SmarTube

I actually really like this product. It does fit multiple bottles and container types. To see a better description/video go over to youtube. Look for Trekker outdoors or smartube. This works well with my goto nalgene bottle. I like the bite cover to keep the dirt out and the mouth piece is round unlike some others. I did cut a small v-notch in the bottom of the tube to keep it from suctioning to the bottom of my nalgene bottle but you could pull it back out a little. Just my preference. Thank you trekker for the awesome product and fast service. I'll be back soon for more.

I hate it that these manufacturers can't say which bottles these things fit. I have no idea what size cap is on a United States one-use Coke, Pepsi, Mountain Dew, 7-Up or USA popular one-use water bottles and it doesn't say on the top of the cap. I recycle all my soda bottles into water bottles and would buy this if it worked. But for ease and confidence, it's better to purchase some .40" od aquarium tube and a bite valve and drill a coke cap to fit with a second hole for a vent. Instant hydration tube under $5, fits everything.This is America, speak SAE.
