It's been a couple of weeks since my Revelation Apex (slim/short 20) arrived and I wonder how I ever did without it. The fit is perfect and it's kept me warm despite foggy 4°C outside the tent. Just know that when they say "for those who tend to sleep colder, we recommend a rating about 10°F lower than the conditions they’ll likely be out in to accommodate that", they mean it. I went for the warmer and slightly heavier quilt and did not regret it. As promised for the APEX, damp conditions did not significantly affect the insulation. But it sure helped that I was able to dry out the quilt during the day. The quality of the zipper, cord locks, snaps and the fabric (I chose 10 Denier plus weather resistand stripes) is fine. Still, as with any lightweight material, they prefer to be handled with a little care. It's a great quilt I'd love to have with me during Spring and Autum. And for the upcoming Summer, I am looking forward to the 40° Revelation that I already ordered.
