The very expensive Garmins have their inReach functionality integrated into them like the Garmin Montana 700i. Not a very user friendly GPS in my opinion, but for boonies riding you get an SOS button for when you need rescue. I've carried SPOT and inReach devices a lot backpacking, they hold up well and are a "peace of mind" that I'm happy to pay for.
I used two Sawyer squeezes for the water I drank during most of 2017 which I spent traveling. Two because I carelessly let one freeze (which ruins the filtration) during a May snow in the Smokies. Pro-tip: put the filter in a zip-lock bag and sleep with it in your sleeping bag or quilt to prevent that from happening. Rigging up two bottles or a bottle and a bag for a gravity feed system worked out great for me even though it was slow. The Sawyer filters are tough to drink through directly like a straw unless you regularly flush/backwash them. For filtering as I drink I've been happier with the Katadyn BeFree. Have never tried a LifeStraw as they never came up as a serious contender for regular use vs emergency use at the time I was comparing products, but I think they've added some products like the LifeStraw Flex since then to change that. You can also YOLO it and just drink water you find straight up, but I'm personally not a fan of giardia.
