Windrose: How to Increase Inventory & Backpack Size Fast

Inventory and Backpack Size in Windrose: How It Actually Works

Windrose ties your progression very closely to how efficiently you can carry resources. The base inventory is deliberately restrictive: you start with 8 quick slots (the hotbar) and 16 regular backpack slots. With ore, hides, food, tools, and quest items all competing for space, expanding that capacity is one of the first practical bottlenecks.

The core systems to understand are:

• Backpacks = more slots: You gain backpack space by crafting and equipping better bags.
• Workbench level gates recipes: Higher-tier backpacks require higher workbench levels.
• World storage complements your backpack: Chests and later your ship reduce how much you must carry at once.

This guide focuses on how to increase inventory and backpack size as quickly and cleanly as possible, then covers efficient material routes and storage setups that keep clutter under control.

Step 1 – Establish a Base and Build Your First Workbench

All backpack upgrades are crafted at a workbench, so the first objective is a small, functional base with a bonfire and workbench placed within its radius.

Early on, do the following:

• Place a Bonfire at a convenient, central location (ideally near starting resource clusters).
• Open the build menu (B on keyboard, or the equivalent on controller) and construct a Workbench (Level 1).
• Make sure the workbench is inside the bonfire’s build radius so it counts as part of that base and can detect future upgrades like the Sawhorse.

Level 1 Workbench is all that is needed for the first backpack upgrade. At this stage, the main constraint is raw gathering speed of basic materials, not complexity of recipes.

Step 2 – Craft the Torn Sailcloth Bag (+4 Backpack Slots)

The first upgrade is the Torn Sailcloth Bag. It is cheap, available from Workbench Level 1, and increases your backpack capacity by +4 slots over the base capacity.

From a functional perspective it should be treated as mandatory: it is inexpensive and dramatically smooths out early gathering and questing.

Materials Required

• 2 × Coarse Fabric
• 1 × Rope

Those break down further into very simple components:

• Coarse Fabric = crafted from 3 × Plant Fiber.
• Rope = crafted from 3 × Plant Fiber.

Total Plant Fiber required:

• 2 Coarse Fabric → 2 × 3 = 6 Plant Fiber
• 1 Rope → 3 Plant Fiber
• Total: 9 Plant Fiber

Efficient Fiber Gathering

Plant Fiber is obtained by harvesting small shrubs and low vegetation around the starting island. It is abundant, but the key for efficiency is to run a tight loop rather than wandering randomly.

• Identify a cluster of shrubs near your base.
• Run a short circular route that hits 8-12 shrubs, then returns to the bonfire.
• By the time you complete one loop and craft, the first shrubs usually respawn.

Once you have at least 9 Plant Fiber, do the following at the workbench:

• Open the Workbench crafting menu (E while facing the bench on keyboard).
• Craft 2 × Coarse Fabric.
• Craft 1 × Rope.
• Craft 1 × Torn Sailcloth Bag from those components.

Equipping the Bag

Backpacks in Windrose are treated as accessories. To equip the Torn Sailcloth Bag:

• Open Inventory (Tab on keyboard).
• Locate the Bag slot in the character panel.
• Drag the Torn Sailcloth Bag into that slot, or highlight it and use the equip button.

Once equipped, the bag increases your available backpack slots by +4. The hotbar (quick slots) remains separate and unchanged at this stage.

Step 3 – Upgrade to Workbench Level 2 and Craft the Sailor Backpack

The next significant jump in inventory capacity is the Sailor Backpack. This requires a Level 2 Workbench and a few more involved materials, but the payoff is substantial: moving from the Torn Sailcloth Bag to the Sailor Backpack represents roughly a doubling of total extra space over base, depending on the exact patch version.

Unlocking Workbench Level 2

To reach Workbench Level 2, you must:

• Build a Sawhorse near the workbench.
• Acquire enough Copper Ingots to fund the upgrade (commonly 10 ingots, from about 40 Copper Ore).
• Use the workbench upgrade interface while both the workbench and Sawhorse are inside the same bonfire radius.

This links inventory expansion to basic progression: if you are mining and smelting copper for tools or early base upgrades, you are already on the path to better backpacks.

Mining and Smelting Copper

Copper Ore nodes are typically marked with a small pickaxe icon on the map, most commonly in a northern mine area on the starter island.

• Craft a Pickaxe at your workbench if you do not already have one.
• Travel to the nearest Copper node cluster.
• Mine nodes until you have at least 40 Copper Ore (more if planning for weapons, tools, or building pieces).
• Return to base and smelt Ore into Copper Ingots at a Furnace.

Once the workbench is upgraded to Level 2, the Sailor Backpack recipe becomes available.

Materials for the Sailor Backpack

The standard Sailor Backpack recipe at Workbench Level 2 is:

• 1 × Torn Sailcloth Bag (your existing bag)
• 2 × Copper Ingots
• 5 × Rough Hide

Rough Hide is primarily obtained from boars and wolves, especially in the Coastal Jungle and similar early zones:

• Equip a basic melee weapon or bow.
• Hunt boars in the jungle or forest edges.
• Loot Rough Hide from their corpses alongside meat and bones.

In co-op, assigning one player to continuous hunting while another focuses on mining accelerates this stage considerably, since hides and ingots are both required.

Crafting and Equipping the Sailor Backpack

At the Level 2 Workbench:

• Open the crafting menu.
• Locate the Sailor Backpack under the relevant category (usually Accessories / Bags).
• Ensure your Torn Sailcloth Bag is in your inventory (not equipped on the character) if the recipe requires it as an ingredient.
• Craft the Sailor Backpack.

