INTERESTING CORRESPONDENCE
My discussion about people asking questions of manufacturers and retailers is causing some people to actually question them. In this case Stuart went to REI and sent them the e mail letter below. He sent this to me with their response.
Wiggy,
I used to order a lot of items from REI when I was backpacking back in the 60's and 70's.
I decided to look at the REI web site yesterday to see what they have been offering for everyday wear and for hiking.
I looked at their jackets and parkas and noticed there were some with the REI name and noticed many other companies on their site that offer their own brand of clothing.
I looked at the Arc’teryx Fission SV insulated jacket that was said to be waterproof and breathable. I checked out the Mountain Hardware Stretch Down jacket that was listed as water resistant. To preserve warmth.
I looked at the REI Magma 850 Down jacket where the down has been treated with a water repellant (DWR) treatment to help you keep warm and dry. The coat has a stretch knit liner that is more comfortable than a convention ripstop material.
I also looked at the Patagonia Triolet rain jacket and wondered how this product would be able to keep you dry and not clammy in a downpour.
What I noticed with most of the outer wear was that it had tons of sewn through cold spot stitching to keep the insulation in place and to also make it look very cool and fashionable. Some of the jackets remind me of a washboard that was used for washing clothes in the old days.
They give their products all kinds of wonderful names and some sound "space age." They sure do use a lot of hype in the marketing techniques.
I wrote to REI and asked them to explain what this (DWR) treatment of the insulation both in their rain jackets and regular jackets was all about.
Here is the reply the sent me today. Don't know if it makes that much sense or not?
REI - Rainwear |
Hello,
Thank you for contacting REI regarding how rain wear works. Waterproof/breathable jackets are a very scientific part of rainwear. Jackets that are both breathable and waterproof start with a transfer of water vapor from the inside of the jacket to the air outside using either waterproof breathable membrane. This technology will take perspiration created from the body and transfer it through the layers of the jacket to the outside of the jacket where it is released. This transfer happens in part because the warm, moist air inside is attracted to colder, relatively drier air outside. The water is attracted to a layer on the inner membrane of the jacket and slowly moves to the colder outer layer of the jacket. Once on the outside of the jacket the moisture evaporates. The outer layers of the jacket also allow for a water repellency. In addition, each jacket of these jackets will come with a DWR (durable water repellent) finish that effects the exterior of the rain jacket and allows water to bead up and roll off the jacket. This DWR does not inhibit beathability because it bonds to the jacket rather than coating the jacket. This a very scientific process and is very detailed. If you would like more information about the scientific process of waterproof/breathable rainwear, please visit the following link that give a more detailed explanation of how rainwear works: https://www.rei.com/learn/expert-advice/rainwear-how-it-works.html You may have already addressed this (DWR) process before in one of your newsletters. For me I am sticking with your products to keep me warm and dry.., they make more sense. Stuart Flynn |
As you can see their view of waterproof and breathable fabrics is very scientific. I view their response as gibberish.
Below is a testimonial from a fellow in Finland.
Hi
Just wanted to give you some feedback of the Barron Grounds parka
Currently in Finland and the temperatures are moving between -9c to -15c and the parka is sometimes too hot for this :)
With only a T-shirt underneath I feel toasty and sometimes need to open the zipper to cool off.
Fantastic coat!!! Couldn't be happier
1st class gear!!

NEW VIDEO
This week I will be making a new video where I weigh a multitude of garments since I have had numerous requests for the weights. I haven’t bothered to weigh garments because I believe the ability to keep a person warm is more important. In viewing the garments that were shown by various companies at the OR show not a one has a temperature guide but many have weights and as Stuart says they use “space age” names for their garments suggesting that they will keep you warm.
If you go to the web site you will find that I have increased the number of jackets using the DUCKSBACK material. What I haven’t mentioned about the DUCKSBACK material is how soft it is and that it just doesn’t seem to hold wrinkles. Coupled with the Lamilite you WILL think you are wearing a down coat without the water absorbing properties of down, or all of the stitching which is quilting that represents cold spots all over the garment. There will also not be any down migrating through the down proof material either. Then of course the price for a supposed equal temperature rated garment is double the cost of the Lamilite insulated garment that actually does work at the temperature I state about the garment. Last but not least is the feel, which is the same as the finest down if there are no quills in it.
I am also going to make a lighter weight comforter since so many comforter buyers say the current one is sometimes too warm.
As for the video, I am going to try and have it up loaded for the weekend, so those looking for something other than the super bowl there will be me.
