Hydro Flask 21oz Lightweight Insulated Bottle - Celestine

The Hydro Flask 21oz Lightweight Insulated Bottle in Celestine is engineered for outdoor enthusiasts who value performance without the weight. Part of the Trail Series collection, this bottle is 25% lighter than standard 21oz Hydro Flask bottles while maintaining the same exceptional insulation performance. The standard mouth opening provides ideal flow for quick sips on the trail, and the slim profile fits easily into backpack pockets and cup holders.

Built with 18/8 pro-grade stainless steel, the bottle features walls that are engineered to be thinner to reduce weight while maintaining durability. TempShield double-wall vacuum insulation eliminates condensation and keeps cold beverages cold for up to 24 hours and hot drinks hot for up to 12 hours. The lightweight cap includes a flexible perforated strap and aluminum pivots that further reduce weight without compromising the leakproof design. The bottle is BPA-free and phthalate-free, and fits most backcountry water filters for versatile outdoor use.

This bottle is ideal for hikers, backpackers, trail runners, and anyone who wants reliable hydration without carrying extra weight. Whether you're tackling a day hike, commuting to work, or traveling, the lightweight construction makes it easy to bring along. The Celestine color adds a touch of style while the durable construction stands up to outdoor adventures and everyday use.
