3.5 oz with an extra oz for the prefilter is so much lighter. I read you need 1.75 inch dia opening, 1 liter or less volume for Steripen. BB is your Nalgene standard or have they come out with something lighter now? I'm thinking my store bought cheapo but lightweight bottles are shy from the 1.75" dia. opening I'd need.
