I was able to get out last night in my new HRTQ. My old down bag is a bit of a monster i made 20 yrs ago. It weighs five pounds so when the HRQ came my first thought was ,"did they send me the Shanendoah??? LOL. On further inspection i saw that it indeed was the HRQ, i just wasn't use to the light weight and high quality down. So i had my WBBB , my Yeti3, and the HRTQ , and a bit of foam in the FB. I was wearing a touque, cotton tee shirt, cotton boxers and smartwool sox. I went to bed around 10:30. I didn't look at the temp but i suspect it was around 40. I was pleasantly surprised when i got in and immediately felt very warm with the HRQ. I was so warm in fact i had to vent several times over the next 1 1/2 hrs. I was very toasty warm. Temps got down to about 33 degrees and i was still warm. I felt the odd cool spot once and a while as my leg might lean into an uninsulated part of the WBBB but no big deal. All in all i'm very happy with the HRQ. The Jacks make great stuff with high quality materials and their shipping time was fast. The only real problem i have with the HRQ is that now i want to buy more of their stuff.
I wore the bare essentials in the way of clothes so adding some merino wool and fleece to the equation should get me into the twenties. Thanks Jack and Jack
