Anyone making custom footprints?

You can make a custom footprint out of a large piece of polycryo. Gossamer gear sells large sheets pretty cheap. I’ve set DCF down on the ground and been able to feel the spines of oak leaves poking right through with light hand pressure. I used polycryo under my tent for 1200 miles of the PCT before I noticed a hole and then I just put a bit of packing tape on it and was good to go.

Are you looking to do a Fly/Footprint pitch, or just protect the bottom of your tent? Your desire for grommets makes me guess the first thing, but then you commented on the weight – which grommets will contribute to.

Thanks guys..looking for the fly/ footprint option

I’ll second Diane’s suggestion on the polycro. especially if you go with the medium weight 1 mil from Gossamergear. Most people use the .7 mil underneath their shelter and it weighs about 0.5 oz / sq yd. The 1 mil on the other hand comes in at 0.7 oz/sq yd and it provides you a little more thickness (and substance) for taping on plastic washers with clear Scotch packaging tape, or QUALITY duct tape. That serves as your grommets.

Some DIY’ers use the heavier 1.5 mil Duck brand polycro to make tarps, but that’s overkill for a groundsheet. David Gardner has some threads on making polycro tarps, I’ll see if I can dig one up. He shows how the washers are applied.

You want the Large GG polycro (1 mil). Why waste money on expensive DCF?

I don’t think polycro will reliably support a freestanding tent in Fly/Footprint setup, as grommets will need to be added to support the fly poles, and I don’t think the polycro itself would hold the tension exerted by the poles for any extended time. You could use corsage to connect/keep tension in the absence of a footprint, but it might be a little finicky to set up. It would be reliable tho, and super ultralight weight. If I didn’t have a bunch of projects taking my time right now, I’d volunteer to help you out. Most footprints are a bit heavier than they need to be for people who are careful with their gear. I wouldn’t use dyneema, but a nice durable poly with a good PU coating would keep your butt dry and hold up for a good while. What tent?

You’re right Micheal, I didn’t realize the OP was referring to a footprint that involves poles exerting lateral tension, in fast fly mode. So I’d go with the Xenon 1.1 silpoly from Dutchware. It tests at a high HH and since it’s polyester it won’t retain as much water as silnylon. You can buy grommet kits about anywhere.

Consider doing tie outs instead of  grommets.  Grommets require pretty precise placement.  The tie outs are adjustable.  These are 2 footprints I made for my XMid. 

Thanks again…all good suggestions

I think that could work, but I think fast fly, or Fly/Footprint setups with freestanding shelters do in fact require some precision in locating the grommet, or in your case, tie outs, since the shelter poles require precise placement in order for the fly to pitch tightly as intended. There might be a little wiggle room, but not to the same extent afforded by non-freestanding shelters such as pyramids – you could call the tie-outs “adustable”, but it is likely that they will be adjusted once to ensure the tent pitches tight, and then left that way. Just some food for thought.
