IRON °FLASK Silicone Boot for 32-40 oz Water Bottles | Protective Silicone Boot for 32-40 oz Wide & Narrow Mouth Water Bottles - Shields Against Dents & Scratches (Midnight Black)

Good complement to the Iron Flask bottle in my case of 40oz. It fits perfectly protecting the base from falls, also from scratches due to use, helps to avoid unintentional slipping and makes it quieter to place the bottle on surfaces. The quality is very good, easy to install and well packaged. I highly recommend this boot.

The IRON °FLASK Protective Silicone Boot is a great accessory for sports water bottles. It fits perfectly and provides excellent protection against dents and scratches. The material is durable and adds a nice grip to the bottle. Highly recommend for keeping bottles in top shape.

Fantastic! This is great for a big water bottle! Keeps it quiet when moving it or sitting it down in a quiet room. Prevents scratches and dings all around the bottom and some protection on the side if it gets knocked over. Easily cleaned with hot water and soap. Would definitely purchase again 10/10!

It fits nice but I think they should tack on a couple bucks when you buy the flask and include it, but both this and the flask work well.

This is the best silicone boot I bought for my water bottle, it’s durable and great quality. I would definitely recommend it.

Probably the best looking 40 ounce water bottle boot. I wish it was alittle tighter. The material is not as thick as I was expecting. A bit pricey in my opinion. I would recommend it.

It does protect the bottom from dings, scuffs, etc. It does make the bottle non slip/slide on slippery surfaces as it has a tacky grip. The negative is that it can’t be carried in the side mount of any of the kids back packs. It’s too grippy to shove into the net or pouch style slots and once/if you do get it in, it grips and pulls like it’s going to rip it off/tear it up if you pull it out. It’s just a no go in that regard. 40oz slides easily into the pouches without this device. But then it slides/falls out easily also, which… 🤷‍♂️. For us, one kid now simply carries the bottle everywhere, the other puts it inside the backpack. Neither of them use it in the side mount backpack holders. Thought you should know.

A MUST BUY If you don't want the bottom of your bottle all dinged up this will protect it ! I purchased a few for all of bottles and we love it ! Also you can put in the dishwasher on the top rack 😁
