Chazz Layne wrote a review of GSI Outdoors Glacier Stainless Leather Wrapped Flask on December 7, 2010
Looks, dimensions, capacity, and the ability to share are excellent, but the cut and weight of the leather leaves a little to be desired. One strap on my cap is a little too long - not long enough to cause a problem - but enough to let the cups rattle around a lot and look a little odd sitting on a table. Other than that, I dig it.Mine has not leaked yet, though if it does start leaking it would be a pretty simple task to pop out the plastic seal and put in a silicone one. If GSI is watching, this would be a good thing for them to implement on future models.
