I just received my Hyalite CC foam pad from backcountryedge.com today. I haven't seen much talk about this pad yet so I thought I'd post my initial thoughts on it.
According to Hyalite's website (http://hyaliteequipment.com/sleeping-pads/view/classic-cc-cc) it's supposed to weigh 14 oz and have an R-value of 4. Mine comes in at 16.7 oz and is actually black, not gray as shown. If the R-value is true, then it'll provide a lot of warmth for its weight. Not as great as advertised, but still not bad. The weight listed on backcountryedge.com's website (10 oz) is clearly wrong and I need to contact them about it.
My plan is to use this pad in the winter time to supplement my normal 3-season sleeping pad setup. The foam itself is fairly stiff and much less "squishy" than a RidgeRest. I certainly wouldn't want to use it without some sort of extra cushioning. That said, I think it would act great as a virtual pack frame.
Not much else to say, really. I mainly bought it because it was only $25, had a higher advertised R-value than the RidgeRest Solar, and is lighter than the RidgeRest Solar. Lawson's 1/2'' EvaRest pads, although they only have an R-value of 3, are so light that they might be another option to look at as well.
edit: I looked at the packaging that the pad came in – it advertises a weight of 10 oz too. I e-mailed backcountryedge.com to figure out what's going on…
