Hey Fellas,
Patrick and I (and now Joe) have discussed the Slick bags in great length over the last few months. We knew that some people thought the temp rating was accurate and some that thought it was way off.
So we decided to test these (along with others) in multiple situations. What we found was pretty simple; if you're a warm sleeper, the temp rating is pretty close to right on the money, but if you're a cold sleeper like me, then you're getting more of a survival rating. If you brea down the weight of the old bags, a zero degree (for me anyway) is actually a 15-20, but our 0 degree weighs in at just under 3 lbs. That's pretty good for a synthetic 0 degree bag when compared to others on the market.
As most of you know that have talked with me on the phone, I love the Slick bag for its durability, but I generally figure a 0 degree is a 15 and a 20 is a 30-35. Like I said before, I'm a cold sleeper, so Patrick and I are on both ends of the spectrum.
Patrick, Joe and myself (warm, medium and cold sleepers) have been testing the new designs a lot this winter and have come up with a new ratings for the center zip Slick. They are warmer for sure, but here's what I feel you can expect (from a cold sleepers perspective) from the new bags.
A couple weekends ago on our shed hunting trip the temps dropped down to 11 degrees over night. I was in the new center zip bag with wool socks and a merino top. My body did not get cold that night and my feet were fine as well. The second night the temps dropped down into the low teens again, but this time I did not were socks or a merino base layer. My body was plenty warm, but my feet did get cold. I quickly rubbed them inside my down jacket and got some blood flowing. After that, I had no issues throughout the night. Keep in mind that I have REALLY BAD issues with blood flow with my feet and this is not the norm for most people.
That was just one weekend out of many, but a good example of what you could expect.
Since temp ratings are so subjective, the new Slick bags will have a warm and cold sleeper rating. This will help people choose a bag a bit more accurately for their upcoming hunt/adventure.
Feel free to call or email me or Joe with any questions about the new or old model bags.
Thanks
