@molgrips - trailshot is good. Very popular with the bikepackers. If it's just one night then boiling it should be enough
Boiling and letting it cool would be a PITA and require planning (and plenty of gas), so I reckon at that price the Trailshot is worth a.. erm.. shot.
Trailshot is good but the instructions for cleaning it aren't the best. The following comment came from a review on bikepacking.com
MSR Rep In The Rockies here...It's unfortunate that whoever sent you this filter failed to make it very clear that every time you use this filter it should be shaken, very vigorously, for a minimum of 30 seconds. If you do this, you will not see much diminishing of flow rate. All filters will slow down over time. If not I'd be worried. Their job is to take out stuff from water including microbes so small as to require a 0.2 micron absolute filter size (this is extremely and mind-boggingly small). Cleaning these filters by shaking is extremely effective, again, especially if you do it every time you filter. To do so, simply remove the hose (it pops off easily), cover both the outlet and inlet holes with your finger and thumb, and then VIGOROUSLY shake (put your back into it!). Once you're done shaking, simply give the TrailShot a squeeze which will squirt out the bad water (it's surprising how dirty this water is, even when filtering seemingly clean water). I'd also recommend draining the rest of the water out of the hose by turning it upside down (the prefilter has a one-way valve that doesn't allow the water to exit). Finally replace the hose, fold it up against the body of the filter, replace the rubber band, and store.
@montgomery - that looks like Rylstone to me?
My bikepacking tip is that bivvying is nice, but it's hard to get you, your sleeping bag and mat inside the bivvy bag. So, don't put the mat inside the bag.
Also - a good beanie hat helps for many things, including sleeping.
Last - you'll take too much food and water. Just buy food on the way (but plan it out!) and water is everywhere.
You can go very basic and cheap which could be fun for your first bike packing trip (plastic survival bags, whatever sleeping bags you have and a meal of pepperami, cheese, crackers and some booze).
All the decent lightweight kit ain't cheap so I wouldn't invest in anything untill you have tried it.
Or you could maybe borrow some from a friend?

That's Barry Godin. Surely the cheeriest man in British bikepacking.
Although he has competition...
