Size Chart


The Colby + Yamamoto 3/2mm  Chest Zip Fullsuit is designed for cool to mildly warm conditions, typically used in water temps in the high 50s to mid 60s.  

Like all Colby + wetsuits, it features Yamamoto #39 in the torso for durability, shape retention and warmth, and Yamamoto #40 in the shoulders and arms for added flexibility and freedom to reduce paddling fatigue.  We use a custom-made jersey from the world's premiere jersey provider which has a silky hand feel with amazing stretch and resilience.

The Colby + Yamamoto 3/2mm Chest Zip Fullsuit features triple-glued and blindstitched (GBS) seams with internal taping in critical areas (those that take the most abuse).  GBS stitching combined with internal tape will improve the longevity of the suit and also helps reduce leakage from sew-through.  It doesn't completely alleviate it, but certainly helps. 

To help alleviate leakage, and importantly, we've applied a rubberized liquid seal treatment to the exterior seams, which ends just below the armpits.  This will dramatically reduce leakage in the lower body, crotch and torso.  And because we've left it off of the arms and shoulders, you'll have unmatched freedom and flexibility in the upper body.  

The chest zip design is a tried-and-true standard and features an all-metal YKK zipper pull which will outlast the life of the neoprene.  It's tough as nails, but not too bulky or heavy.  

The dark grey upper body jersey turns nearly black when wet and also indicates where the Yamamoto #40 is used.


Yamamoto Neoprene Soft and flexible feel. Fantastic warmth and lightweight as well. More expensive per yard and if not taken care of, will degrade like other neoprene (no faster, but not impervious to mishandling)
Jersey Our proprietary jersey lining is the most comfortable and flexible we've ever felt (and surfed in) Not as bullet proof as cheaper jerseys
Liquid sealed seams Reduces the inflow of water through seams and pinholes from sewing needles Reduces flexibility and can delaminate if left in the sun to bake
Extra durable knee pads Won’t delaminate or fail as easily for guys that drag a knee when popping up or push under waves using their knee on the tail Slightly less flexible
Watertight zip Reduces leakage through zipper teeth Water will still get in the wetsuit (slowly), but this is how it’s meant to work. The other tradeoff is it’s a bit more expensive than the non-water-tight zips
Triple glued + blindstitched construction No buildup around seams to give you a rash. More mobility in your upper body More expensive and hand-constructed, so if there’s human error (missing a spot of glue for example), it can sometimes be felt in the form of water seepage/leaking or even failed seams (warranty will cover for 1 year)
Internal neoprene taped seams Adds strength to the seams and helps prevent additional water seepage/leaking More expensive to produce. Can limit flexibility (though not as much as liquid seal treatment), and sometimes will delaminate if not taken care of (left in the sun) or wasn’t properly glued at the factory (warranty will cover)

Best wetsuit ever!!

I've been surfing for 40 years, and this is the best wetsuit I have ever worn. Feels super thin and flexible, but my 3/2 is as warm as a 4/2. The material is just so soft and buttery, an absolute steal at this price.

Mike Tedesco

Hands-down, Best suit for your buck. comfortable and warm what more do you need?

Quality all around

Wetsuit quality feels top notch. So soft and buttery. Customer service was even better quality! I had some sizing issues and James was extremely kind/helpful over the phone. Figured out the wrong size was sent to me and the correct one was sent out right after we spoke. Only complaint is the groin area - not a ton of room so it's a bit tight, but it sounds like the new batches coming up will fix that issue. Regardless, stoked to try it out!

Matty Passa
Amazing quality

Never leaked water and the flexibility/warmth with the fluid seems impressive.

Really like the chest zip from right to left. The extra panels inside the neck area roll on perfect & don’t get in way. Chest pull over area is 10/10 in terms of insulation & comfort!!

Noticed the suit drys really fast and the neoprene doesn’t absorb much water, keeping the suit lighter.

The wetsuit feels like a premium product at an affordable price!
