cold winds can occur at any time of year where I live, it seems to me that a genuinely waterproof coat should always be carried when backpacking in the mountains. They are getting very light so there is no good reason for not carrying one.

Best wishes, John D.

Paramo on 07/14/2004 02:37:25 MDT Print View

I've used the normal range of gortex, triple point etc over 17 years of working and playing in the UK mountias. As a soft shell I have found paramo (I use a lite weight smock) to be by far teh best. Like all soft shells it is slightly to warm for a humid summer day. Thats when I use Pertex over a Merino top.

Not only does the Paramo outperform all other fabrics in terms of breathability and comfort while keeping you dry it is VERY durable. I use mine every day for three years, no "normal" jacket can take that abuse. All I do is stick it in the washing machine and use the waterbased reproofer. Magic!

Enjoy

Epic or other encapsulated fabrics on 07/28/2004 02:27:25 MDT Print View

I've used epic and really like it. I'm finding it harder to find any jackets now and can't find the heavier stretch nylon Epic. Why aren't more companies making garments of this type of material.Does anybody know,Thanks.

Pertex Equilibrium in sleeping bags? on 08/22/2004 18:06:22 MDT Print View

Hello -- your article was very helpful, as always, but I didn't see any mention of Equilibrium used as a sleeping bag outer fabric. Marmot and a couple of other manufacturers are now offering this, and I'm wondering how this fabric would perform (especially in winter conditions) as opposed to Dryloft or Epic?

Many thanks!

Karen-

Are you sure you've seen Equilibrium used in Sleeping Bags? I thought Marmot's "EQ" bags use Pertex Endurance Fabric.

Pertex Stretch Equilibrium on 12/11/2004 10:13:39 MST Print View

I for one am interested in the new stretch version of equilibrium. I think it will have a greater comfort range than all others fabrics and actually be able to used in all 4 seasons. My Arc’teryx power shield lightweight jacket is only good in cold weather so I sold it. The Berghaus jacket out now weighs in an 11oz and the new Montane jacket due out in the spring is an ounce lighter and look to be able to do what most of us want a soft-shell to do.

Those Paramo and Buffalo products look intriguing too though. I wish I had the money to try out all this gear to find out what works best for me.

Cloudveil Inertia == Schoeller Dynamic?!?!? on 01/31/2005 09:19:30 MST Print View

This past weekend I was in the local outfitters in Sylvania, OH (outside Toledo) and noticed they had a pair of Cloudveil Prospector pants on the clearance rack (wrong size!). There was a Schoeller Dynamic hangtag on the pants. This surprised me. I thought Inertia was some sort of proprietary fabric. Maybe the pants were a couple of years old?

Also, assuming the pants truly were Schoeller Dynamic, I was surprised at how thin the fabric is. For some reason I thought Dynamic was a bit thicker. More like Powerstretch.

So, how does Dynamic compare to Inertia?

Unfortunately, no one in my area carries many softshell garments (save for the Windstopper and some Powershield), so I rarely get to touch-n-feel the fabric first hand.

Dynamic compare to Inertia on 01/31/2005 09:52:58 MST Print View

Dynamic and Inertia are very simular. I believe Inertia is a bit lighter / sq yard, and the fibers seems to be smaller which results in a slightly softer and lighter shell. They seem approx the same when it comes to wind and water resistance. I have found Inertia to be more comfortable against the skin, and Inertia seems to more comfortable over a slightly larger temp range. Dynamic is definitely more durable. After a year my Intertia pants where showing wear and the Dynamic pants looked almost new.