Then, in the inventory screen:

• Unequip the old bag if it did not get consumed automatically.
• Equip the Sailor Backpack in the Bag slot.

At this point, your total backpack capacity increases again. Different early-access builds have reported slightly different slot numbers for this bag (some list it as providing +8 total over base, others as a step in a +4-per-tier chain), but in all cases it is a clear upgrade over the Torn Sailcloth Bag and is the practical goal before serious exploration.

Later Backpacks: Bosun and Quartermaster (Higher-Tier Options)

Beyond the Sailor Backpack, community documentation and early guides reference at least two higher-tier bags:

• Bosun Backpack – crafted at a Level 3 Workbench, typically encountered when progressing into the Foothills zone; requires the Sailor Backpack as a component.
• Quartermaster Backpack – associated with later-game regions such as the Cursed Swamp, also tied to higher workbench tiers.

The broad pattern reported by players is that each successive backpack tier increases capacity in roughly +4 slot increments over the previous tier. Exact numbers and recipes may vary slightly across patches, and official patch notes are limited. For planning purposes, treat each new bag as another step up in carrying capacity and assume it will require:

• The previous backpack as an ingredient.
• Zone-appropriate refined metals (e.g., more Copper or later-game ores).
• Tier-appropriate hides or advanced materials from stronger wildlife.

Because of the uncertainty in slot counts for the Bosun and Quartermaster backpacks in post-early-access builds, it is safer to plan around what is confirmed: Torn Sailcloth Bag and Sailor Backpack are always available and always meaningful upgrades.

Supplementary Storage: Chests, Labels, and Ship Cargo

Backpack upgrades alone are not enough to solve Windrose’s inventory pressure. The game expects players to use external storage aggressively.

Base Chests and Organization

Early on, craft several Wooden Chests at the workbench and place them around your bonfire. Then:

• Assign one resource type per chest where possible (e.g., ore and bars in one, wood and plant fiber in another, hides/bones in a third).
• Use Wooden Labels (nameplates) if available to mark each chest’s contents.
• Take advantage of any quick deposit feature to auto-transfer items that match existing contents into the appropriate chests.

This reduces overlap and makes later crafting sessions faster because you know exactly where each resource type is stored.

Ship Storage

Once the main story pushes you toward shipbuilding (often around the “I Need a Bigger Boat” stage), your Ketch or other ship introduces additional storage. This is especially important for long expeditions between islands.

• Reserve ship storage for expedition-critical supplies: repair materials, spare weapons, food, and region-specific tools.
• Keep bulk crafting resources (stone, massive wood stacks) in base chests instead; moving them by ship is rarely efficient unless relocating your base.

Combining a mid-tier backpack with a well-organized chest system and moderate ship storage is usually enough to keep inventory manageable, even though community feedback often describes the overall limits as tight.

Efficient Material Farming Routes

Because inventory is limited, the goal is not only to carry more, but also to carry more of the right things in fewer trips. A few practical loops help here.

Fiber–Wood–Food Starter Loop

Near the starting area, set up a short loop that hits:

• Several shrubs for Plant Fiber.
• A few nearby trees for Wood.
• Low-level wildlife or berry bushes for Food.

This produces the raw materials for your initial Torn Sailcloth Bag, basic tools, and early cooking without overwhelming the small base inventory.

Copper–Hide Mid-Game Loop

Once aiming for the Sailor Backpack, use a slightly longer loop that alternates between:

• Copper nodes in the local mine or rocky zones.
• Boar/wolf hunting grounds on the route back to base.

The objective is to arrive back at base with enough ore to keep the furnace active and enough hides to keep the workbench progression moving, without filling the bag with lower-priority junk loot. Discard or ignore very low-value items (broken weapons, small-value trinkets) when space is tight.

Common Inventory Mistakes and How to Avoid Them

Several patterns repeatedly cause inventory problems even after players unlock better backpacks. These can be addressed with simple habits.

• Carrying crafting stockpiles “just in case”
  Keep large stacks of ore, wood, and fiber in chests. For excursions, bring only what is required for specific objectives (e.g., repair kits, arrows).
• Holding multiple half-broken tools
  Retire or recycle nearly broken tools at base; carrying three versions of the same pickaxe consumes valuable slots.
• Looting everything indiscriminately
  If space is limited, prioritize higher-value materials: metals, hides, unique drops. Leave low-tier junk until after you upgrade backpacks or storage further.
• Ignoring workbench placement
  If your Sawhorse or other upgrade stations sit outside bonfire range, the workbench may not register upgrades correctly. Keep all core crafting stations inside one tight cluster.
• Underusing labels and quick deposit
  Manual sorting into unlabeled chests wastes time and increases the risk of duplicate stacks. Naming chests and using auto-sort features compresses session overhead.

Practical Slot Usage and Expected Capacity

Across most documented builds, the progression looks roughly like this:

• Base inventory: 16 backpack slots + 8 quick slots.
• With Torn Sailcloth Bag: base +4 slots (early-game baseline for exploration).
• With Sailor Backpack: a further increase (commonly referenced as +8 total over base, though some sources treat it as the second +4 step).
• Later backpacks (Bosun, Quartermaster): incremental slot increases per tier, often modeled as +4 additional slots each time, but exact totals differ between early guides and later community reports.

Given the limited official data for post-early-access maximum capacity, a cautious way to plan is:

• Assume each new named backpack is a clear upgrade.
• Always craft the best bag your workbench level and zone progression allow.
• Use chests and ship storage to absorb all long-term material stockpiles.
• Reserve backpack space for tools, current quest items, and high-value resources from the zone you are actively exploring.

Combined, these steps keep Windrose’s tight inventory system functional without constant backtracking, even though the absolute number of slots remains modest by design.
