Thank very much for the thoughtful reply.
I guess I should have stated what I use the jackets for. Mountaineering/14ers. 4 season, and ice climbing. The Volant is one of my favorite pieces of gear, but there are a few things that bug me about it. 1- it is a little too short in the torso-I frequently have to pull it down, and 2- I wish there was a pocket or 2 for me to stick water bottles in. If you stick a nalgene in a Volant and start moving it will fall out the bottom since it has no drawcord hem. Also my XL Volant was a bit on the snug side with multiple layers underneath.
I called and talked to Feathered Freinds and they told me that though the sizing chart makes the size dimensions look the same for the Volant and Frontpoint, that the Frontpoint was cut roomier in reality. He also told me to size up one on the Helios.
I ended up ordering the Frontpoint in XL and the Hooded Helios in XXL, and I say a bittersweet goodbye to my XL Volant-it is on eBay.
