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 have previously tested a Therm-a-Rest ProLite series sleeping mat and own and have used a Therm-a-Rest Classic full length sleeping mat and a Artiach Confort-Mat 3/4 length sleeping mat.

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 above 0° C (32° F), but below 18° C (64° F); warmest month above 10° C (50° F)." The atlas depicts the coastal area north of Los Angeles, California, US as having the same climate.

Product Details:

  • Manufacturer: Therm-a-Rest

The Therm-a-Rest Trail Comfort sleeping mat is part of the Therm-a-Rest Trek and Travel series. Therm-a-Rest describe this series of mats as their "warmest, most comfortable backpacking mattress."  The Trail Comfort is a long mattress (in the regular size, 185 cm (72 in) and is thick at 5 cm (2 in) so this may well be a valid claim.

Specifications for the Regular Size:

  • Manufacturer's specified weight: 1080 g (2lb 6 oz)
  • My weight: 1079 g (2lb 6 oz)
  • Manufacturer's Dimensions: 51 x 183 x 5 cm (20 x 72 x 2 in)
  • My Dimensions: 52 x 185 x NA cm (20 x 72 x NA in)
  • R-Value: 5 as specified by the manufacturer.

Item Receipt:

I received the Therm-a-Rest Trail Comfort in excellent condition; however, was the Trail Comfort as expected given my review of the Therm-a-Rest website?

The short answer is no. In saying no, I am not blaming Therm-a-Rest for my misunderstanding, rather it reflects my experience of sleeping mats being referred to short and long or 3/4 length and full length. On the Therm-a-Rest website, the Trail Comfort lengths are described as long and regular and I took this to mean full length and 3/4 length, which I now understand to be incorrect.  I would suggest that Therm-a-Rest reviews the language used on the website.  The regular Trail Comfort is quoted as having a length of 183 cm (72 in), a measurement I would consider full length. The outcome of all this is that I have longer than expected sleeping mat to test. Hopefully I will have the pleasure of at least four months of enhanced sleeping comfort given I normally use a Therm-a-Rest ProLite 4S 3/4 length!

First Impressions:

Having got over the length confusion what are my first impressions of the Trail Comfort? Well I would describe it as a full length and thick sleeping mat, with a weight which I would consider near or at my weight limit for a sleeping mat. A mat which I think I may have trouble getting into my pack, but a well constructed mat, along the lines I am used to from Therm-a-Rest. Of course these are first impressions and testing will either confirm or dispel them.

Putting the Trail Comfort up against my Therm-a-Rest Classic it appears very similar, making me wonder if this is a re-packaging of the Classic?  The Trail Comfort is a lighter green on top with a black underside. The colouring/thickness of the material makes it difficulty to get an idea of the cut of the internal foam, so can't comment on that aspect.

The Trail Comfort outer layer is made of 100% 150D Ripstop Polyester with a 100% Polyurethane coating. The filling is 100% Urethane Foam.

The mat valve is a screw in/out type with some sort of catch making it difficult to completely remove the cap. Probably a good idea, as I would hate to loose the cap! The mat self-inflated quite well on initial inflation and can easily be hardened by blowing into the valve. Further testing of inflation and deflation will be reported on in the Field and Long-term tests.

This leads to the focus of my testing of the Trail Comfort.

Testing Strategy:

  1. Comfort:  How well does that 5 cm (2 in) of mat handle keeping me comfortable?

  2. Durability:  How well does the 150D ripstop polyester withstand normal usage on backpacking and car-camping trips?

  3. Warmth: How well does that  5 cm (2 in) of 5 R-Value mat contribute to keeping me warm on winter and spring night's sleep?

  4. How slippy is the mat when used on surfaces such as silnylon tent floors, nylon tent floors and hard wooden bases in campsite huts?

  5. How easy is it really to carry? How small does it pack down? Can it be added to my  weekend gear load okay?

  6. How well does it inflate/deflate? Does it hold its inflation overnight with a 104 kg (229 lb) sleeping on it?

At this stage of the test I have a week long geocaching and car-camping trip planned which will see the Trail Comfort used six nights in a four-person tent and three weekend backpacks which will see the Trail Comfort carried as part of a weekend load and used in a silnylon floored tent and possibly at least one night on a hard wooden floor in a campsite hut.
