Here's what other sites are saying:
Steer clear of harmful BPAs with the Innate Fresco V2 Water Bottle. No inner coatings to contaminate your water, a V2 Collar that is designed for cold conditions, and an easy-to-carry or clip lid design sweeten the pot. To avoid frozen lips on winter days, the V2 Collar is made from food grade polypropylene which gives you a healthy barrier from direct contact with cold stainless steel. Innate also designed the Fresco V2 to fit with bottle adaptors on most backcountry water filters.
