I can give you insight on them. they replaced the original Lift suit. the floatation material was redesigned as to how it was sewn into the parka and bibs. it is a slightly less bulky float material too. there was a inner liner/fleece jacket added that can be taken out as needed depending on the weather. zippers now have magnetic flap covers instead of Velcro. has under arm vents to release excess body heat when needed. comes in three different color : blue/black/charcoal, orange/black/charcoal, or green/black. I have both the Lift suit and the new Ascent suit and like them both. the added liner/fleece jacket makes the Ascent really warm. you can't go wrong with the Ascent suit. the only thing that needs to be noted thou is that there was a slight mix up at the manufacture this year when they put the sizes on the suits they forgot to account for the added thickness of having the liner in the parka. so with that if you normally wear say a Large you would need a XL. I am normally XL and had to go 2XL with my parka. the bib sizes are spot on thou. this sizing issue will be corrected with next seasons run of the suits.
