LifeStraw Peak Series Straw vs LifeStraw Peak Series Solo Bundle

Both are the same Peak Series hollow-fiber filter, so water protection is identical: bacteria, parasites and microplastics out, no chemicals or viruses. The Solo is the lighter, faster option at 1.7 oz and a 3 L/min flow rate, and it screws straight onto a standard 28 mm bottle. The Straw adds a removable threaded bottom cap for gravity hoses and bottle attachment, but it is bulkier and slower. Buy the Solo for ultralight hiking and everyday bottle use; buy the Straw if you want to drink straight from a lake or rig a gravity setup.

• Choose the LifeStraw Peak Series Straw if you want to drink directly from streams and lakes or attach the filter to a gravity hose or wide-mouth bottle.
• Choose the LifeStraw Peak Series Solo if you want the lightest filter that screws onto a standard water bottle and refills fast on the move.
