Free Sanremo Sleeveless Suit

The Castelli Men's Sleeveless Free Sanremo Suit boasts water-shedding, wind-cheating, highly ventilated functionality, and we think the advantages over a jersey/shorts pairing are obvious. In a non-wetsuit-legal swim, you need a suit that will slip through the water and won't weigh you down. On the bike, you want to be aerodynamic and limit drag-creating transitional ridges. On the run, you want to be chafe free. The skinsuit platform achieves all three.

The Sanremo was constructed from SpeedFreak ventilated fabric up top and Instadry Speed fabric across the shorts. These form-fit fabrics are fast through the water and, once you are on the bike, dry quickly. Once dry, the Velocity mesh back not only has been proven as a watt-saver in the wind tunnel, it also helps to move moisture away from the skin to keep you dry and cool. The addition of a full-length camlock zipper also aids in cooling and ventilation by opening the top of the suit like a standard bike jersey, not to mention making pit stops during ultra-endurance races speedier.

To minimize chafing, Castelli included the KISS Tri Seat Pad, a lightly padded insert that dries quickly after the swim. It's thick enough to support you during that 100-plus mile bike leg, but thin enough that you won't even feel it during the marathon. Additionally, the Free Sanremo suit is sewn with flatlock stitching and includes large back pockets to hold all of your race day nutrition.

How to Measure:
For best results, take measurements over your underwear.
Measure under your arms, around the fullest part of your chest.
Measure around your natural waistline, keeping the tape a bit loose.
Measure around the fullest part of your body at the top of your legs.
Using pants that fit well, measure the crotch seam to the bottom of the leg.

What do you think about this product?



How deep are the pockets on this suit? Are they as deep as the seam that is halfway down the rear red stripe, or do these pockets reach all the way down to the seam at the bottom of this red stripe? Thanks!

Casual competitor has stepped it up!

I've used it several times

So, I’m one of those tri-guys that has slowly been adding equipment as I progress in the sport. The price was great and the fit was true to size. Upon delivery I tried in on thinking this is just another purchase to return due to size being off. Not the case. I trained in it twice before my international distance event and had no issues with the fit, comfort or performance. May have even improved my swim time due to confidence level feeling dressed like a pro! Pleasantly surprised at quick ship, too!

Excellent Comfort

I've used it several times

Top notch tri suit, with an excellent fit. The rear pockets are just the right size in case you need to carry a couple of gels with you on the run. Tested on a half 70.3 tri and the chamois provides the right amount of comfort during the bike and becomes unnoticeable on the run. Overall, the suit fits like a glove with out any chafing issues.

Can't go wrong with a one piece

I bought this because I had been wearing two piece kits and didn't like how the shirt hems would roll up. What I like about it is there's lots of pockets, but they aren't hard to access and the stuff I put in them won't fall out. I wore it for an Olympic tri and an Ironman 70.3. The top of the zipper could use some kind of flap on the inside because it chaffed during the run on the half Ironman. For the Olympic, no chaffing.

White See-Through

Great quality product as per Castelli norm. This is not meant for every day training. Save it for race days or maybe brick workouts that you want to minimize transition time. I bought the black one in the past and bought a white one this time. The white part is nearly see through when dry. I imagine it will be almost completely see through when you are sweaty. If you have the body to pull off a see through top, go for it or maybe if you don't care that others can see what's under your top. I sent mine back.
