I have a Nautilus Pro Series Snowsuit cause I swim like a rock. Have no problems with it the suit being stiff. It is a Bulkier suit but that is from the amount of Foam that the Suit has.
Suit is Canadian Coast Guard approved and has Neoprene Cuffs for the arms to keep out the snow and water. It has a built-in Suspender so you can wear it as a half shell for warmer days.
Downfall to this Pro Series line is that they are in the $600.00+ range. Have not tested it out personally in the frigid water though.
Not sure what CT has for sale but check to see if it is CCG approved. When it comes to personal Safety on the Ice, you can't put a value....
Would recommend to purchase a set of Ice Picks also. These are about $10.00 a set. Worthwhile investment should you ever go in and need something to help you out of the water faster and back on to safer Ice.
From Nautilus site:
All CCG Approved Adult PFDs have the same minimum amount of buoyancy, 15-1/2lbs. As a reference, the average adult weighs approximately 8lbs in the water.
Many larger people will ask the question, "How do I know the PFD will float me?". For larger sized people, they can be assured that the device will float them. An approved PFD has a minimum of 15-1/2lbs of buoyancy - larger sizes, incrementally increase in buoyancy simply by the increase in surface area and the resulting increase in the amount of foam required to make that size. The rule is "If it fits you, it will float you".
All PFD's that are DTC (Department of Transport Canada) approved have been submitted for testing by Underwriters Laboratories of Canada (ULC) and approved in accordance with DTC regulations. That means that not only the design passes the approval criteria, but every component used on the device does as well.
The testing that ULC performs on a device evaluates not only its flotation characteristics, but also the strength of its design and construction. If a manufacturer makes even a small change that could impact any of these characteristics that have been tested for, they must resubmit the revised design for evaluation.
Although Lifejackets are approved by the Department of Transport (not Canadian Coast Guard) they still must comply to a very similar approval regiment.
Where a traditional lifejacket had approximately 35lbs of buoyancy, a PFD has a minimum of 15.5lbs of buoyancy. Where lifejackets were designed to self-right people into a face up position in the water, PFDs do not. PFDs do have a marginally higher amount of flotation in the front of the product to achieve a safe flotation angle, but they are designed for comfort as well as safety.
