Backpacks Staining Your Shirt?

I had an original Mariposa and now a Mariposa plus custom and haven't noticed any stain problems with these packs. I've heard this complaint before though. The last hike I did carrying the Mariposa was quite warm, around 80-85deg., but I can't remember if I was wearing a light or dark shirt, either way, no stains. Although, I have sweat stains on the mesh.

Exact same thing happened to me — mariposa plus backpack, white shirt, result is something that looks akin to ink stains all over the back of the shirt.

So what? I only plan to use the shirt backpacking, so …

Ditto for the Mariposa Plus and my supplex shirt. No biggie for me either.

Wow I wouldn't like that either, especially considering the cost of Icebreaker shirts.

You might try soaking the backpack in salted water, which as best I recall is used to help set dyes. Then of course, rinse it really well.

I would probably try washing the shirt a few times to see if the dye will leach out of it. You might try rubbing bar soap into the stained shirt, scrubbing it against itself, and then rinsing, before laundering it in your normal method. If all else failed, I would probably personally consider using a light bleach solution in the washer, especially on a light colored shirt.

That's really a bummer.

Hey, thanks for all your responses and ideas. It's a "big deal" for me because:
– Icebreakaz be 'spensive.
– I want to know how I can be assured this won't happen to ALL my clothing!
– I take "multi-use" into account when buying clothing; performance clothing is expensive and I'd like to use it backpacking, dayhiking, kayaking, bike riding, skeet shooting, nerf herding…

Pamela, your suggestions were great, thanks a ton…I am most concerned about getting excess dye removed from the pad sleeves of the pack than one piece of clothing, so I will definitely give that a try. I'll also follow up with Gossamer Gear customer service and see if they have any suggestions.

I don't have any direct experience with your exact problem, but I would suggest you try a product called "Zout" – not "Shout" but "Zout". I think you can get it at Bed and Bath here in the Bay Area. It can be a bit hard to find.

I've used it to rescue many a T shirt or dress shirt from wine, blood, chocolate, oil stains, etc. Works like a miracle and might solve your immediate staining problem.

That or I believe there's a formulation of Oxy-Clean that is advertised as safe for delicates (which would cover the Icebreaker, I presume)

my dad had problems with his mariposia staining his shirt, but it wasent the black mesh sleeves, it was the orange from his therma-rest prolite 3

If you check out the product pages for the Mari/Miniposa on GG's site you'll see that they're very aware of this issue and have some info on what to do.

Have you tried laundering your shirts with bleach (Clorox)?
