"Good-quality water bottles that don't taste like plastic, which is a plus. They slip very easily into the vest. The only minor drawback is that the bottom is a little stiff and can press against your ribs when the bottle is empty."

"Good-quality water bottles that don't taste like plastic, which is a plus. They slip very easily into the vest. The only minor drawback is that the bottom is a little stiff and can press against your ribs when the bottle is empty."
"The wide opening and rigid back are super convenient. My new flasks fit perfectly in my Kinetik vest."
" Kinetik water bottles Kinetik high-quality, and I've been using them for 6 years. I just replaced my 3-liter pack this year and reordered some akuaflask with protective shells, along with the drinking straws. This winter, with all the layers of clothing, I had no problems. But now, wearing just a T-shirt, the bottoms of the bottles are hurting my ribs, especially as they empty. I have to blow air into them to keep their shape and make the contact less painful. Too bad! I’m going to have to reorder the flat-bottomed bottles, which never gave me that sensation."
"Practical No 'new plastic' smell"
"Fits very well in the vest"
"A very practical, easy-to-handle flask that doesn't slip at all in the brand's 3-liter hydration pack pocket."
"I've unpacked the product but haven't tested it yet; it looks like a high-quality item to go with my RK15 vest."
"Art"
"Excellent product—I highly recommend it."
"It's much easier to slide the flasks in during refueling stops. The wide opening makes it easy to insert isotonic drink pouches."
