Love it. For Christmas, I bought this for my college basketball playing son as he has a tendancy to not drink enough water during practice. I had his name engraved on it and ordered his favorite color - green. He loved it and carried it around the house with him until he went back to college (early because of basketball). It was so nice to see there is still some of the "kid" in him that enjoys a favorite Christmas present. It is a quality water bottle and I recommend it to anyone.
I purchased the smaller version of this wide-mouth canteen and while it is just the right size for the cup holder in my car, I find it too small to keep me hydrated through a whole tennis match. This 40 oz. size is much better for longer duration activities. I like the wide-mouth for ease of cleaning. The screw on-off top removes easily for drinking without touching the rim of the canteen, keeping germs at bay. I was a little hesitant about putting the full canteen in my gym bag, but it doesn't leak a drop. I am very happy with this purchase.
I ordered this in the 40 oz. size for my daughter to keep with her during her school day. It certainly holds enough to last until she gets home. The opening is generous so it's easy to clean with a bottle brush. The dark pink color is attractive not too harsh.
