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 fibres to produce a hard-wearing, lightweight garment.  The Weezle is available in 100s of permutations of cut, colour 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 colours 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 fibres 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..

The desire to be warm and dry while under water and a frustration with existing equipment has been the driving force behind the beginning of Weezle Diving Services Ltd ®

Weezle Diving Services is a family business, set up by two divers looking for reliability and value in dive equipment. The innovative & advanced products in our range so far are manufactured to our design to the highest specification by the leading companies in their field.

Our range consists of simple concepts made into quality products, proudly made by hand in the UK.


The Company is small but perfectly formed, consisting of a husband and wife team: Paul and Hilary Child both of who have been diving since Paul bribed Hilary to try the sport in 1990.

They both dive and train all year round and enjoy that that their sport and business are very closely connected, doing much of the extensive product testing themselves.


As most of our diving is done in and around the UK, including training in quarries in the winter, keeping warm was almost as important as keeping safe and in some cases amounts to the same thing.

In February 1998, Paul had the great idea of approaching a local firm who specialise in the use of modern fibres in quality sleeping bags as well as insulated mid layer clothing.

With Paul and Hilary’s design and performance specification and Snugpak’s specialist knowledge of fibres, the first Weezle Undersuit was born. Within the first year the prestigious Design Council Millennium Award was given to the suit and it featured in the display of innovative products for the year 2000. Since then the Company has gone from strength to strength to become one of the Worlds specialist producers of Thermal Underwear for divers.

Raw materials are sourced in the UK, Europe and America and constructed by hand in Yorkshire.
