[Low-Tech] Padded Cloth and Layered Armour penalty

[Rasna]

According to rules, layering armour over Padded Cloth (DR 1*) would give -1 to DX. However, the combination of metallic armour over thick padding (not so thick to work properly as standalone armour, but in any case thicker of the DR 0* padding which is included in armour stats) was so common in certain periods and regions (ex. XIII to XVI century Europe) that makes me think that the -1 DX penalty for layering armour seems to be excessive. Wearing mail armour over padded cloth isn't the same that wearing mail armour under a heavy gambeson (DR 3) or under a coat of plates. In the first case, the total weight is inferior, the distribution of weight is better and movement are less likely to be significantly hampered.

So I propose that:

1) Wearing a layer of flexible armour over a single layer of Padded Cloth shouldn't give any DX penalty. Wearing any kind of armour over a single layer of Padded Cloth which is Expertly Tailored or Masterfully Tailored shouldn't give any DX penalty. Expertly Tailored Padded Cloth and Masterfully Tailored Padded Cloth would count as Arming Doublet for the purpuose of calculating the -1 DX and -1 DR penalty for wearing a Plate armour suit without a proper underpadding.

Or, alternatively:

2) Wearing a layer of any kind of armour that isn't of Cheap Quality over a single layer of Padded Cloth shouldn't give any DX penalty. Expertly Tailored Padded Cloth and Masterfully Tailored Padded Cloth would count as Arming Doublet for the purpuose of calculating the -1 DX and -1 DR penalty for wearing a Plate armour suit without a proper underpadding.

Layering penalty is often about game balance rather than realism (donning a clamshell over reflex bodysuit causes DX penalty), so if those rules doesn't disrupt the balance of your games, then go ahead.
Regarding official stance, Dungeon Fantasy Knights has a power-up that allows them to wear armor up to DR2 without causing DX penalty.

In general the layered armor penalty is for two armor layers both designed to work independently as armor, not for two armor layers that are designed to work together -- it's just that two armor layers that are designed to work together tends to be statted up as a single suit of armor with multiple components, not as two suits of armor.

Outer armor can probably be tailored to assume an inner layer of a given thickness (this is basically the same as armor tailored for a larger individual), and wearing this without the expected inner layer would result in a DX penalty, while wearing it with would mean no penalty. There’s a limit to how thick armor can be before it physically gets in the way of movements, however - I generally assume up to 0.2” for rigid and up to 0.5” for flexible is ok (for hybrid cases, no more than 0.2” for the rigid layer and no more than 0.5” overall). Some areas (Chest, Skull) can be thicker, some areas (joints, mostly) must be thinner, of course, but that level of detail isn’t strictly necessary. That’s for a human with an average build; larger characters can wear thicker armor, smaller characters must wear thinner armor.

Usually yes, this is the case, but is possible to use Padded Cloth alone and in combination with something heavier, because it's at the same time a form of padding and a form of armour. GURPS rules penalise the conjuct use of proper armour with DR 1+ padding.

Padded Cloth is flexible and is 0.25" thick. That's why I think that the DX penalty is excessive, if the armour "layered" with Padded Cloth isn't of Cheap Quality. So I'm for decreasing the penalty from a milder form (ex. -1 only to some DX-based skills, like Fast-Draw) to no penalties at all.

I don't agree with you, Dan, at least not in game terms. Of course the point of the discussion is to take something that is real and "translate" it in GURPS stats. We can translate most historical pourpoints as being DR 0, but not the thickest of them (DR 1* to DR 2*) that were still used with some other form of armour.

GURPS DR 1* "Padded Cloth" is described as being only 1/4" (ca 0,625 cm) thick, so can be translated in something that could be 6-8 layers thick. Which was rarely worn by itself, but it can provides some protection against punches, batons, sword cuts and knife stabs, while the normal underpadding (DR 0) when alone has no protective value at all, at least in GURPS terms. So we are talking about a thick vest or a thicker-than-usual form of padding, depending on cases.

