To determine the sizing of the equipment, does it depend on the brand or whoever makes it?

There can be variations in sizing - what may be XL in one is a L in another. Best thing to do is to get yourself measured so you know what your sizes are and then you can see how that translates to the equipment you are looking at.

Thanks for all the help and advice. I'm going tomorrow to purchase the equipment.

Fangers,

Those sites are really good. I printed out the one that you said was the best.

I found a camp at my local ice hockey rink - it's about 5 hours a day for a week in the summer.

It seems like flexibility is huge when goaltending. There wouldn't happen to be a website or anything on good stretching techniques to improve flexibility and special areas to concentrate on? I'm pretty sure one of the most common injuries with goaltenders is in the groin area.

There are a lot resources on the web to research - however - try this as a starting point

By the way the camp I am going to attend is Popa's Goaltending camp. I heard he was great with younger players who are just starting. Is there anyone else that has heard of him?

I've also been doing very well playing goalie with dek hockey. The ages range from 16-60 so I'm playing with players who are more then twice as old as me.

I just can't untill this summer to start these camps and the local fall league. I'm also looking forward to joining the school team because I heard that our goaltender isn't very good, doesn't pay attention, doesn't listen to the coach, and is involved in "bad" things.

Check out http://www.gdihockey.com/ (Goaltender Development Institute) for more information. It's probably one of the best camps for goalies and its site has lots of good information about goaltending.
