collapsible liter water bottles?

“Anyone have any experience with these? Do they last? I got an offer in my email for these (same price except shipping included):

“not me”

“No, but I had a Plat that collapsed like that. Worked well but after a year or so, it started getting soft in the outside seams where it folded all the time. It never separated and I still have it, but I only use it to filter water while in camp. I don't trust the seam to hold out much longer and I don't want a liter of water trickling through my pack. I should move it over to the kayak equipment, I could always pump out the water from the kayak if it separates.”

“I've carried a plat, but never felt comfortable with all my water in one container. With the plat in my pack, I'd usually have to take it out and squeeze it to get the last couple of drinks of water. Collapsible liter bottles seem like a good compromise. Also, I have lost empty regular bottles from side pockets when falling or bushwhacking.”

“My first trip with a Cantene stopped me. First time I dropped it it fell down about 20 of sandstone and had a leak.
I have just bought the Sawyer with the liter squeeze bottle but I will designate it for water filtering.”

“I've been a long-time Platy user, too. I keep the opening facing down and don't have a problem getting the last drops out. I agree that having a few smaller containers is a good idea. Haven't tried the brand mentioned in the OP.”
