Someone at bikeforums pointed me over here when I asked about this there so maybe y'all can help.
 
Basically is riding a bent with a euromesh seat for an hour and a half or so in hot weather something to completely avoid or it is better/worse then a diamondframe(upright?)?  
 
I need to carry at a minimum clean bib/jersey(or equivelent bent riding clothing) for the ride home, shirt/pants/... for work, cell. They ordered a brainbag for me but didn't have really any bags so I am not sure it'll fit. Right now winter clothes are a tight fit in my supposed 1,480 cubic inches bag.
 
Currently I commute 42 miles round trip 3-5 days a week from Double Oak to Irving. Mostly on an Old Merlin Road or a Fuji Touring Xtracycle. I ordered a Giro 26 with fenders and such a few months ago and it is still "yet to be built" because I need a large and sometime in february is when they start making larges (as of december anyhow). Buying it mostly for perhaps lower HR, ease on joints/tendons and such (I have a connective tissue disorder) and a different workout then an upright.
 
Years ago I rode a BikeE CT on my commute in nice weather back to commute in connecticut but when it was hot the seat back bag caused heat rash. The bag insulated my back and trapped all the heat between it and my back like I was sitting on leather or something.
Now I have to deal with TX heat though, been here going on 4 years now. I was riding last year on my Fuji 20 miles or so roundtrip and even in the hottest part of the day it was ok. I got one of those bandanas with the gel that absorbs water and it really helped out but with my back covered I'm really not sure.

I see you made it - welcome!
 
It's hard to bike on anything in the heat, and there will definitely be some sweating.  I imagine it will be worse than a df since your back is pressed against something.  Youi mentioned it causing a rash - have you thought it might be the kind of shirts you wore or the laundry detergent or soap you use?  Do you wear breatheable clothing?

I ride a hardshell with a closed cell foam pad (really old school RANS) and I hardly ever have a problem as long as I use a wicking shirt, take breaks, and don't wear the same jersey two days in a row without washing. I did try wearing a T-shirt a couple of times and that didn't do so good.
 
But then again, I'm not like other people. I ride 56 miles each way just to have lunch with a friend.

I agree with Steve (aka the infamous "Strada 177" for his IQ).  I live in Flower Mound and ride a bent (Bacchetta Aero), with a carbon seat and Ventisit pad.  While there is absolutely no airflow through the cabon seat, the Ventisit pad is much better than the standard foam pad.  
 
Quite a few of us bent riders participate in ultra events, often in the 10 plus hour range.   Personally, I think it's a matter of adaption.   I also have several DF bikes, and IMHO neither style makes it easier to ride in the summer heat.  
 
I'll be on my Aero tomorrow morning in the Flower Mound, Double Oak, Argyle area in case you're out riding. Keep tuned to this forum as there are a lot of formal and informal rides posted here.    

I wonder if my 08 giro 26 will get a euromesh II or if they aren't ready yet and I'll get a euromesh I.  
Thanks for the info on the pad that ventish pad sure looks to have more airflow. Does it have enough support for a heavier rider? (200+) I wrote the company and will see what they have to say but wondered if anyone here might  have an idea if I might pancake it or not.
 
I'll probably be out tommorow trying to get my fuji back running well to possibly ride down with the west end sunday superbowl ride.http://www.greaterdallasbicyclists.com/specialevents/westend.html
Here is the fuji you can't miss it  

 
My road bike is back in the shop because of an old tapped in bearing bottom bracket with no retainer device problem. Bluebonnet is going to talk to merlin about it and possibly epoxy the races in so it stops sliding out to the right. My bikeE died a cracked seat broken chain stay death so until I get the Giro I'm down to the utility bike.
 
 
 

No known rosacia. I do have some pigment problems on my whole torso kinda like this splotchwork pigment no pigment thing going on so maybe that and whatever makes me me means I get heat rash easily.
When I ride on the way home I will have some short breaks at some longer stoplights I hit. I'd hate to stop and walk around since well I am on a commute so I want to enjoy the ride but I gotta make decent time or the wife starts throwing the car keys at me  
 
It is good to know that the giro shouldn't have to sit out the heat completely though so that is good news.

Welcome to the gang, EV...   I'm sure you should be able to arrange to meet up with one of us that has the seatpad style you're considering.
 
I don't notice sweating too much with the RANS mesh seatback, but that's a different animal.  ON the other hand, riding that far on a commute, you're going to sweat a LITTLE bit, no?

Hi, bikerteam.  I was running a little late this morning, didn't get out of the house until 11:30.  I rode the route I described, but took a wrong turn and ended up doing an accidental metric century (62 miles).  It should have only been about 55 miles I think.  I'm not very fast, even on my Aero.  I usually pedal along at about 15mph, and my rolling average today was 14.06mph.  That was with quite a few stops and slowdowns for traffic, though.  Distance wise, my favorite rides are about 40 miles.  I like to ride out about 20, eat lunch, and then ride back home.
 
I would enjoy riding through Flower Mound with someone who knows it better.  My route today had more traffic than I prefer, and a lot of it was on rough shoulders with gravel, with cars whizzing by at over 50mph.  Flower Mound has some very pretty backroads I'm sure, but I needed to get all the way to Denton today, so I took the major routes and kept an "eagle-eye" on my rear view mirror.
