Pack (got already)
Dry Bags (got already)
Get a separate one for your sleeping bag, wrap spare socks etc.. in freezer bags, this way its easier to grab specific bits of kit and even if something falls on the ground when the main drybag is open its still kept dry.
Stove, Cooking pot, Spork (ordered, on the way)
Forget it if its one of those plastic sporks, take a proper kfs from the kitchen if your cooking proper meals.
Water purifier, e.g. SteriPen
You'll also need a filter bag of some sorts, such as the milbank or equivalent, i've always just used puri-tabs or boiling never bothered with a UV light, remember to take spare batteries if you do.
Hiking poles
Good idea, can be used as tarp poles too
Weatherproof Coat
Make sure this is a good quality one, that comes below the waist slightly, with a good hood. It WILL rain, be ready. If its sunny for all of your trip put a lottery ticket on.
Walking Boots
Best to get mid to high length, low cut boots will let water in too easy when going through the tall grass that will be everywhere. If possible don't bother with Goretex, in heavy rain you socks will seep water into your boots anyway.
Neck Warmer
Good Idea
Harvey's Map of A/K Way
Good choice, very durable, i'd still invest in a decent map case
Tent
Sleeping Bag (I found an 0.8lb one, but it's pushing £250! Cheaper ones, around £40, weigh almost 6lbs! Do I go for weight or cost?)
Go for a mid-range synthetic. Down is great but must be kept dry.
Camel Bag 2-3L
Issue thermobacks are available cheaply from surplus stores and are cracking bits of kit.
Leakproof water bottle 1L
Sleeping Mat
I'd recommend a full length one
Socks
Wool, plenty of. Dry them by wringing them out then having them in you sleeping bag (Only if synthetic) or in your pockets during the day
Waterproof trousers
Again, don't skimp on quality, make sure your jacket covers the waistline
Generic walking trousers
Gaiters
Good idea, these will help keep water + bits of grass out of your boots and socks. A cheap pair would be fine
Crampons (It can be icy or snowy in Scotland in March... maybe MicroSpikes will work better... maybe I don't need anything?)
In march think more Cold and Wet rather than Snowy & Icy, if you need crampons up there you'll need an ice axe too, personally i would avoid this type of weather unless you have some prior experience. It can snow in march of course and the nights can be below freezing, but it shouldn't be a daily occurrence.
Head lamp
Check out the petzl e-light
Multi tool/knife
Firestarter/lighter
I'd recommend a couple of cheap Bic's
Compass
Anything Silva, Suunto, or Recta,,,,with a decent sized baseplate.
Thank you, would be VERY much appreciated! I'm so bad at this kind of thing D:
