TABLE OF CONTENTS

Andrew, the tester:

I am a 46 year old male, 180 cm (5' 11") in height, I weigh 104 kg (229 lbs). I have been bushwalking in Western Australia for approximately five years. For the past four years I have been regularly walking and leading on and off-track pack carries with the Perth Bushwalkers Club. I have also got into geocaching. I consider myself as moving towards being a lightweight tent-carrying bushwalker with my pack base weight in the 8 to 12 kg (18 to 26 lb) range. I have completed my End to End of the Bibbulmun Track (2003), the Cape to Cape Track (Nov 2001), the Coastal Plains Walk Track (numerous times), the Larapinta Trail (July 2005) and Fitzgerald River National Park (April 2006).

I am a regular wearer of thermals on my bushwalks finding that I tend to feel the cold more when I am out in the bush.  The thermals I am familiar with have a different material mix than the Zyflex's being tested, with the thermals I wear being of a polypropylene material.

Andrew's testing playground:

The bushwalking environment of the south-west of Western Australia allows for bushwalks and backpacking from coastal plains to forest. Elevation ranges from 0 to 585 metres (0 to 1,920 feet). Within this region, I walk in varying conditions from forestry roads, to sandy tracks to single-purpose walking trails, to rock hopping, to beach walking to completely off-track walking through open and dense country.

 

 

 

The testing environment:

During the summer period, daytime temperatures average 30° C (86° F), whereas from March through to December the daytime average temperatures range from 15° C to 26° C (59° F to 79° F). During the autumn, winter, and spring periods the normal weather pattern is fairly wet with frequent heavy rainstorms evident. It does not normally snow in Western Australia.

According to The Times Atlas of the World (Concise Edition - Revised 1997) our weather is described as being "Mediterranean - rainy climates with mild winters, coolest month (July) above 0° C (32° F), but below 18° C (64° F); warmest month (February) above 10° C (50° F)." The atlas depicts the coastal area north of Los Angeles as having the same climate.

Item Receipt:

Received both the Thermal Shirt and Pants in good condition and as pretty much as expected given the website description and that they are, after all a pair of thermals (tops and pants). What I was not expecting was the feel of the material. In terms of sizing the pants size is perfect and was as expected given the website details. The shirt is a bit smaller than expected given the information on the website. Had Zyflex offered a larger size, I would probably have taken it, even though XXL in thermals is normally okay for me.

First Impressions:

Interesting material, scary colour for the pants and different to what I expected.  On to the Thermal Shirt first.

Zyflex Thermal Shirt CollarThermal Shirt

The material that the Thermal Shirt is made of is described by Zyflex as "patented, breathable, [and] water-resistant." This material is a mix of polyethylene (59%), nylon (35%) and Lycra (6%). The shirt has more of what I would call a loose-fit hanging t-shirt cut rather than the tight fit that I am used to with my thermals. The cut, means that the shirt has an extended back, and what the Zyflex calls, "raglan" sleeves which have interesting cuffs. The other interesting feature is that tags are on the outside.  One of the other testers has described the feel of the material as being of light canvas. I would agree, it does have a canvas feel to it without evidence of the scratchiness or roughness I would attribute to canvas.  Other than finding the size a touch smaller than I expected. Had Zyflex offered a large size, now that I am in receipt of the Shirt I would have taken a larger size, my first impressions are positive.

Thermal Pants

The pants are made of the same mix of material as the shirt, namely polyethylene (59%), nylon (35%) and Lycra (6%). Interesting they have a stretchy waist band and cuffs at the ankles. The other feature of the Pants is that they have reinforcing at the crotch and a fly (no zip or buttons). I suspect this would be nice addition. While I am still trying to get my head around having white long-johns, I am comfortable with the fit of the pants.Zyflex Thermal Pants

Testing Strategy:

Testing of the Thermal Shirt and Pants will of course focus on wearing them during the forthcoming winter months on bushwalks and camping and also on how  they handle regular washing.  In particular my testing will focus on:

  1. Degree of warmth provided by the Thermal Shirt and Pant when used in combination with my Sierra Deigns Osage sleeping bag and when worn as camp warm gear;
  2. Durability of the Thermal Shirt and Pants during normal wear around camp (often wear my shorts over my thermal pants in the morning for example before heading out of camp) and of course when sleeping;
  3. Impact of regular washing on the Thermal Pants and Shirt. Does it cause the material to soften? Does washing accelerate the wear of the pants and shirt?
  4. Comfort of wearing the Thermal Pants around camp and sleeping;
  5. Comfort of wearing the Thermal Shirt around camp and sleeping;
  6. How does the colour (white) of the pants cope with camp life? Will it quickly stain or dull?
  7. How well does the Thermal Shirt breath whilst worn sleeping?
