I ordered the standard style off of guyot's website and they got here today. Unfortunately, my spacesaver cup is 20 miles away at the moment. However, I can say that the standard style bottle will fit in my OR (Outdoor Research) insulated bottle jackets (which are made for the 1 liter nalgenes). Already a plus.

A word of warning to the ultralight crowd...as you may well expect, these SS bottles are NOT light. In fact, I was pleasantly surprised at the heft and sturdiness of the bottles.

The standard bottles will fit standard nalgene caps as well.

I'll report back on the spacvesaver cup fit later.

I'm already a fan of these bottles.
