Sigg - Aluminium Bike Water Bottle - Move MyPlanet Alu - Climate Neutral Certified - Lightweight - BPA Free - Alu - 0.75 LClimatePartner certified

I really like it. It's not noticeably heavier than a plastic bottle, it has no plastic taste (obviously), and the spout can be completely disassembled for FULL cleaning, so there are no hidden nooks for mould to grow in. The spout didn't seem particularly secure in the closed position at first glance, but it hasn't leaked at all yet, even when I shook it as vigorously as I possibly could to try to make it fail.It sits very securely in my bottle cages, but it's obviously not going to be perfect for every setup. I use those dirt-cheap metal cages (the ones that are essentially a bent piece of thick gauge wire) because the clamping force can be adjusted just by bending them slightly, and they work perfectly for this bottle. You might have less luck with a cage that can't be adjusted, so buyer beware on that front.

Seems like a good quality bottle. A little small for my bike bottle cage though; putting the bottle in a sock would sort this.A first I didn't think the spout was very good but then realised that in order to get the water out I had to let air in! So in order to get good flow tip the bottle at about 45 degrees and allow the water to flow, rather than covering the spout with your whole mouth.

Looks good but the top leaks constantly. Oddly designed without any means to prevent the bottle losing water even when in the bike.

I bought this as I didn’t want to buy another plastic bottle, the blurb specifically stated it fits existing bottle cages but it’s not true. It’s rattles around so much it would fall out if it was left in. I went to my local bike shop and they said it’s a known problem with Sigg bottles and cages are standard size so it not possible to buy a smaller cage. These bottles aren’t cheap and a company like Sigg shouldn’t be selling them as bike bottles when they clearly don’t do what they say they do.

Really good bottle, well thought out easy to remove and clean parts but it does not fit in a bottle cage! It rattles like nothing on earth and eventually falls out on the smallest bump in the road.

Really good quality as expected from sigg and more comfortable to use with the silicon tip compared to traditional sports bottles. Doesn’t leak either. As others have noted, slimmer than other bottles but most flexible plastic cages fit. Fits perfectly on my carbon c.
