UltrAspire 1L SoftFlask

This collapsible SoftFlask, developed by UltrAspire in collaboration with HydraPak, introduces a unique shape and carries 1 liter of fluid that is engineered for long-distance performance. The 42mm locking cap prevents leaks while maintaining a low-profile silhouette that reduces body contact when used. Its flexible shape allows the SoftFlask to slide easily in and out of the side pockets of the Traverse and Purist. This 1-liter SoftFlask is also compatible with the bloddle hose attachment, offering added versatility for different hydration setups. PVC & BPA free.
