Backpacking Background
I have been hiking and camping for as long as I can remember.  I'm an avid runner and day hiker, ski occasionally, kayak, car camp, and generally like to spend as much time outdoors as possible.  I've spent time hiking and orienteering with scout groups, as well as while doing my military service in Israel.  I travel frequently and try to use every opportunity to explore. I started backpacking a few years ago and my trips have been mostly limited so far to shorter ones, although I’m slowly working my way up to longer trips (including trail maintenance work).  Being small, I tend towards lightweight gear, although I’m not one to hit the digital scales with every item – it’s more of a philosophy than a science for me.  I like to think of my style as light, but not without a couple luxuries.

Product Description

Manufacturer: Danalco, Inc.
Manufacturer website: www.danalco.com
Year of manufacture: 2004
Listed weight: N/A
Measured weight: 3.9 oz (111g) for the pair
Size: Small
Colors: Black
MSRP: $49.95

The SealSkinz® ChillBlocker™ socks are black crew socks which come up to the calf - 10 inches (25.4 cm) from the heel.  On the front of each sock (across the toe area) is written, “SealSkinz®, Small, USA” in red, white, and blue letters.  One of the socks has a small blue triangle near the top of the sock with the SealSkinz® logo on it.  (Note: the socks are not marked for right/left wear)

The SealSkinz® ChillBlocker™ socks are three-fold in thickness, excepting the top 1.75 inches (4.5 cm) which consist of a single-layer elastic cuff.  The inner layer is made of (according to the website) “expedition-weight double velour Polartec® Power Stretch™ fleece (7.3 oz. [207 g] per square yard).”  According to the website, the outside layer is “nylon/lycra® spandex offering a durable, flexible, stretch covering. In between the two fabric layers is our waterproof MVT membrane.”  Together, SealSkinz® touts these three layers as creating “a very soft, comfy, warm, stretch-to-fit sock suitable for a whole host of cold, wet, nasty outdoor conditions.”  From my point of view, what this creates is a thick, definitely substantial-looking sock – much more so than my normal cotton socks.  The outside layer of the sock feels not unlike Neoprene. 

The Socks Arrive

I received the SealSkinz® ChillBlocker™ socks Friday night in a small, unmarked cardboard box.  Before continuing, I feel the need to mention that Danalco sent me an email when the socks were shipped, which included a link allowing me to track its movement across the country via UPS.  I was impressed with the fact that the company alerted me as to when the socks were sent and would be arriving.  Hopefully this is a good indicator of customer service

In the cardboard box was a small plastic box containing the SealSkinz® ChillBlocker™ socks and a leaflet containing information on the Polartec® Power Stretch™ material used as the inner sock liner.  The box also contained a cardboard hang tag describing SealSkinz® ChillBlocker™ products and giving care instructions (hand-wash and drip-dry).

Initial Impressions
I was not quite sure what to expect when I put on the SealSkinz® ChillBlocker™ socks for the first time.  I pulled them on my feet shortly after receiving them and in truth found them fairly uncomfortable: one of the socks has a seam running straight down the middle bottom of the sock, underneath the foot (this despite SealSkinz® being advertised as seamless on the website), and I found walking with this not at all comfortable.  Also, the socks seemed a bit snugger my usual ones.  I wore the socks around the house for about an hour, but found myself sufficiently uncomfortable to remove them after that short period of time.
Saturday morning found me on a day hike of about 10 miles (16 km), with temperatures in the mid-40s Fahrenheit (about 7 Celsius).  I was initially concerned about wearing the SealSkinz® ChillBlocker™ socks: after my discomfort the night before, I was worried that wearing them on a long hike might give me blisters. Despite my skepticism, I put the socks on (with a pair of liner socks underneath).  The SealSkinz® ChillBlocker™ socks felt much more comfortable this way, and I found that within about half an hour of the start of my hike I forgot to think about my socks altogether.  Although it was a relatively warm day (and although I was wearing another pair of socks under the SealSkinz® ChillBlocker™ socks), my feet were not too warm by any means.  

Based on this initial test, I’m much more pleased with the SealSkinz® ChillBlocker™ socks than I thought I would be Friday night when I first put them on.  With a pair of liner socks underneath, they are extremely comfortable (though still a bit snugger than I would like).  My only concern at the moment has to do with durability.  I noticed that the inner fabric of the sock seems to be glued to the other layers.  On one of the socks, the ‘seam’ created by this already seems to be coming apart – there are about 3-inches (7.6 cm) along the back of the sock (along the calf) there is about a half-inch (1.3 cm) separation between the two sides of the inner fabric and where the MVT membrane is visible.  The fabric can be further separated without any difficulty at all; although I have no intention of trying to rip the socks apart, I’m a bit concerned that with repeated washing and even normal use the liner might separate from the rest of the sock entirely.  

Testing Plan
I will be using the SealSkinz® ChillBlocker™ socks on all hikes and for daily warmth as long as cold weather persists.  I also plan on using these as sleep socks.  I am anticipating a wide variety of temperatures over the testing period as well as terrain.  The SealSkinz® ChillBlocker™ socks will also be worn during any kayaking trips I will take this spring and other water activities.
I will be testing the SealSkinz® ChillBlocker™ socks for warmth, comfort, and durability over the course of the next six months.  In particular, I am interested to see what the usable temperature range for these socks is.  I will also be testing how waterproof these socks are, and how (if at all) getting the socks wet affects their comfort level.  Finally, I am curious to see how well the SealSkinz® ChillBlocker™ socks hold up, especially considering that one of the seams is already coming apart.  Will repeated washings detrimentally affect these socks, even when following SealSkinz’® explicit washing instructions?
The next two months should see a lot of use for the SealSkinz® ChillBlocker™ socks and I hope to have answers to some of these questions in my field report.
