Stay comfortable and protected in cold-water conditions with the Seac Drysuit Unifleece Insulating Undergarment. Designed to be worn beneath a drysuit, this lightweight thermal base layer provides reliable insulation while maintaining excellent breathability, helping divers stay warm throughout long dives in challenging environments.

Constructed with a soft, two-layer fleece fabric, the Unifleece combines superior warmth with all-day comfort. The water-repellent outer surface helps reduce moisture absorption, keeping the garment lighter and drier before and after your dive. Its ergonomic fit allows unrestricted movement, making it ideal for recreational, technical, and professional scuba diving.

A convenient double-ended front zipper makes dressing and undressing quick and easy, while integrated ankle stirrups keep the legs securely in place when putting on a drysuit, preventing the fabric from riding up. Two zippered pockets provide secure storage for small essentials and dive accessories, adding extra functionality without compromising comfort.

Whether you're exploring cold lakes, deep wrecks, or winter dive sites, the Seac Unifleece Drysuit Undergarment delivers dependable thermal performance and freedom of movement for every cold-water adventure.

Great fleece garment for moderate temps

I bought this undergarment for a recent Red Sea trip with water temps in the 68-72F range. It was comfortably warm for recreational dives <90 mins, but I also tolerate cold well. If you get cold easily you might want to layer with a warm base layer or go up to a 200 weight garment. I am 6'1", ~205 lbs and purchased an XL. It was a little snug. The only reason I dropped 1 star was because the fabric has started to pill up. I definitely like the 2 way zipper because it makes it much easier to use the restroom.

Warm water drysuit use

I bought this for warm water drysuit diving 50 - 72 degree water temps. It's not very thick seems like it's going to be comfortable to dive. This thing is perfect for summer diving In a dry suit in New England. Watch the size they run small.

One More Size for Men

It's thin and help to use as 2nd layer over clothes. I tested and I'm going to need to put more clothes next time due I did with tank top and shorts. This product fit me well though I use small size as man but this is unisex size, so I choose Medium and fit me well.

I returned due to sizing but the garment was quality

I can't complain about the quality of the garment, but size chart isn't accurate. I am 6'2" on the nose, and the XL was listed as fitting me. It didnt, it was too short, fitting someone 6' comfortably imo.

Great base layer

This is a base layer, as in not a lot of warmth given. It is great for movement and shedding perspiration. I am the most comfortable at 68F to 76F water in a trilaminate dry suit. For what this is, it is great.

Fits nice, zipper opens from top and bottom

When I first opened the package I saw the outside of the garment and didn't see fleece so thought it was a cheap item, then while unzipping it to try on, I saw all the fleece was on the inside and I was very please. I wore this under my drysuit while sailing in 65 degree water on a chilly day and it really helped keep me warm. The only negative was one foot stirrup slipped over my ankle while I was putting the drysuit on. The garment never rose up and stayed tight to my ankle and calf. Works great and glad I purchased.
