    Thatís good to hear, Kathy. Customer service at TB is really great, so I am not surprised at all. They are all really helpful.

    Hello All. This is Kathy, the originator of this thread. I am typing this in a bit of rush right now as I have other things to tend to this morning, and I will be back later to provide a more thorough update about my bag. I just wanted to get this out there ASAP, though, that Darcy has been amazing with me and significant progress has been made in addressing the marks on my bag. I couldn't be happier with TB's excellent customer service! More later . . . Thanks Darcy!


    Back Now With My Update:

    Last night I followed Darcy's suggestion to try to clean the marks off my Synapse using a wash cloth and warm soap and water. While I had tried previously to wash the marks off, I had just very lightly rubbed with a damp, smooth/soft sponge and a little liquid hand soap, to no avail. Last night I made a solution of Dawn dishwashing liquid and warm water and scrubbed with a wash cloth using a bit more elbow grease than I did the first time. I repeated the scrubbing process twice last night. One of the marks came completely off and the others, while still present on the bag, are noticeably more faint. So Darcy is quite correct that the fabric itself is not damaged by wear (as I had initially thought). How well I can see the marks that are remaining on my bag is dependent on the light and the angle from which I view the bag. While I'm ok with keeping my current bag, I was a bit concerned that I'd have to keep removing marks from it as I continue to use it, and so at Darcy's suggestion I'll be returning it for a replacement. This way also TB can use the bag to try to figure out how to completely remove the marks and work with other bags that may develop this same issue. I'll also be keeping Darcy updated as to whether the replacement bag develops the same issue as I use it.

    One more time, I want to give a BIG SHOUT OUT to Darcy and TB! I really wasn't expecting this outcome when I started this thread. TB ROCKS and I can't say enough good things about them! Great products and amazing customer service! Thank you!

    Iím pretty sure what weíre seeing here is very small areas of the DWR (Durable Water Repellent) surface treatment (the water repellant stuff thatís applied to the top of the fabric) turning white-ish after being abraded ó not the fabric, but the DWR. Thatís why itís white-ish, and thatís why some (but not all) have reported success using a warm wash cloth or a brush to remove the small area of the abraded DWR. One of the folks who posted in this thread who we have been talking with via email had success using the warm wash cloth method; another will try it and let us know how it works.

    (The exception would be BrendaHís 210d bag ó the fabric on their bag actually looks abraded, so we will be working with them to figure out how that happened. It is worth noting that while 210d is very abrasion resistant, itís not infallible, and it is not as abrasion resistant as 525d; thatís why we offer bags that may see light use or can be used as packing cubes or other interior organization bags with an exterior of 210d, but we donít offer bags like the Synapse or Tri-Star in 210d.)

    This came up previously, and I think one or two people reported this to us. We contacted our fabric mill and they thought the issue might be this: the industry is changing over to the more environmentally friendly C6 DWRs, because it's a good thing to do and... the old school chemicals are going to be illegal soon. These new water-repellent treatments, so far, perform very well ó but not quite as well ó as the old school chemicals, and our mill thought perhaps they were applying too much of the new stuff to make up for that. After that, our mill tested various lower concentrations of the DWR to ensure it was still doing its job with water repellency but wasnít so thick it would appear visible when the bag came into contact with rough objects; they found a concentration that met their requirements as well as ours, tested it, and we approved. This was back in 2018. Thinking back to then, this was something we wanted to improve but didnít consider a defect or problem ó the small areas that got whiteish marks didnít significantly impact the water-repellency of the bag and were difficult to see in most lighting situations, unless one was looking for them, and they seemed to be able to be wiped off.

    If anyone is experiencing this issue, our recommendations are:

    First, try taking a soft brush or a dry wash cloth and try lightly brushing the small area of white coating off ó like one might brush a quality loafer to remove debris before polishing.

    If that doesnít help, take a warm wash cloth and a little bit of dish soap and wipe/rub the affected area.

    Weíll also be working on some in-house tests to try to find other ways to remove the DWR markoff. First, we need to replicate it ó oddly enough, we don't see this issue on any of our bags.

    Do you guys remember this thread: https://forums.tombihn.com/general-b...tle-spots.html We ended up using Citra-Solv to clean the Nikwax spots off the Founderís Briefcase; weíre going to test that in-house if we can replicate the DWR markoff and see if that works too. To be clear, though, we have not seen any 525d bags that look anything like that Founderís Briefcase!

    Weíre testing, researching, talking with our fabric suppliers and leaving no stone unturned here ó I will post more news when I have some.



    Weíve long noted that Halcyon hides imperfections more than any other fabric we use ó whether thatís 1050d, 420d Parapack, 525d, etc. We think thatís because of the two grid patterns Halcyon has ó the background diamond grid in the nylon and then, of course, the grid of the UHMWPE. Further, because the UHMWPE is white, it attracts the eye and helps to guide our perceptions away from any imperfections in the base nylon.

    Additionally, lighter color fabrics are always going to be prone to stains or discoloration (thinking of you, my now perfectly imperfect light grey sweater, but those tacos were sure good!) but the nylon diamond grid + UHMWPE white grid in Halcyon helps to mask stains. So, thatís why weíre more willing to choose lighter colors in Halcyon ó plus, the UHMWPE white grid makes most of the nylon base colors look even lighter than they actually are. And here Iím digressing way too much, but we considered offering an off-white Halcyon at one pointÖ. but then decided against it because that quality of the UHMWPE white grid attracting the eye away from stains or dirt wouldnít really be working its magic anymore Smilie
    Thanks @darcy, I hope the pics I sent to you were useful. I have a question about the DWP coating. When I noticed the marks on my Dawn Travel Cubelet I also noticed that water was absorbed into it in long line patterns. Like, wicking into the fabric. Should water be beading off? From other comments I have seen about Halcyon vs Ballistic Shop bags, I thought that lack of beading was to be expected but now I am not sure. Thanks very much for your attention.

    Oh, I've seen the same thing (or something similar) with my Canyon (210d) shop bag. Like you, I thought it was normal for that fabric, but now I'm wondering!
