Adding a zipper to eVent bivy (in theory)

Hi Steve,

I have one mself, I would ask Ben Smith from Gooses feet could he modify it for you.

Cheers,

Thanks for the reference, I called Ben and I'm encouraged to hear that he doesn't think I've lost my mind. I'm hoping to hear from some more members before I pull the trigger on this…

Thought I'd try to clarify what I'm talking about here in hopes that folks will chime in. Also, when/if this gets done should it be taped?

The Bivy/Overbag

Where I would like the zipper to run

An issue at the top…the seam tucks under the hood and follows a line off of the outside seam. So, if the zipper stopped where I would like it to stop the the bivy would not open up, it would just be like a big pit zip!

Closer on that area…where the yellow meets the grey…

From the outside…

Nielsen Brown (blogs – do a search) had exactly the same bivvy altered by Scottish Mountain Gear over here with a side zip…..not that you'd want to send it back but you might try PMing him for some details of how it was done…?

I was thinking of doing the same things but in the end thought that with that horrible yellow colour I'd pass ;-)

I sent Nielsen a note, great to hear I'm not on uncharted ground on this one. I consider the biggest challenge to be sourcing a zipper that has just the right mix of mustard and day-glo. Wouldn't want to diminish the aesthetics of the bag! :)

Edited for spelling

I also sent an email over to the folks at Rainy Pass. I've seen the reviews for their work on here on BPL – anyone ever have them do anything like this?

I have responded to Steve’s message but for completeness I thought I would provide my response here as well.

I, like Steve, decided that a side zip was a good idea, but how? I contacted Scottish Mountain Gear
and indicated that I wanted a side zip in the bivy, I also indicated that I wanted to have a water resistant double ended zip and suggested the length (60″ in my case). The modification done by Scottish Mountain Gear were excellent and I normally use the bivy with my mid in winter.

Thanks so much for the pictures, that really really helps. Plus, to have someone who has already field tested this idea is huge. I knew that I wasn't creative enough to have been the only one to think of this!!

Looks like I'll be asking Specialty Outdoors to do this for me. http://www.specialtyoutdoors.com/about/whatis.asp. When I get it completed, I'll be sure to post pics. Thanks!

Roger, what sort of zipper is that? Is it just a DWR tape or is it sort of "vinylised"?

I always sew zipper so edge of fabric is very close to zipper teeth.

You have to actually overlap the teeth a little before it will snag.

Then there's a smaller gap where the fabric isn't for water and air to get through.

Steve I think it is a uretek zipper, vinylised.

Alright, with all that info (thanks!) my bivy is shipping off to the Pacific Northwest to Specialty Outdoors for the modification. I feel like a friend I just met is going in for surgery!

Very cool. I've been toying with this idea as well. Please post some detailed photos when you get it back.

This site has been such a help to me, I'll be happy to share pics and details.

Hi Steve,

How much are they charging you as I have one and might get it done.

Cheers,

Stephen

Sounds like the range is going to be $45-60 for the waterproof zip. For a "standard" zip it was in the $30-45 range. I'll let you all know how it goes…

Cheers Steve, I eagerly await your report.

Hi Steve,

How did you get getting the zip added?

I was using mine on a trip last month and could of done with the zip.
