Standard Adventuring Gear:
Here are some standard items a traveler or adventurer type might carry around with them in a medieval-ish setting. I am borrowing some of the D&D Player's Handbook items, but in my own words to avoid copyright issues.
Backpack: Self-explanatory. A bag or pack made out of leather used to store various items that has leather straps attached to it for easy handling and carrying.
Bedroll: The medieval equivalent to a sleeping bag, complete with bedding and a thin blanket.
Winter Blanket: A thick blanket usually made out of wool.
Candle: A small light source that burns for 1 hour before extinguishing, depending upon the size of it.
Case/Map/Scroll: A tube used to contain rolled parchment, paper, maps or spell scrolls. The tube itself is normally made of tin or capped leather. Useful for anyone who needs to store any kind of written or pictorial information.
Flask: A small thin glass container fitted with a cork or stopper used to hold water or other liquid. It can also be constructed from ceramic or metal.
Waterskin: Medieval equivalent to a thermos/canteen/water bottle. Used to hold drinking water usually scrounged from rivers or lakes with fresh drinkable water.
Flint & Steel: Used to make fires by striking the two together to create sparks.
Ink: Black ink used for writing. Other colors may or may not be more expensive depending on where you go.
Inkpen: A writing utensil made out of a wooden stick with a special tip.
Clay Jug: A basic ceramic container.
Lantern: Operates on using pints of oil to make it burn in an enclosed space. Each pint lasts for six hours. Different than a lamp which burns openly and therefore is more dangerous as it can spill easily. Lanterns are the safer alternative.
Oil Lamp: Burns using oil inside it but can spill the contents easily making it more dangerous to use efficiently. Burning time is the same as above.
Small Steel Mirror: Want to check your appearance? Signal a friend with reflected sunlight? Turn a medusa to stone of its own gaze? Have one of these handy pocket mirrors readily available.
Oil: Used in lamps and lanterns and burns for six hours per pint.
Paper: Made of cloth fibers.
Parchment: Made of goat hide or sheepskin.
Trail Rations: Portable non-perishable food supply consisting of things like nuts, jerky, dried fruit, and hardtack. Highly suitable for traveling.
Hemp Rope: Self-explanatory. Used for climbing into and out of hard-to-reach places or other uses you can think of.
Tent: A simple setup that can comfortably hold no more than two people depending on its size.
Torch: Great illumination for dungeons and other creepy places. A wooden rod with the top part of it soaked in tallow or something similar to it. Can light up an area of a 20 foot radius and lasts for no more than one hour.
Whetstone: A rock used to sharpen weapons by scraping the blade against it.
Belt Pouch: Can store small items on it for easy reach such as potions, flasks, tools and the like. Goes around the waist.
Sack: A small bag or pouch for carrying items such as trail rations. Drawstrings allow for easy opening and closing.
Grappling Hook: Used to secure a rope for climbing.
Various Tools & Kits:
Alchemist's Lab: Contains beakers, bottles, mixing and measuring equipment for alchemy purposes. Variety of chemicals and substances are also common with this lab kit.
Artisan's Tools: Useful for a bunch of crafts and handiwork.
Climber's Kit: Includes items used for climbing such as special pitons, boot tips, gloves and a harness.
Healer's Kit: A typical first-aid kit for wounds of varying degrees. Contains herbs, salves, bandages, etc.
Thieves' Tools: Any thief-type or lock picker should benefit from having one of these in their possession.
Magnifying Glass: Useful as a substitute for flint and steel, plus can aid in getting a closer look at something.
Attire:
Traveler's Outfit: Consisting of boots, breeches or skirt made out of wool, durable belt, shirt with vest or jacket over top with a hooded cloak.
Explorer's Outfit: Much the same as a traveler's outfit, but made of leather instead. Contains many pockets in its ensemble. A scarf or wide-brimmed hat may also be included.
Scholar's Outfit: Usually a robe and soft shoes with maybe a cloak to fasten over top.
Mounts & Related Gear:
Cart: Two-wheeled vehicle that comes with a harness. Usually a single horse or ox pulls it.
Horse & Saddle: Horses are one of the most common and reliable traveling mounts and beasts of burden. Depending on where a character comes from or is going, a horse would be a useful companion for both riding and carrying gear. Saddles can come in many types, such as exotic, military, riding or pack saddle.
Taverns & Inns:
Meals: Depending on how much coin a traveler has on them would determine the quality of the food they get. Poor meals can consist of baked turnips, bread, onion and water. Common meals can make up bread, chicken stew, carrots or watered-down ale or wine. Good meals are usually comprised of pastries and bread, beef and peas with alcohol such as ale or wine.
Accommodations: Poor accommodations can consist of sleeping on the floor sometimes by the fireplace, common ones have a raised, heated floor with blanket and pillow, good accommodations are a small room with one bed, chamber pot and perhaps a nightstand or other amenity.
