Customer Reviews
Quick shipping, good fit
Ordered a pair of Compression Socks. They arrived fast. Fit was as expected. No issues.
Triathlon shorts, mostly happy
I bought the Triathlon Shorts and they were pretty comfortable for my longer rides. The material felt decent quality, and they held up well after a few washes. Shipping took about 5 days to reach me, which was okay. My only small gripe is that the sizing seemed a tiny bit off compared to other brands I've worn, so I had to really check the size chart. But once I got the right size, they worked out. Good value overall, just double-check those measurements.
Good deal on FX Tri Suit
I needed a new tri suit but didn't want to overspend. I got the FX Triathlon Suit during a sale and felt like I got good value for my money. The website had a clear section for discounts, which I appreciated. Overall, the purchase felt worth it, especially with the savings I found.

Share tips, ask questions & help fellow shoppers save more
Hey, thinking about grabbing one of their tri suits but I'm usually an awkward size. How do these typically fit compared to, say, Zoot or TYR?
Does anyone know if SLS3 usually stacks coupons? Got a newsletter sign-up code but I also found one for free shipping.
