Quiksilver Marathon Sessions

Neoprene and Liners

The Marathon Sessions is constructed out of StretchFlight eco neoprene. This neoprene is buttery and flexible. The flexibility will help reduce strain on your shoulders while paddling and keep your movements agile and easy. One of the cool things about this neoprene is that it is constructed using nearly all recycled materials. The Marathon Sessions heats up quickly and stays warm throughout your entire session due to the Primaloft® liner. The liner works by trapping and reusing your expended body heat on the raised portion of the liner. 


Seams and Stitching

The Quiksilver Marathon Sessions is held together by sturdy glued and blindstitched seams that allow the suit to flex and bend. The external Power seam detail helps ensure the Marathon Sessions maintain a watertight fit. You can find this same seam construction on all thicknesses of the Marathon Sessions. This particular feature stands out, considering that most suits with the liquid seam weld are nearly double the price. The wetsuit includes spot taping around the core and in critical areas to help maximize the seal and durability of the suit.


Fit and Cut

I'd say the closest-fitting wetsuit brand to Quicksilver's would be O'Neill. The suit is form-fitting and will slightly adjust to your body type. It is best to be in the correct weight range of Quicksilver's size chart, followed by height, waist, and chest. The Marathon sessions is slightly on the shorter side in the arm's and leg's, so if you're on the taller end of the size chart, make sure to go with a Tall size like ST, MT, or LT. The suit might seem hard to get on at first, but it will loosen up and become easier to get in and out of over time. A skin-tight fit is key to preventing water from leaking into empty spaces. Feel free to reach out to the Cleanline team if you have any concerns about sizing. 


Performance

Overall, the Marathon sessions performs well in cold water due to the interior liner technology and stretchy exterior fabric. This updated model is extremely flexible in the arms and shoulder area, allowing maximum mobility for paddling and pop ups. Performance is key in a wetsuit, and Quicksilver has you covered no matter the swell. 

Based on experience, we recommend the 5/4/3 for 50° F and below, the 4/3 for 50°-57° F, and the 3/2 for 57°-64° F. Compared to its little brother, the Everyday Sessions, the Marathon Sessions feels warmer due to the Primaloft® liner and Power seams. If you are surfing in water temperatures that put you on the fence of which thickness to get, the Marathon Sessions provides enough warmth to allow you to bump down. You may need more neoprene on the coldest days, but you should be alright for most days.


Value and Durability

The Marathon Sessions is a high-performing suit at a very approachable price point. The high-quality construction and technology found in the suit contribute to it holding up well with a snug fit in the long run. The external Power Seams help keep the seams watertight for longer. The sealed seams combined with the liner and smooth skin maximize the warmth of this suit. A cool part of the Marathon Sessions line is the variety of styles available. Whether you need a 3/2, 4/3, 5/4/3, or even a 4/3 hooded version, Quick has you covered.


Final Thoughts

The Marathon Sessions is an excellent choice for surfers looking for premium features without the premium price tag. Combining comfort, warmth, and performance, this suit is designed to perform in a wide range of conditions while remaining flexible enough for long sessions in the water. Whether you're paddling out before sunrise or staying out until the last wave of the day, the Marathon Sessions delivers the durability and reliability that surfers have come to expect.

What really sets this suit apart is the balance it strikes between performance and value. It offers many of the features found in higher-end models without the accompanying price tag, making it a great option for both experienced surfers and those looking to upgrade their gear.
