Fellow BC’er here, I have a 20 degree, plenty warm for me I have pushed it just below temp rating (let’s talk Canadian, so roughly minus 7 Celsius) with a merino layer I was still warm. This past season sheep hunting it was way to hot and didn’t have the rain fly on the tent, and I was a long ways a way, a quick 1 hour rain squall came through and soaked the bag, was still wet when headed to bed and dried up nicely through the night. Velcro doesn’t bother me, my only complaint is I wish the zipper went further down the bag. I’m sure it’s a weight savings thing. Not a deal breaker but harder to let a leg out to cool down if I’m too warm. Like stated above it doesn’t compress as nice as a down and is heavier. But I’ve been in enough wet situations that I’d prefer the synthetic.
