Customer Reviews
Good deal on a Tri Suit
I was looking for a new triathlon suit and saw SLS3 had a clearance sale. I snagged an FX Triathlon Suit for a really good price, almost 40% off. Shipping was free because my order was over $50, which helped a lot. The suit itself feels like good quality, especially for what I paid. Felt like a solid purchase.
Decent suit, slow shipping
I ordered the FRT Tri Suit and it's pretty comfortable for long rides and runs. The material feels durable, and the fit was true to size based on their chart. My only minor gripe was the shipping time; it took about 7 days to reach me in California, which felt a bit long. Customer service was responsive when I asked about the tracking though. Overall, a good suit for the price point, but I wish delivery was faster.
Needed a Visor, got one!
So I needed a new visor for my runs, my old one was pretty worn out. Decided to check out SLS3 since a friend mentioned them. Found a simple Visor and just grabbed it. It arrived pretty quick, like in 4 or 5 days, which was cool. It's comfy, keeps the sun out of my eyes, and doesn't feel flimsy. Pretty happy with it, honestly. No complaints, just a good basic visor that does what it's supposed to.
Always reliable for gear
This isn't my first time buying from SLS3. I've gotten a few pairs of their Compression Socks before, and this time I picked up some Cycling Bibs and a matching Cycling Jersey. Just like last time, the quality is consistent. Everything arrived well-packaged and the fit of the bibs was great for my longer training rides. I keep coming back because I know what to expect, and their gear holds up well over time. It's nice to find a brand that doesn't change their sizing or quality every season. Their stuff just works.
Triathlon Shorts worked well
Got some Triathlon Shorts. They fit right. Comfortable for my training. Shipping was okay, took about 5 days. No issues with the order. Happy with them.

Share tips, ask questions & help fellow shoppers save more
Do they ever have sales beyond the occasional 10-15% off? Waiting for a bigger discount on a new suit.
Thinking of grabbing one of those FX suits. How long does shipping usually take to California? Need it before a race.
Are these guys legit? Like, is it a real brand or some random aliexpress dropship kind of deal?
How does SLS3 compression socks compare to 2XU? Is it worth switching or should I stick with what I know?
Hey, anyone know how the SLS3 tri suits run size-wise? I'm usually a medium but sometimes brands are way off.
