Suggestions for a light weight alternative to Slops/venetians

[RowenD]

  I started on a set of paned slops using the MA pattern last weekend.  After cutting out the pattern, and assembling  the trunkhose, lining and underlayment, hubby took one look at them and proclaimed them too hot to wear.  This, even after I left off three of the 7 layers and eschewed the interlining *sigh*.  This project will remain unfinished (for now).   I have to admit we both roasted last year in 80 degree weather.   
  Hubby still  needs a decent looking substitute for the black velvet  (lining, interlining and velveteen) Venetians he wore last year and roasted in. 
  I'm thinking maybe a pair of unlined Venetians in dark gold cotton drill, to be worn over his favorite bike pants.
  It needs to go with his black velvet/fleur with gold piping doublet which is pretty detailed.  I'm afraid the plain fabric will look odd next to all that pattern.

You don't have to do a million layers - a simple pair of "pumpkin pants" that are unlined will work well.   Really, you loose a lot of heat from your head and neck area (heat goes up!) so what he'll want to do is wear the doublet open.   

You can also use black linen as well but I think the wool (I know, wool sounds "warm" but tropical weight wool is quite breezy) would look better.

 I'm thinking linen too, but he doesn't want to wear black.

I don't make slops with more than two solid layers. If they are paned, I make the Inner lining of cotton, a outer layer of silk and then the panes are completely seperate pieces that are open.
I think he will be ok with the doublet open, but black does tend to absorb heat.

My entire costume is black, and it is not as hot as you'd think. Even in the summer. Really.

What is his doublet made out of?  It looks like man-made fibers from the photo - which would explain a lot of why he is worried about being hot.  Polyester, acrylic, and acetate are all like wearing a plastic bag in the summer - and it's not fun.   Given that it's the chest/shoulders/neck area where you lose heat from, I'd suggest considering making a new doublet out of natural fibers like linen or tropical weight wool.  Even silk might be preferable to man-made fibers.   

Tan tropical weight wool for the Venetians would work for this doublet.  However, I, unfortunately, think the real culprit in this problem is the doublet itself.

  The doublet is home dec fabric  and velveteen, and  yeah, it's hot.
  I compensated somewhat by making the side seams laced so he can ventilate without opening the doublet front. The Venetians that go with this are velveteen with matching dec fabric at waist and cuffs.
   Looks good but it's at least as hot as my outfit, though at least I have my legs uncovered under the hoop, and the bodice is the only really 'fitted' piece to go over the corset.   
   After discussing this last night, he is willing to go with a lightweight set of pumpkin pants without panes.  It will have to have 2 layers since the inner lining is what supports the outer layer in the 'pouf' shape. I hope to convince him that linen in black will work.
   You can see both outfits in my old avatar.

I hope you post photos when you are done.
Have you considered 'slashing' the doublet?
If you have a buttonhole attachment you could make the long buttonholes and have ventilation without a lot of frayed edges.
