The Weezle One Piece Undersuit hand made in the UK from the best materials on the market, to the highest specification, using layers of innovative fibers to produce a hard-wearing, lightweight garment. The Weezle is available in 100s of permutations of cut, color and weight to suit your needs for thermal protection and we are happy to advise and assist in your choice.
The Award-Winning one-piece, unisex design incorporates 2 hip pockets and a chest pocket with velcro for security and an elasticated waist for ease. To assist donning, there are innovative ‘slashed’ cuffs which removes the need for thumb loops and also on the leg, elasticated foot loops to keep the legs in place while climbing into your drysuit. On the shoulder is a toughened nylon back panel to protect from rear entry dry zip damage but we can add (for a small cost) personalisation such as a front-loading suit protector strip or a P Valve access. We cannot unfortunately, make to measure as the Weezles are computer designed and cut, but we can custom fit, as we have skilled seamstresses who can make (for a small fee) special alterations to your request, starting with one of our 11 sizes.
The Extreme version is our medium weight of undersuit, shown here in one of the three colors it is available in, blue. Suitable for water similar to those around the UK if worn beneath a tri-laminate drysuit, or for people who really feel the cold and under neoprene.
Constructed from layers of specially chosen fibers each chosen to perform differently each weight from Compact to Extreme plus offering more or less thermal protection as is suitable for under different drysuits, water temperatures and your thermal needs.
Each one piece comes with a good quality double ended zipper and are packed in it's own stuff sack.. Color options Blue & Yellow may need to be made to order, the lead time may vary from 10 days as they need to be produced in batches of 6.
Colors & sizes
The Extreme comes in 3 colors; Black, Blue (check availability) and Yellow (check availability) and Sizes Extra Extra Small to Extra Extra Large, the Long sizes are long in the torso rather than the leg.
We have listed the most frequently asked questions below. If your question is not in the list then please contact us and we will provide you with an answer.
1. Will I need to wear more weight?
No, in fact we get reports back from lots of divers who have actually taken weight off their belts. We would suggest that; as with any new piece of ‘kit’, that you practice in sheltered water first with a thorough weight check before changing your weight belt for a dive in open water.
2. What should I wear underneath it?
Nothing, or as little as you are comfortable wearing. The wicking properties of the suit work best when in direct contact with the skin. Any layers between the skin and The Weezle inner wicking layer need to be of excellent wicking property themselves so as not to hinder the removal of perspiration from the skin. We would recommend (of course) the Weezle Skin, which comes in 2 weights & several sizes, see the Weezle Skin Page; Weezle Skins Swimming gear makes a good base for modesty and it is built to dry fast as well and anything except cotton of course!
3. Which weight of undersuit should I buy?
This depends on the type of diving you do, what type of drysuit you dive in and how much you are effected by the cold. The thermal properties of the Compact & Extreme exceed those of traditional undersuits whereas the Extreme plus breaks the boundaries of undersuit manufacture and is suitable for ice diving. Many of our retailers only stock the Compact as they feel this is all that is required for local conditions. Even though the Extreme & Extreme + are slightly more bulky, they are still more flexible than most undersuits, so movement is not restricted, getting the right suit for your diving is important.
The Weezle Skins can be worn directly beneath an undersuit or in conjunction with one of the Weezle Undersuits, to give a flexible solution. The perfect choice is an Extreme Oxygen set with a set of Extreme Skins; with these you could dive from the Maldives to Antarctica!!
4. While waiting to dive, will I overheat in the one of these undersuits?
No, if you squeeze the air out of your drysuit, effectively vacuum packing yourself, you can alter the thermal properties of the suit to your liking, to a certain extent.
This method of expelling air is one used by many divers immediately prior to diving, to ease their initial descent, always remembering of course to release the dump valve to your required aperture for diving once on the surface.
Because of the excellent wicking properties of Weezle Undersuits, sweat will be moved away from skin towards the exterior of your Weezle. Unlike some other undersuits, the sweat has somewhere to go as it easily is moved to the outer layer, where it is held as an old fashioned typewriter ribbon holds ink, until saturated, about when it is knee deep.
5. Will I be able to get it underneath my membrane/neoprene drysuit?
If you can get a traditional undersuit on under your drysuit, you can get a Weezle suit on. Weezle suits compress down to an unbelievable size and yet expands to fill any gaps resulting in it being the most effective piece thermal protection underclothing on the market.
6. Why isn’t it quilted?
The need to quilt the undersuit has been carefully designed out of the suit. Quilting restricts the free migration of air around the suit hindering it’s removal when dumping is required upon ascent.
Another reason why quilting has been omitted from the suit, is that at every point where there is stitching, a cold spot occurs. By making the filling material self supporting, the need for quilting, and therefore cold spots, is removed. See the Technical Specification for more information.

