UltrAspire Soft Flasks and Bottles


We use a BPA -free LDPE for our running bottles, which is preferred over PP for most sport applications because of its hand feel and squeeze-ability. (We know what it’s like to be a fatigued runner in the later stages of a long race trying to squeeze an impossible bottle!) We also use Tritan, when squeeze-ability is not an issue and stability is preferred, and Silicone, both of which, have great taste quality.
