Versatile Wings and Water Bottle Holder
The versatile wings of your Heather bag also double as a snug water bottle holder when they’re folded into the bag in Silhouette 1. There’s one on either side of your bag. To use this feature in Silhouette 1, insert your water bottle between the elastic circular loops.
If you choose to convert your bag to Silhouette 2 while using the water bottle holder feature, your water bottle will end up in one of the separated outside wings and be easily accessible.
