With regards to undersuits, what is a good weight? Is a 400 gram suit neccesary, or am I going to freeze to death in a 200.
Depends entirely on you unfortunately. One of my buddies is fine down to chilly temps in a 100g Robin Hood job whereas I really feel the cold so I've just got a 400g.
If you can try some out then you can work out what's best for you. Otherwise I guess starting with a 200g would at least allow you to add a base layer if it's not quite enough.
