Every undershirt accessory in Palworld — the Heat, Thermal, and Multiclimate resist lines with their +1 and +2 tiers, and the endgame Explosion-Resistant Undershirt that nullifies explosion damage entirely.

Undershirts are the accessory slot's answer to weather — a resist layer you wear under everything, so your armor choice stops being dictated by the climate. There are three craftable resist lines with upgrade tiers, plus one endgame oddity that shuts down an entire damage type. Here's the full set and where each piece comes from.

## The Three Resist Lines

Each line covers a climate and comes in three strengths — the base craft, then +1 and +2 versions whose official descriptions step up from slightly raises to raises to greatly raises the resistance. The Multiclimate line is the traveler's pick, covering heat and cold on one accessory at once:

| Undershirt | Covers | Base Recipe |
| --- | --- | --- |
| [Heat Resistant Undershirt](https://palworld-db.com/item/Accessory_HeatResist_1) | Heat | 20 [Wool](https://palworld-db.com/item/Wool), 15 [Flame Organ](https://palworld-db.com/item/FireOrgan), 25 Leather, 35 Fiber |
| [Thermal Undershirt](https://palworld-db.com/item/Accessory_CoolResist_1) | Cold | 20 [Wool](https://palworld-db.com/item/Wool), 15 [Ice Organ](https://palworld-db.com/item/IceOrgan), 25 Leather, 10 Cloth |
| [Multiclimate Undershirt](https://palworld-db.com/item/Accessory_HeatColdResist_1) | Heat + Cold | 40 High Quality Cloth, 20 [Flame Organ](https://palworld-db.com/item/FireOrgan), 20 [Ice Organ](https://palworld-db.com/item/IceOrgan), 20 Polymer |

The +1 and +2 tiers have no standing recipe — they come through **schematics found in treasure chests**, the same loot family the [legendary schematic guide](https://palworld-db.com/guides/best-legendary-schematics) farms. Each schematic sits in your inventory and unlocks the stronger craft, so a lucky chest permanently upgrades the line.

## The Explosion-Resistant Undershirt

The fourth undershirt ignores weather entirely: the official description says it **nullifies damage from explosions** — not reduces, nullifies. The recipe is pure endgame: 10 [Explosion-Resistant Fiber](https://palworld-db.com/item/UniqueMaterial_Mothman) and 50 [Mythical Wood](https://palworld-db.com/item/Wood_WorldTree). The fiber has exactly one source — the boss [Silvance](https://palworld-db.com/pal/silvance) drops a guaranteed 5 to 10 per kill, so two takedowns fund the craft. Against rocket-happy endgame enemies and raid bosses with blast attacks, it's a genuinely build-defining slot.

## When to Wear Which

The practical rules:
- Wearing climate armor already? The undershirt slot frees you to pick armor for stats instead — the [armor guide](https://palworld-db.com/guides/best-armor-by-tech-level)'s base versions plus a matching undershirt beats carrying three armor sets
- Heading somewhere with both extremes (volcano days, frozen nights), the Multiclimate line covers the swing on one slot
- Once Silvance is farmable, the Explosion-Resistant shirt becomes the default for boss content — weather is survivable, rockets are not

The rest of the accessory family — [talismans](https://palworld-db.com/guides/all-pal-talismans), [rings](https://palworld-db.com/guides/all-pal-rings), [batons](https://palworld-db.com/guides/all-pal-batons), and [charms](https://palworld-db.com/guides/all-charm-locations) — covers the offensive half of the slots.

> **Tip.** Flame and Ice Organs gate the base crafts, and both farm fastest with a matching [drop booster](https://palworld-db.com/guides/best-support-pals) in the party — a Penking run for Flame Organs or a Faleris run for Ice Organs stocks a whole wardrobe of undershirts in one trip.
