Ion8 water bottles are 100% leakproof, with a vented and smooth liquid flow for rapid hydration. They are sealed using removable food-grade flexible silicone seals, which can be replaced in case of loss, damage or degradation over time.
These new style seal sets are Phthalate free, non-toxic and are made from the same material as the original seals from a new bottle. They combine the older style separate air vent seal and drinking spout seal into one big seal, which fits all 2.0 lids.
