I have a couple of those braided carriers similar to what Jeff made Snowman.
Mine were made several years ago by a former HOB here, "guywildstorm" aka Guy Clark, out in Colorado.
Don't know if he's still even on the forum.
I do know Jeff's work is just as top-notch...if his drags are anything as good as his lanyards.
And Jeff's prices won't break the bank either.
If you're a DIY, and really have a super-tight budget......
You can go to the hardware store & buy a 3ft-4ft piece of 1-1/2" or 2" wide, flat nylon strapping. (per how ever many drags/carrying straps you want)
Once home, singe the ends of the straps.
Then tie a slipknot in both ends, to slip around feet/teeth/whatever.
I've got a gouple of these that I made myself years ago, & they work well.
Not pretty to look at, but dead critters aren't concerned with looks. Hahahaha
I also have used a "deer drag" in the past, if I didn't feel like carrying the critter.
I don't know if anyone still makes them, as I've had mine for about 20 years.
It's a big 2" wide loop strap, that you can either throw over your shoulder (or across your chest) like a harness/sling.
It has a nylon rope tied to it that's about 6' long.
Below is a link to a pic of one.
