Received quicker than expected!

I received this item 2 business days after I ordered it. I was very please with how quickly it got to me. With everything going on in the world right now shipping has been questionable. That being said, I was slightly disappointed when I opened the lid of the bottle and the gasket was shoved under the ribs of the lid seal. I had to use needle nose pliers to get the gasket out in order to clean it before use. I washed it yesterday and filled with water today and it seems to be holding water fine so far.

awesome except cleaning is kind of a pain

I love this bottle. Bought it for travel and to keep in my purse. Use it for my hot coffee and cold drinks. The only drawback is that it’s extremely difficult to get the seal out to clean. Other than works great, keeps things hot/cold for longer than you’d expect

Lightweight and Leakproof

I use mine daily. I selected it because it was lightweight and had a seamless interior. It's traveled many miles with me at work. I use it mainly for water. It's maintained temperatures well. Any leaks were my fault for not securing the lid.

Love the 17oz Microlite

I mostly use for cold drinks. Easily keeps cold all day. It is SUPER lightweight yet works great. Also love that it’s slim and easy to grip and never too large for any cup holders. I really enjoy drinking out of the version with screw top lid. Easy to clean in dishwasher. My favorite drink container ever!

Slim fit, best small/tall bottle on the shelves!

GSI is a Spokane Local brand and they make some great stuff. This bottle comes with a standard cap which is exchangeable with other caps from GSI. I prefer this bottle due to its smaller diameter as it fits more cup holders and pack pockets than the other 16oz bottles. Its double walled just like every other bottle in this category and your not really going to be hard pressed to test them head to head as they all do the same thing. I wish the stock level was more consistent on this and other GSI bottles!

does the job at half the weight!

Works great at insulating hot or cold, used in both hot and cold environments. Took on hikes and really appreciated the lightweight since I had quite a few other items to take with me too.

Slim design

I wanted a sleek water bottle that would stay cool and not take up much space. This one was perfect and the large loop allowed me to attach it to my bag making it accessible.

it’s ok for travelers

I loved how lightweight is on this bottle . I was looking for a thermo and this works perfectly to keep things warm for hours but if you open it several times the heat start to drop down really easily . Another thing is that you need to make sure every time that you close well this bottle or it will leak quite easily , even do I really like it so I think I will keep it

Like the larger size in a streamlined container

Got this for my bike. Fit the holder well and kept my water cool. Only downside was that it disappeared shortly after I used it. I suspect one of my kids also liked it. I will be purchasing another one.

Use it daily

I bought this 6+ months ago and use it daily for my tea. Keeps my tea warm. Lightweight. Easily carted around all day. I didn’t care for the fliptop so replaced that with a screwtop that makes sipping/drinking much easier. I wish they made a 350ml in the same circumference for those times when a smaller container would be more practical.
