Adding a zip to an Event Bivy. on 08/11/2013 09:51:55 MDT Print View

Hi folks,

I have an Integral Designs Event Overbag and would like to get a half zip added to it, I am wondering is this something I could realistically try
at home or would I be better off sending away to be done.

Cheers,

Stephen

If you can add a zip... on 08/11/2013 18:49:34 MDT Print View

If you are competent at sewing a zip, then I don't see any real problem. I'd probably remove any seam seal tape (warm iron and brown paper; the reverse of my OM article on repairing waterproofs). Then open up the seam and insert the zip. You shouldn't need the extra fabric provided by the seam allowance to insert the zip, but it's always nice to have a bit of spare to play with...

I'd probably insert a placket on the upper half to protect the zip from rain; any old waterproof fabric that's to hand, folded double. Sew the placket between the outer and the zip. Probably easiest to sew the placket to one side of the zip (on the outside face of the zip...) before inserting the zip as normal.

Then tape the zip seams. There will be a small water path to the zip backer fabric via the threads of the seam, but you can always run some DWR treatment along it to help.

Cheers Captain,

Unfortunately it will have to be done by hand as my sewing machine is back in Ireland.

I will indeed check out your OM article on it.

Much appreciated.

Stephen,
Do you expect this to be waterproof when you are done?

Hi Greg,

Good question.

The overbag is purely for deep winter use in snowholes and under tarps.

If I could fit a waterproof zipper it would be a bonus, but as the event overbag does not have an enclosed hood it may be a moot point.

Stephen,

Contact Roger on these forums: http://www.backpackinglight.com/cgi-bin/backpackinglight/forums/profile.html?u=rogerb

He purchased an Overbag from me and had someone put a full zip on his...waterproof. Nice work, by the way.

Cheers Malto,

Will check Zpacks out.

Hi Dave,

I seem to recall that Roger got his done by Scottish Mountain Gear.

Cheers,

Stephen

Waterproof zip on 08/12/2013 10:13:20 MDT Print View

This might be used to replace my suggested placket (aka flap protecting the zip). But I think your logic regarding use and the big hole at the top is probably sound; how 'waterproof' do you really need it to be? You might add an internal placket, facing up, to keep out the tiny amount of water that might seep in through the seam thread. This placket would have to be fixed to the back of the zip, and the seam can be completely sealed.

Hand sewing is going to be painful, with either plackets or 'waterproof' zip.

Kevin,

I thought hand sewing might be a pain in the arse.

Hi Roger,

Do you use the bivy much in winter?

Not really, I have been using a tarp tent, but this winter it is more likely because I will partner it with an MLD Cricket

Add zipper to ToddTex bivy on 11/14/2013 14:42:21 MST Print View

I am curious about this as well. I've got a Bibler bivy made of the ToddTex fabric. It is very durable and repels weather nicely. But there is no side zipper. I'd like to add one if possible. Anyone know of a place in California? Thanks
