Customer Reviews
Great Triathlon Suit!
I got the FX Triathlon Suit and it's fantastic! The fit is perfect, super comfortable for long training sessions. I will definitely be back for more gear soon. I've already told my training buddies about SLS3!
Smooth order, good product
I purchased the Women's Triathlon Apparel, specifically the Sleeveless Tri Suit. The ordering process was straightforward on their website; I found my size easily with their guide. Shipping took about five days, which was within the timeframe stated. The suit arrived well-packaged and was exactly as described. The fabric feels durable but also breathable, and the chamois seems adequate for a sprint distance race. I haven't raced in it yet, but it feels good on a training ride. No need to contact support, so that part went smoothly. It seems like a well-made suit that should hold up.
FRT Tri Suit and Compression Socks
I ordered the FRT Tri Suit and a pair of Compression Socks. The ordering process was straightforward, and I received a confirmation email immediately. Delivery took about five days, which was within the estimated window. The suit felt true to size based on their chart, and the material seems durable for racing. The compression socks fit well too, providing good support. I had a question about washing the suit, and customer support responded to my email within 24 hours with clear instructions. Overall, a solid experience for athletic gear.
Great value on Tri Shorts
This was my first time buying from SLS3. I was looking for some good quality Triathlon Shorts that wouldn't break the bank. I found a pair in their clearance section, and with the free shipping offer, it felt like a really good deal. They fit well and the padding is comfortable for longer rides. For the price I paid, I definitely feel like I got a solid product. I'll probably check them out again next time I need something, especially if there's another sale.
Got my new Visor quickly
Needed a new Visor for running and saw SLS3. Figured I'd give them a try. Ordered it, and it showed up a few days later. It's just a visor, but it's comfy and does the job. No complaints here, pretty easy experience.
Good deal on Compression Leggings
I was looking for some new Compression Leggings and found a pretty good discount here. With the free shipping since my order was over $50, it felt like a smart purchase. I always try to find the best value, and this checked that box. The quality seems decent for the price I paid, so I'm happy with the overall value.
Decent Compression Leggings
Ordered Compression Leggings. They fit well. Shipping was average. Quality seems good so far. Would buy again.
Good suit, shipping a bit slow
I bought the FX Triathlon Suit for an upcoming race. The suit itself is really comfortable and feels like good quality, definitely comparable to some higher-priced brands I've tried. It fit true to size based on their chart. My only minor issue was the shipping; it took a full week to get to me, which felt a little long compared to other online stores. Customer service was helpful when I asked about the tracking though. Overall, I'm happy with the purchase and the value, just wish delivery was a touch faster.
Good running shorts
I snagged some Running Shorts from here, and they're pretty good. The material feels nice, not too thick or thin. They got to me pretty quick, like four days after I ordered them. I wore them on a long run, and they held up well. No complaints, felt like a good buy. I'd probably grab another pair if they had a sale.
Consistent quality, reliable service
I've ordered from SLS3 several times over the past few years for my triathlon gear. This last purchase was a pair of their Compression Socks, and they arrived right on schedule, just like all my previous orders. The quality is always what I expect; good compression without being too tight, and they hold up well through training and races. I keep coming back because I know I'm going to get a good product and decent delivery every time. It's nice not to have to worry about the order once it's placed.

hey, trying to figure out sizing for their tri suits. do they run small or true to size usually? i'm kinda between sizes on other brands.
anyone got a first order discount code they're not using? trying to save a few bucks on some compression socks.
can you stack coupon codes on SLS3? I have a first-time buyer one and maybe saw something else.
do they ever do free shipping on smaller orders? want a race belt but don't need much else right now.
Are these guys legit? Like, the prices seem good but I just wanna make sure it's not some weird knock-off stuff.
