MEMBRANE Silpoly

I decided to use this material to make a rain skirt. It worked out perfectly. Didn't have any issues sewing it, although I did use tissue paper as a backing when I first started sewing the rolled hem at the corners.

Great material

Recieved my order quickly. Used it to make a footprint for my Durston X-Mid 1, and it came out great.

The material is great, but it's not the same color as the one I ordered a couple of years ago (both Dark Olive), so I can't make a tarp from two different halves. That's to be expected, but here's a tip that when you make something, don't combine old and new :)

Kit arrived quickly, Went together well Would have liked One inch larger radius reinforcement patches and more of them, Made my own, but the supplied material worked much better. The 3/4 inch grosgrain material was too large for the supplied 1/2 inch plastic hardware. I had not planned on using it so no big deal. I purchased thread thread which would not work in my sewing machine. Took me a while to figure that out, actually my wife did. I have used their thread before without a problem so not sure what was different.
I contacted them but have not heard back. All in all I would do it again. Material has withstood rain well and was easy to work with..

The end result was great! In general I was hoping the directions would have been easier to follow, but all in all, it worked out well. With my configuration it ended weighing 16 oz with all required cordage and stuff sack.

Every time I order material from them it comes super fast, exactly how I ordered, and is extremely high quality. This membrane silpoly is so lightweight and packable, yet very easy to work with. I cannot believe with a little effort you can get a 12oz, 10’x12’ tarp for $65. I have not tested the waterfroofing yet, but thank you RBTR for making this possible and I will update when it has been used in a rainstorm, I have complete confidence that it will hold up to whatever I put it through

My latest tent is a free standing double wishbone 2 person tent with removable rain fly. The Membrane rain fly only adds a out 8oz to the total 39.75oz total weight. It is stayed waterproof in light rain so far but I can't comment on sustained downpours. This material is easy enough to sew but being slippery makes large sections a bit of a chore to get beautiful rolled seams. Can't wait for RSBTR to get their new DIY gallery up and running. Even with submitting my projects on the Google form I have yet to see them shared.

This is the perfect material for the tarp I am making. It is wonderful to be able to order just the quantity needed. And there was a great variety of materials to choose from.

So light and soft ! It hasn't rained here in quite some time so I held it under the faucet and no water got through. Nice !

I had a cold draft in my bedroom but didnt want to put in heavy fabric. I used this and it was perfect. I sewed rings at the top and attached to my ikea rail. Prrfect. Warmer.

Nice fabric and quick shipment.

Hi I received the fabric but the samples were missing...
Tks Ana

Enjoying making my own gear for my outdoor adventures!

I made a tarp sleeve and a hammock sleeve with this material.
Since it is slippery, it is a little difficult to sew the hem.
Sewing may require some practice.
But the work that rewards the hard work is done!
Easy to compress, so pleased with the packing!

I bought it for a raincoat, but “accidentally” built a tarp for my hammock. Slippery as heck, but it’s extremely light weight and packable enough that my new (bigger) tarp compresses down to a third of the size of the original. Can’t wait to see how small a raincoat gets!

I recently started making my own gear and practiced on 2 simple hammocks before attempting the Winter 12 UL project. The result came out really good, with a few issues sewing due to setting tension on the sewing machine and the fabric not being pulled through consistently (slippery in addition to needing to put tension on it to keep the hem in the right place.) I did not cut cat curves and it tensions just fine - I like being able to seal to the ground when pitching with trekking poles like a tent. Also, definitely bond the reinforcements to the tarp, I set mine 1" in from the edge to allow enough material to double roll the outer hem. DO NOT use the eco mineral spirits if you go the GE Sil II route; make sure to have good old mineral spirits (my first attempt with eco didn't cure). Lastly, the instructions state "coming soon" for the panel pulls... STILL!!!!! I didn't put mine on for fear of messing up the middle of the panel and the lack of instructions bonding/sewing the pullouts. In summary - I'd buy this and do it again!

Using this as the bottom of our sleeping bag cover/personal bivy, version 2.0. A bit tough to sew because it is so light and slippery.

Question to RSBTR, we are planning on using the cover in the Alpine Hut System in Germany and Austria this summer. Many of the huts now require that all bedding be microwave sterilized to help prevent bed bug infestation. Is the Membrane Silpoly safe to microwave?

Thanks RSBTR!

Made a pyramid tent, excellent fabric, not that expensive, light weight

The silpoly Membrane product is a nice material with a soft feel. It would be a good choice for a rain jacket. I purchased it for a lightweight tent, but don't know if it will hold up as well as the Membrane silpoly 4000 material.

Membrane silpoly is the best. It doesn't stretch and sag when wet. A taut tarp shedds wind better than a saggy one. Bonus, the poly fabric doesn't get soggy and heavy like nylon. A nylon tarp can get soaked with even a light dew. Langiappe, Membrane has the same low stretch as polyester thread; unlike nylon it won't stretch along long hems or seams and pop the stitching.

Again...great service and product (materials). The material performed so well for the sleeping down quilt that I made for camping. Light, strong, soft and very breathable.

Great material that is a pleasure to sew. Very light weight, and as always a great experience with the RSBTR team. They are one of the reasons I get all of my material from them.

This is some of the lightest waterproof gabric i have worked with. As always it was delivered quickly and exacrly as promised.

I have used this fabric for glued reinforcements on a silpoly tarp I made, and I designed a tent I plan to make from this material. The Foliage (not to be confused with Foliage Green) is an awesome muted grey color, very natural and stealthy without feeling prepper/bushcrafty. It has a decent stretch on the bias but feel plenty strong for my design intentions. Not difficult to sew after a bit of patience and practice.

Great stuff. Made a pack cover that compresses to about the size of a golf ball

Purchased for a small, light tarp. This material is unbelievably compact and lightweight but still feels plenty strong. Awesome service and fast shipping as always!

The MEMBRANE is very lightweigt. I sewed a diy monk tarp.
