A stretchy, neoprene-free 5/4/3mm hooded full suit built from 85% Yulex® natural rubber/15% synthetic rubber by polymer content; the natural rubber is from sources that are Forest Stewardship Council® certified by Preferred by Nature™. All internal fabrics are now made with NetPlus® postconsumer recycled nylon made from recycled fishing nets, a first in the wetsuit industry. Best for water temperatures 45°–55° F/7°–13° C. Made in a Fair Trade Certified™ factory.

Stretchy 85% Yulex® natural rubber/15% chlorine-free synthetic rubber by polymer content; the natural rubber is Forest Stewardship Council® certified by Preferred by Nature™
A first in wetsuits: All internal and external face fabrics are made with NetPlus® postconsumer recycled nylon made from recycled fishing nets to help reduce ocean plastic pollution, and solution-dyed, a process that uses no water in the dyeing process
Created by our friends at AXXE Wetsuits and refined by us, this unique U-zip design provides ease of entry and reduced flushing; constructed with a YKK® #5 stretch-coil zipper for maximum stretch and comfort and an easy-to-reach, extended custom zipper pull
Because the fit of a wetsuit is as important to your warmth as material thickness, we’ve completely redesigned all patterns for unbridled mobility, from the hood all the way down to the ankle cuff
All seams are triple-glued and blindstitched with internal stretch seam tape; linings are laminated with water-based, solvent-free AquaA® glue; external wrist and ankle rubber gaskets provide a secure fit and help prevent a blowout while dragging arm in the tube (or unforced dismount); easy-access key loop
While there are many factors that determine your warmth, this suit is recommended for temperatures between 45°–55° F/7°–13° C
Made in a Fair Trade Certified™ factory, which means the people who made this product earned a premium for their labor

Best Suit

I've been on a journey with wetsuits to find the perfect balance of warmth, comfort, stretch and durability - seems you only get to pick a couple of those options but not all until this version of Patagonia suits - I've worn the 5/4, 4/3 and 3/2 in a variety of conditions and can't say I've ever had a better suit. I was able to wear a proto UZip 5/4 all last winter - the suit is warm, stretchy, comfortable and shows little sign of wear or "blow out" like most suits after a long winter. Feeling confident that these suits have nailed the formula for warmth, stretch, comfort and multi season durability.

The UZip is a huge upgrade for ease of entry and lack of flushing - it's a little funky to figure out but after a session or two, you get it and the suit does not flush, even in the gnarliest conditions.

I'm 5'8 and 160lbs and wear the Medium Short in the 3/2 and 4/3 but the proto 5/4 suit was a medium and it was fine.

Great for chilly water kiteboarding sessions

Have used it twice for kiteboarding in roughly 55F water and been toasty warm both times. The U-Zip works great, so far the only complaint I have is that it's a bit tight on the neck seal so tried stretching it with a soccer ball for a couple days which seemed to help. I'm 6'1" 180lbs and the Large Tall size fits me pretty well.
