About Waterproof Warmtec HD 300g (10.6 oz) Fiberfill Undergarment

Waterproof's New Warm Tec Fiberfill Undergarments are made from 10.6 oz (300 g) Soft Polyester Fiber with Scald Surface. The outer shell is a 100% Nylon Taffeta 210T Polyurethane silver coated with a weight of 2.5 oz (70 g). The form fitting legs, waist and vented shoulders provide rapid response air exchange to accommodate the most demanding dry suit dives. Waterproof's compressible fiberfill material also minimizes the space required for transport making this undergarment/surface wear an all around top performer for discriminating divers.

This undergarment is designed for water temperatures below 50 degrees Fahrenheit (10 C). Garments outer shell is durable water and wind resistant. Zippered snug fit" legs prevent air shifts and the elastic waist creates a tight form fit. When you're too warm there are ventilation zippers in the arm pits.

Yes but not with 7mm


from Phoenix, AZ, US

The outfit would be a great addition if you were to wear a Tri Lam drysuit. It is stylish, warm and fit great. I am using a Bare D6 Pro 7mm drysuit and the Waterproof Warmtec HD 300g was just too fluffy to wear underneath. It compressed nicely but when ascending would expand adding just too much buoyancy. I liked it but not for my application.


Very warm, excellent construction


from Auburn, WA, US

I dived a Weezle Compact for years and generally liked it. When I got my Waterproof suit last year, I decided to try their undergarment and selected the 300g version for diving in colder Pacific NW waters. Unlike the Weezle, which is like wearing a sleeping bag, the Warmtec feels thicker, more durable, and fitted. It has four zippered pockets. It also has a high neck piece that I thought would get in the way of the seal, but works just fine. I did have to add weight with this undersuit because it doesn't compress as much as the Weezle. Overall, I'm very impressed with the Warmtec and would absolutely buy it again. In fact, I'm considering getting the 200g version for the summer months.


It's a good buy