Textile standalone armour would be anything from Light Layered Cloth (DR 2*) to Proofed Paper (DR 6). The combination of a thicker-than-usual padded garment worn with mail and/or lamellar or plate armour translated in GURPS game dynamics is present in your own work, Dan: Qin Cavalry Loadout, Byzantine Skoutatos Loadout, Third Crusade European Loadout, Mamluk Heavy Cavalry Loadout and Northern Mughal Cavalry Loadout, all of them wear metallic armour over GURPS Padded Cloth.

If it's 1/4" thick, it's very tightly stitched together, as by weight it's something like 130 ounces per square yard.

I think the issue is your use of the term "Padded Cloth", which has a very specific definition in Low-Tech. The Padded Cloth armour in Low-Tech, is 1/4" thick AFTER it has been compressed with quilting. It is considerably thicker than that beforehand. This armour provides a general DR 1 vs all attacks and is too bulky to be worn under armour without application of a DX penalty. There were a lot of reasons that came up during writing and playtesting for it to be such.

The text is a little confusing because there were legacy issues with earlier issues of GURPS but the Padded Cloth armour in Low-Tech was not intended to represent aketons and other forms of arming garments that were historically worn under armour. The Loadouts book treated arming garments the same as Light Leather or Winter Clothing, which gave DR 1 vs. cutting attacks only. They won't suffer a DX penalty if specifically tailored to be worn under armour.

If nothing else if it's been significantly compressed down to 1/4" by lots of stitching, it's likely fairly rigid*

That rigidity will be an issue for layering



I think the reality is there were instances of layered armour and people taking in GURPS terms -1DX pens

(Dan Howard's Loadouts shows several examples of this)




I might be tempted to make some very specific exceptions for some combinations or armour and good tailoring

Don't forget that we're functionally talking about a -1 to relevant skill's, so you can overcome this issue by getting +1 more in the relevant skills.

If someone really wanted to have some kind of +1 to skill that only counts for negating that armour layer penalty for a specific armour set I might call that a 50%* limitation / reduction in skill cost. And a not too unrealistic way to model experienced armour wearing fighters working out how to compensate for the issues of layered armour.


Yeah OK this gets pretty damn close to a "wearing armour skill", familiarity bonus or perk, but ehh I'm OK with that


Another way to go would be to allow a +1 armour bond bonus that offsets layering penalty for individual armour sets, Same kind of justification and the individual user having just got so comfortable with the their specific armour beyond even the initial tailoring and familiarisation process. (I'd have familiarity rules for armours as well as poor tailoring issues).





*in terms of worn material even if not in terms of meeting the threshold of flexible or not in GURPS terms.


**make it -75% and it's a perk

The problem with "padded garment" is that can be translated into GURPS different things:

Ordinary Clothing: DR 0*, 1.6 lb.
Arming Doublet: DR 0*, 2 lbs.
Coat: DR 0*, 2.5 lbs.
Light Leather/Winter Clothing: DR 0* (1* vs. cutting), 4 lbs.
Heavy Coat: DR 1*, 5 lbs.
Padded Cloth: DR 1*, 6 lbs.
Light Layered Cloth: DR 2*, 12 lbs.

Arming Doublet is worn with Plate Harness. Padded Cloth is worn as helmet padding or liner. According to Dan writings here:

Something that gives DR 1* vs. cutting only is heavy as Light Leather or Winter Clothing.
If I remember well, the Tlingit Warrior Loadout includes Light Leather apron and pants worn under the armour and the combination doesn't give any DX penalty.

What if we add another thing, lighter than Padded Cloth, similar to Arming Doublet and made to interact with another layer of armour? Example:

Arming Garment: DR 0* (1* vs. cutting) when worn alone, DR 1* vs. all attacks when is worn with armour which is designed to be don with it, 4 lbs.

Arming doublets, purpoints, and aketons were no thicker or heavier than regular clothing. They were designed to stop chafing and improve the fit of the armour, not to provide extra protection. Low-Tech armour stats assume that normal clothing underneath has been replaced with an appropriate arming garment, or that the armour has its own integrated padded liner (which was a lot more common than many assume).

Wearing a layer of any kind of armour that isn't of Cheap Quality over a single layer of Padded Cloth shouldn't give any DX penalty.

Any armour worn over what Low-Tech defines as "Padded Cloth" definitely requires a DX penalty.
