Input:
Question: nalgene
Document: Maybe it's only meant to be carried upright, but that defeats my intended purpose of throwing it into my bag. I'll try the Nalgene flask next to see if it is leakproof.
Very dependable and doesn't leak. I tried a few metal flasks on amazon but this is the first I can trust to actually not leak. Fits in pocket nicely (sticks out a ways, but that's to be expected). Cap and bottle are very durable, feels like nalgene quality.
Caveat emptor then good buddy...and happy trails.EDIT: Should also mention that this thing is made of the same material as Nalgene (PET/ Polyethylene Terephthalate) but is actually thicker than what Nalgene uses in the design of their own flask...so It's much stronger. I still use this thing for various occasions and camping over and above the stainless steel flasks I've accumulated over the years because it does resist damage and drops far better.
was looking for a plastic see through flask and found this lil guy. fits perfect in the jeans, easy to clean and light. love it.
Works for just what I need, tough plastic so it will survive and holds a ton. Considering getting a second
Works as expected. Fits into my jacket pocket easily and allows me to ski and not have to stop, take off my skis just to get a drink of water
Why didn't I find these earlier?They are tough, light, and don't taste metally. It holds enough to share.Cheers
What can I say, it held my booze. It was also an ounce lighter than a stainless steel flask, which is important when hiking.
We were looking for a nice flask that was sturdy and lightweight. This fits the bill perfectly. Wish the opening was a little bigger, to make filling it easier, but if you use a funnel, there are no spills.
Used this to hold an adult beverage for a skiing trip. Was able to hold plenty of 80 proof whiskey for 3 people to share on a day of skiing. No plastic smell, the black grippy part makes it easy to hold with gloves on.
Answer: yes
