Product Description

The Gym Sling Bag is a single strap backpack well suited as a gym bag. Open side pocket  and a main compartment with a #10 YKK coil zipper entry.  Large enough for the essentials, but not too cumbersome.  This gym sling bag makes a great team or event bag.  The North Atlantic Gymnastics Academy of Rockport, Maine has outfitted their gym team with this bag and a custom team logo.  If you would like to order a North Atlantic Gymnastics bag, click here.  This gym bag carries a 10 year warranty rather than the 100 year warranty of most other Sailsmith Bags.

 Why buy a Sailsmith bag instead of a “big brand” bag?

A Sailsmith Bag is produced by one person, me.  I fabricate your gym sling bag from start to finish, ensuring the highest quality available.  As I offer a 100 year warranty I am confident in the durability of every Sailsmith Bag that passes out the door into a customers hands.  There are no little “errors” glossed over by trim as may happen at a larger bag making facility with workers who are not as concerned about quality.   Your bag will only cost a little bit more and you will always know who made your Sailsmith Bag, me, A. Christos Contakos.
