So I'm thinking of making a karo step down jacket and have a few questions before i begin. I've looked at previous threads about this subject and the idea of where to get a pattern.
I'm looking for about 1-1.5 inches of loft and i don't think i'm looking for something as lofty as the thru-hiker kit. I think 3 oz of down should be good. Although the kit does look good since i've heard the pattern are extremely easy to follow. What i'm thinking of it finding a pattern for a basic jacket (ie. fleece or maybe the shelby windshirt pattern) and modifying it by adding a second layer since it's down.
Now my questions:
what should the baffle height be if i'm doing a karo step?
Is it possible to do a sew through karo step?
Am i better off doing something like a 1/2 inch baffle height?
Should i just get the thru-hiker whitney kit and do half the down and make 2 jackets?
If i do use a modified windshirt pattern should i size up since the down will take up space and make the jacket feel smaller?

im no pro so take everything with a grain of organic sea salt
sewn through karo i would do 6×6 on the body 5×5 or 5×4 " the long sides running parallel with the sleeve" on the sleeves when doing the karo baffles i would leave 1 inch on each side of the stitch. so only 3 inches of stitching with 1.5 inch each side un stitched. size up if using a wind shirt pattern mcalls has some good pullover and jacket patterns.
also i'd shoot Tim Marshell a pm. I know he was planing on something similarNov 8, 2011 at 9:41 am #1799726
I made the thruhiker jacket last winter. Very great pattern and instruction booklet, I highly recommend it. I would do sew through baffles with your estimated loft. I would also think you are spot on with 3 oz of down. The pattern comes with 5.something and you can buy an extra .5 oz of down to basically bring it to 6 oz. I have 3" loft around the body and 1" around the arms and head (I added a hood which was why I ordered the extra .5 oz of down, should have put this in here the first time). About 2-2.5" if you averaged it out is what their website says. I would either shoot Tim and enlightened equipment an email or pm about karo step clothing. There was a thread a few months ago with great detail about karo step. I believe he was going to try a jacket, I am about to try it with a pair of pants based on that thread. I have no clue if he made his jacket yet, but my pants won't be done for 2-3 weeks and they won't get decent testing for about 2 months.
Good luck if you try it, and post how it goes.
I would start by finding the MYOG thread from a few months ago with detail about karo step.Nov 8, 2011 at 10:08 am #1799736
you order a link to another thread I started? " i start way to many haha" Well anyway here it isNov 8, 2011 at 10:13 am #1799740
yours was a good one too. Both got me thinking about doing something Karo. I am going to do a quilt and pants karo step in the coming weeks when my down gets here…Nov 8, 2011 at 10:21 am #1799743
i recently did a quilt with differential baffling " totally made that phrase up maybe it will catch on" in essence its normal baffles from the hip up, then there is two 4inch baffles running along the side vertically , and from the hip down its karo. down is completely shiftable throughout the whole quilt heres a crappy pic from my iphone
able throughout the whole quiltNov 8, 2011 at 10:23 am #1799745
Can you take better pictures please? Are your top baffles not sew-thru so that it will be warmer around your core and lighter at the feet?Nov 8, 2011 at 12:37 pm #1799788
I'll get some better pics tonight. Yes the torso area has 2inch cuben baffles that run from 4inches away from the side to the other side with a 4 inch baffle running vertically on both edges. And the footbox Is sewn through karo syleNov 8, 2011 at 2:09 pm #1799826

Does the karo step usually have a mesh baffle or is it usually sewn through? i guess since my loft will be so low i'm just better off sewing through.Nov 8, 2011 at 2:18 pm #1799830

I'm not sure 3oz of down would be enough volume to fill a jacket if you used mesh baffles. I'd sew through.
