Here’s Zip geared up for a hot summer commute into work.  We walk in from the South End, so it’s about 30 minutes at pug pace to get to the store on Newbury Street.  That’s too long without packing water, at a minimum.  Today we’re trying out the summer gear:  Ruffwear‘s Swamp Cooler Jacket, and the Kool Collar with frozen gel pack.  We’ve got them both in the store (the Kool Collars are in the freezer for immediate use) but we want to know first hand how well they work. We’ll report back with a review later.
