I picked up the Hikesity 'By You' 16oz bottle and had fun choosing from the 576 lid, body and boot combinations. The 316L surgical-grade inner lining really does keep water tasting clean with no metallic aftertaste. The patented lid opens one-handed in about a second and has been fully leak-proof in my bag so far. Vacuum insulation kept my drink cold well past a full day. The silicone boot protects the base and stops that clanking sound on desks. Solid build, and the lifetime warranty is reassuring.
