I have the valley & peak quilt with the 167 weight apex. If you're a warm sleeper and have a decent mat it should take you comfortably below zero. I was a little cold just before dawn on an uninsulated mat at -3. Pack size isn't bad but its never going to match down in that department. I have the wide + extra long version so pack size probably suffers a bit due to this. Weight is 800-something grams. I've heard, but have no direct experience, that the 200/233 weights pack down pretty huge and likely impractical for bikepacking.

All in all I really like it.
