G'day Alan,

Love a good Swanndri bush shirt, they're an awesome piece of kit.
The TX Direct is great for high tech synthetic fabrics with existing DWR treatment or gortex, etc.
If you're needing to revamp the shower resistance on your Swanndri, you'll be wanting Lanolin Conditioner.
Its not recommended to use anything else on their woollen bush shirts.
Hope that helps!

G'day Cara,

Yep, TX Direct will be suitable for them. Basically what the TX Direct does is help restore the DWR treatment, but it won't be able to add additional waterproofing beyond the garment's original capabilities - hope that makes sense.

G'day Peter,

It certainly would hurt, might also be worth investing in Seam Sealer to do along the inside stitch lines as well.
I would also recommend getting in touch with MSR and seeing if they can recommend a product to maybe do an internal coating on the bivy fabric.  Gear Aid do a tent sealer but I know it's not necessarily compatible with some ultralight fabrics.

G'day Margot,

The Nikwax Tent & Gear Solar Proof would be the best way to go!
The TX Direct is aimed primarily at wet weather clothing.
Hope that helps!

G'day Meg,

No, TX Direct is for lightweight Gortex style gear like tent flys and rain jackets, and gives it a light DWR coating which is not the same as waterproofing.
You're best bet would be to hand wash with some Atsko Sport Wash, and use a waterproofing spray such as Silicone Water Guard afterward.

G'day Emma,

TX Direct Wash In Waterproofer is designed to replenish the DWR coating on a water-proof breathable item (like Gore-Tex). Based on your description it doesn't sound like the polyester puffa jackets have any water repellancy, so this product won't really help. We'd recommend a Silicone-based waterproofing spray to make the kids jackets water repellant.

G'day Sue,

Thanks for picking that up for us! I've just double checked the Nikwax TX Direct Wash In Waterproofer for you and it needs about 100ml per garment, so you'll get 3 garments waterproofed with one bottle.
