Matt Says:

"Definitely one of the best cold water Women's wetsuits out there, the D-Lux Mod is truly two suits in one. If you're getting into warmer water and the air temp is mild then wear it with the regular neck, then when the water gets cold and the winds start blowing throw on the zip in hood and you are water tight and warm! The Ultraflex DS neoprene is super stretchy so even for a 5mm suit you'll be unrestricted out in the water and the fully taped seams make this suit one that will definitely hold up much longer than a traditional GBS suit."


The O'Neill Women's D-Lux Mod Wetsuit is a high performance feminine minded wetsuit with great features. The D-Lux Mod is a unique convertible wetsuit that allows for a hood to interchange with a neck piece, making it versatile for surfing in all kinds of cold water conditions. Built with 100% UltraFlex Stretch Neoprene and insulating UltraFlex Firewall panels, the D'Lux Mod has a focus on warmth, the feminine shape for a snug fit and maximum comfort in the water.

Single Fluid Seam Welds, Plasma Seals and a Single Super Seal Neck round this suit out nicely ensuring to minimize flushing and leaks, keeping water out so you stay warm. With options for anything from snowy winter afternoons to summer in the PNW, the D'Lux will be in your surf arsenal year-round. Delivering a clean look and impressive features to match, the D'Lux is a perfect option for fun no mater what Mother Nature has to offer.

O'Neill Women's D-Lux Mod 5/4 Wetsuit - 2015 Overall a Great WetsuitReview by Vee_311 Vee_311
1. Very lightweight, flexible and comfortable. This 5/4 actually feels lighter and more flexible than my Xcel 4/3. Also, it is easier to paddle in compared to my thicker 4/3.

2. As for warmth, I was very comfortable for at least an hour in sea temperature in the low 40’s. It may have lasted longer, but my hands and feet were getting cold (booties/gloves selection for the sea temp were the limiting factor there). But, the wetsuit itself kept the rest of my body warm.

1. A bit of a "work-out" to remove this gear...I found it was a little more challenging to take this wetsuit off after surfing, but it seemed worth it for the awesome “gummy-like” flexibility it provided.

2. The modular attachment for the neckpiece (the one w/o the hood) seems a little flimsy and more challenging to zip the front section compared to my other front entry wetsuits. I think it’s probably a little more challenging if you are on the "bustier" side, since it becomes difficult to keep the zipper cinched while securing it all the way. The neoprene in the neckpiece actually tore after a few times of use. BUT, Cleanline was really great about quickly getting a replacement from O’Neil ASAP without any trouble.

Even with the minor issues, it is still a great wetsuit…I loved surfing in it every time. Also, Cleanline was AWESOME about helping me pick out the right wetsuit between the options I was considering, as well as recommending the best size (which is a little more challenging for us petite surfers since the “short” option does not come in all wetsuit designs). Cleanline definitely steered me in the right direction and I have been very pleased with this purchase overall. Mahalo.

O'Neill Women's D-Lux Mod 5/4 Wetsuit - 2015 tight squeezeReview by chickook chickook
This suit is very warm, so warm that when surfing in 48 degree water with 40-something degree air, I had to pull the neck back and flush in some ocean water to cool myself off. I went up one size when I ordered this based on reviews I read, but I wonder now if I should have gone up two. So far it seems impossible to get into and out of without help.

O'Neill Women's D-Lux Mod 5/4 Wetsuit - 2015 VERY smallReview by Jeff Jeff
My wife was really excited when I bought her this suit--we were warned we should size up because they fit small. I think you should size WAY up. We returned it for a different style. One with a zipper so she wouldn't need help getting in and out of it! Otherwise, it looks like an awesome suit.

O'Neill Women's D-Lux Mod 5/4 Wetsuit - 2015 To hood or no hood, that is the questionsReview by Shenaynay Shenaynay
I love the versatility of this suit! So far this year I have not needed a hood (surfing the Oregon coast), and knowing I have the option makes it seem like I have two suits in one! Plus this suit dries overnight so I'm always nice and warm when I jump back into the water. I'm super happy with this suit.

O'Neill Women's D-Lux Mod 5/4 Wetsuit - 2015 size upReview by Pinky Pinky
I have this wetsuit and many O'Neill wetsuits. I wear a 6 usually but find in the O'Neill winter suits I have to size up. So I get an 8 in this one. When I was having a problem doing up the zipper (it is complicated) the O'Neill guy who designed the suit called me and walked me through how to do it. He even has a video if you need it. The suit is great, I use it for mid season surfing on Cape Cod and it keeps me warm sometimes through December.

O'Neill Women's D-Lux Mod 5/4 Wetsuit - 2015 I returned itReview by Mary Mary
O'Neill has a reputation for stretchy wetsuits. However I had a very difficult time just getting my shoulders and arms in the suit. And I mean difficult! It took forever to get it on so I returned it. I take a size 4, this suit was a size 4. The cap was again almost impossible to get over my head. The struggle wasn't worth it.
