The Zak Designs Park is an insulated stainless steel water bottle with a push-button lid, a fold-down carry handle and a covered silicone spout with a flip-up lock. It keeps drinks cold for up to 18 hours and is BPA free. It suits campers, commuters and kids ages 3 and up who want a leak-resistant bottle that travels in a bag. Against plastic bottles it trades light weight for cold retention and durability; against premium insulated rivals it gives up one-hand operation and a wider lid range, and it must be hand washed.
