I was feeling guilty about all the disposable bottles I took to the gym and finally invested in a Sigg. I'm very happy with it. It's easy to clean (though I only drink water from it, which I'm sure helps) and easy to drink from. Water tastes much better from this bottle than from plastic. It's lightweight enough that I don't mind hauling it to the gym with me. I got the screw top because I don't like those little squirty tops and it is no trouble to drink from. The loop makes the bottle easy to carry and easy to unscrew.My only regret is that I ordered a very plain design. I didn't feel like spending the extra $$ on a more intricate, colorful design when I didn't know if I'd like the bottle, so I picked the cheapest one available (a gunmetal grey). I did recently receive a prettier green bottle as a gift though.A Sigg bottle in a nifty design would make a great gift for any fitness buff. Smaller versions would be good gifts for kids, too.
