I'm leaving March 16 for my thru and I was hoping to get the new CleanStream filter, so I emailed Platypus to find out when it will be available. Here's what I received from them this morning:
Thank you for contacting Cascade Designs Inc.Too bad. I'm set on using a gravity filter, so it looks like I'll probably go with a Sawyer filter now.
The CleanStream is due out in spring. Unfortunately it will most likely be sometime in April at this point.
