Get the stink and sweat out
This keeps my bases stink free. And clean. That’s it. Does its job.

Best wash for work out clothes!!
I’ve used a ton of different active wear washes and this is the ONLY one that actually gets it clean and doesn’t leave any stink behind and also doesn’t add a strong fragrance to cover up the stink. I use it in all of our synthetic active wear. Underwear, leggings, sports bras, workout tops, padded cycling shorts..it’s amazing! Tips: shake the bottle before each use and if you washer has the option, add an extra rinse to the end of your cycle.

I've been using Basewash on my cycling shorts. Works great cleaning residual chamois creme from the pad.

A great all-around wash for athletic clothing
If you're like me, you spend a lot on high-quality outdoor clothing, and spend a lot of time in that clothing training. This is my go-to for washing just about everything related to training, except DWR treated items and down outerwear. This does a great job of removing the stink and keeping technical wicking clothing doing what it should.

Solid Workhorse for Active Wear and Base Layers
Got a 300mL bottle to try with an assortment of gym clothes (including Dri-FIT & UA), riding breeches and synthetic base layers. Thanks to having at least one ancestor that was a Wookie, I am a hairy, sweaty beast. As a result, this usually means that my gym & sports clothing don't smell great by the time they get home. I'm happy to report that this base wash does a stand-up job of exorcising these odors and keeping them fresh and maintaining their moisture-wicking and quick-dry properties. Once this ran dry, I picked up a 1L as this has become a staple for these garments.

This stuff is great for cleaning that seasonal base layer gear. it works as intended and directed and seems to do the trick for the years I have been washing my base layers with this wash. the only "issue" I have with all the Nikwax products is the load ratio (i.e. max 6 items per load, etc.) with an active family and lots of base layers to wash, I can go through this product quickly. you wont be dissappointed.

Good product
Works great with SmartWool products. I was the driest man on the mountains today.

Great cleaner
The base wash got rid of all the soil and contaminants in my snow shell and brought back the water repellant nature of my coat, eliminating the need to use additional products.

Works great
This is a great product for cleaning your waterproof ski outerwear. I only wash my shells a few times a season, but they came out noticeably cleaner.