7. Will the filling move around?
When the filling was designed it was made to be self supporting to remove the need for quilting. We have several suits that have been seriously “used and abused” and none of them have shown any sign of breaking up. We supply the oil industry’s saturation divers with suits for warm water flush systems & these suits also get boil washed. Weezle Undersuits are now the suit of choice as they work well in this situation and last at least 3 x longer than standard undersuits.
8. Is it machine washable?
Yes very! Instructions are given on the sewn into one of the inner seams but here is a more detailed version

9. Will I have to cut holes in it for my cuff/shoulder dump?
No. This above all was a major design requirement of the suit. Air must be able to migrate through and around the suit with minimal restriction. The action of cutting holes in undersuits or replacing sections with netting, reduces the thermal properties of the undersuit. In the case of a cuff dump, removing a section of the undersuit to assist air dumping, occurs at a point where your blood is closest to the surface.
Occasional misinformation has been circulated about problems caused by blocked valves, usually by those who haven’t worn a Weezle or are trying to sell you something else. Any slow venting is usually caused by inexperience and over-weighting or a faulty valve rather than the Undersuit; which itself is breathable.
Weezle undersuits are made by the layering of three special materials, each with its own qualities. These three materials perform together in a unique manner which no suit containing a single factor can match.

Lightweight, highly windproof, water repellent fabrics, exceptionally breathable and able to wick moisture away from the source, ideal for sleeping bag linings and mid-layer insulated clothing.
Windproof to the industry standard of 3 cubic feet per minute.
DWR – Durable Water Repellent, a British Standard Spray Rating of 4 Minimum
Breathability rating of 12l/m²/24h
Exceptionally breathable and able to wick moisture away from the source
and spread it over a large surface area, from which it can quickly evaporate.
As part of our continuing development process to keep our synthetic insulation at the leading edge we are pleased to introduce the next generation in thermal technology Softie® The filling is in fact a combination of fibers with different crimp-systems and surface finishes. Its feel is remarkably close to down, and it’s very much easier to care for! It contributes to an almost luxurious softness, with excellent drape, while its loft gives it an a truly outstanding thermal performance.
It’s unique combination of fibers actually swells to trap more air when they start to get warm. A surface treatment applied to the outermost layer of fiber, whilst helping to keep the fiber stable and stop migration, also has a degree of inherent water repellency. This extreme fiber was chosen for its resilience and durability in the field and is made only for ourselves and Snugpak in Switzerland.

Finally, the lining fabric has a plaited weave in which different yarns are placed on the two faces of the fabric. Microfibre yarns (less than 1 decitex in thickness) go on the outside, while macro-filament yarns (3 decitex) are placed on the inside and are raised to create a short pile.
The pile side has a feel which is very similar to suede – soft and comfortable, warm to the touch – and it traps air and body heat in its fibers.
Its other basic ability is to wick moisture from inside to out. It exploits a basic property of physics – that water will always move from a low to high surface area – i.e. from macro filament inside to micro filament outside.
