Heads up, quicksilver has syncro 543 backzip LFS suits for $145 CDN and GBS for $115 right now.
For a winter suit I recommend the LFS (formally called Pyre) its perfect for local kiting. Coupled with a wind layer and a toque I am good to below zero. Back zip is plenty fine for kiting and goes on and off fast.
They don't last forever, but are great for first couple years. When they stiffen up I cut em into shorties.
