Hydro Flask

Tactical Line 21oz Flask

Hydro Flask works hard to provide technical, durable, and convenient water bottles for outdoor adventures, and the Tactical Line 21oz Flask is the result of all that hard work. While the color choices keep this flask low-key, the double-wall, vacuum-insulated construction keeps your coffee piping hot from the campsite to the trailhead, from the trailhead to the end of the hike, and from the end of the hike back to the campsite (up to 12 hours). Alternatively, this flask can keep cold drinks cold for up to a full 24 hours. The stainless steel used to make this bottle is BPA-free and resistant to odors and bacteria so your coffee doesn't taste like the sport drink you guzzled down yesterday.
