Warm season top quilt DIY idea

[litetrek]

I am thinking of making a warm season top quilt for temps above 50 degrees. My idea is to make something like a poncho liner quilt but lighter. If I used the lightest argon ripstop nylon and some 2.5 oz/ sq yard apex climashield the quilt could be many ounces less than a pound. My plan includes sewn through construction with baffles similar to but wider than baffles on a down quilt. I know I don't need the baffles but I want something less poofy and the stitching holds the cover in place. For those who don't know, you can go to a quilter and get stitching like a poncho liner done but I don't want to pay for that.

Anyhow, it would be great to have some estimate of what the temp rating would be. Thru hiker has a formula for effective temperature but it seems pretty high.

Can anyone give me an idea of roughly how cool a quilt like I've described might go? my goal is a quilt several ounces less than a pound that will go down to 50 degrees and not be too hot for most of the summer (75 degrees or so).

I made one exactly like that and it's good to 50 degrees. After that, you need to wear a fleece to bed.

When you say baffles...do you mean you'll put the 2 pieces of argon together, with the insulation in the middle, and sew across? Or are you sewing the 2 pieces of argon together, then putting strips of insulation in between your sewn through "baffles"?

#1 sounds fine to me. #2 not so much...

The first one. It is pretty hot in the southeast in the summer at night. My 20 degree down top quilt is too hot above about 50 degrees and I'd like to have something for the warm season. I don't want anything heavy or bulky or I would just use a piece of fleece.

Thanks. 50 degrees seemed about the limit for what I described. Thru-hiker put the effective temperature at a few degrees below 80. I don't know what effective temp is and I didn't see it defined on their webpage but i sleep comfortably down to 70 with no quilt on top so their equation really didn't help me.

You don't really need to sew any "baffles" into the quilt. At most maybe 3 spots of stitching or quilting loops. Climashield is very stable stuff, unlike primaloft.

I know. I don't like sleeping with the poofy loose nylon fabric. Stitching all the way across eliminates that for the most part. My original idea was to get it quilted like a poncho liner, but it adds cost.
