Why We Like The Hydro Flask 40oz Wide Mouth Trail LW Flex Cap Water Bottle
The Hydro Flask 40oz Wide Mouth Trail LW Flex Cap Water Bottle sheds 20% of the weight of other bottles in its class yet retains all the benefits of a stainless-steel construction. The double-wall vacuum insulation keeps contents cold for 24 hours or hot for 12 hours, while the pro-grade steel holds up against rugged terrain and doesn't transfer any flavor to our bevvy, giving us perfectly crisp sips of H20 on the go.

Great bottle!
[This review was collected as part of a promotion.] This is a great bottle that keeps my water cold and crisp! It is too large to fit in the cupholder of most vehicles, so keep that in mind if you're planning to use this on the go.

Rusting from the inside
Bought 2 of these for the trail and within a year, one is rusting from the inside. Will not be purchasing Hydroflask ever again.

Great Bottle
Loving this bottle so far. Definitely lighter than previous bottles. Seems very well made and should be durable.

Absolutely Love It!
[This review was collected as part of a promotion.] For a long time I wanted to find a non-insulated stainless steel bottle. Non-insulated because I didn’t want the extra weight of the double wall, and stainless steel to avoid microplastics. Surprisingly, this was hard to find. But then I discovered the trail series from Hydroflask, and it was light enough with the added bonus of being insulated! Really impressed with the bottle. It’s just a such a simple and elegant design. I was initially concerned with not being able to to put it in the dishwasher, but the lack of little ledges and catches really makes that a non issue. It’s easy to clean, has a great form factor, and lightweight. It’s everything I knew I wanted and even some of what I didn’t know I wanted. Absolutely love it!

Favorite One
I love this bottle! I am field sales and spend my day in the car driving long distances. After learning how much water I should be consuming I bought one of these for the volume. It fits one of my cup holders in the car which turns out is pretty important for what I need. I add electrolytes, magnesium and creatine and no issues with interior degradation. Its lightweight for the size so easier to carry to the car and maneuver when driving. I added the twist top (which I also love because it fully disassembles for cleaning) which is important because the water runs fast towards you and I was dousing myself on a regular. I'm seriously considering a second one to replace another Hydroflask that doesn't fit the cup holder and is more of a hassle to manage when driving. There is no boot option but thats ok for me and if you were to stuff it in a sack for hiking you'd regret having a sticky boot.

Won’t buy again.
[This review was collected as part of a promotion.] Never dropped…. Within the first couple months insulation failed. Had to return on my dime which was about a third of the cost.

Trail Series
[This review was collected as part of a promotion.] The "Lightweight" feature is awesome when every oz. counts, on long hikes or backpacking.

Straw is too short
It’s a big fail that Hydroflask couldn’t produce a straw that is suitable for this taller container. They put marketing spin this fail saying that when you can’t get anything more, it’s just a sign to refill. That’s absurd. Make a longer straw. Offer it free to owners of this product.

Is there a boot to fit the 40oz bottle please? I got a wide mouth one which fits 32oz and 40oz but is just a wee bit big for the trail series…
