I couldn't get that link to work, but I think this one works
Sigg Stainless Steel Flask with Cup From what I understand,
this flask is steel not aluminum. Do you know the total weight of the flask + cup?
There you go, I fixed the url (I had a period at the end of the url). Thanks for the post.
I don't have a scale here at work, nor anything at home that can measure the weight of it, but i'll find one for ya. I'm pretty sure the cup is steel, but I will look into it. Its not a 'heavy' thickness (which is questioning that it is steel), but sturdy for the job.
I'll find out that info for ya... (just sent an email to Sigg, will post back with info regarding cup material)
