FC/Aeria HSF - Bottle Cap Silicone Inner

Awfully constructed lids. Make you purchase two separately to make the lid all to just fall out while you're riding. I've purchased a new lid on two occasions and had them fall out both times. $5 per half of the lid alongside the shipping. Inherently floored bit of equipment.

The profile design team were absolutely awesome. I lost mine recently and the team searched high and low to find my replacements. Thanks Again
