Ultrawarmth Base Layers provide more endurance, faster recovery and increase thermal energy with Ultrawarmth Celliant® Infrared fabrictechnology determined by the FDA as a heat recovery medical device to. Ultrawarmth Base Layers seal in warmth and create a protective heat barrier. Advanced stretch-breathable fabric draws moisture away from the body to create a dry zone, while moisture is dispersed over a larger surface for quick evaporation. Ultrawarmth Base Layers are essential to a diver's drysuit system, and can include a mid-layer for additional warmth, keeping divers warmer and more comfortable for longer.


Ultrawarmth Base Layers increase thermal energy, provide more endurance and faster recovery thanks Ultrawarmth Celliant Infrared® Technology embedded in the fabric of the material. Base Layers are available in men’s and women’s top and pant, making them essential to a diver's drysuit system and ensuring ultimate warmth in all cold conditions.


Designed to provide more warmth with less bulk, the Base Layer pattern is a form fitting design. It improves comfort under all BARE drysuits by eliminating the bulk that often comes with excess material. Our 3D patterning results in the perfect fit for both men and women.


Advanced-stretch breathable fabric draws moisture away from your body and creates a dry zone, next-to-skin barrier. Moisture is dispersed over a larger surface for quick evaporation. 230-g Celliant® Infrared stretch fleece fabric has a smooth face for easy layering, and a fleece-brushed back for superior warmth and moisture-wicking performance with Microban odor control.


The versatility of Ultrawarmth Base Layers allows you to mix and match the top and pant with any drysuit system for men and women. Base Layers are the only drysuit undergarment in the industry with scientifically-validated and FDA-determined Ultrawarmth Celliant® Technology, all while maintaining BARE’s exceptional standards of Fit, Craftsmanship and Innovation.

Warmth and comfort are important. So when it comes to thermal protection, our selection of drysuits, accessories and modular layers enables divers to create their own personalized thermal protection system. By assembling these components, you can establish your own personal comfort level based on water temperature and dive duration.



Trilaminate drysuits require Constant Volume Exposure (CVE) protection, which means air volume and the “loft” of the undergarments provide nearly all the insulation. Conversely, neoprene suits provide significant insulation although the suit alone provides Variable Volume Exposure (VVE) protection. Both compression, undergarments and air volume in the suit impact the neoprene suit’s thermal properties.

Both types of drysuits require you to complete your drysuit system in order to keep you warm and protected. We developed our drysuit accessories with as much care as the drysuit itself. Innovations such as bulk-reducing, modular layers, and hoods with Sealtek liquid seam tape, keep you diving longer.


Drysuit outer layers provide either CVE or VVE protection, depending on whether it is made from trilaminate or neoprene material. Both require the addition of under layers to keep you warm, the decision becomes how many and how thick. Many divers will use existing layers that weren’t designed for dive. While this may be a tempting option, BARE layers are modular and designed specifically for diving to ensure the highest level of comfort and performance in every dive situation. Patterns for the SB System have been thoughtfully developed to ensure that when layering, excessive bulk from stacking panels and zippers is limited to maximize comfort and performance in every diving environment. We have gone to great lengths to source and develop the highest performing fabrics to ensure the best moisture management and warmth.


Your base layer is the first stage in moisture and thermal management. This is the most important layer in keeping a diver dry and comfortable. The SB System Base Layer is made from an advanced stretch, breathable fabric that draws moisture away from the body creating a dry zone next-to-skin barrier.


The mid layer is the warm fleece layer. This fabric was designed for military use and when we created it with our partners at Polartec®, we knew this was the perfect application for dive. This is a one-of-a-kind compression resistant, double layer fleece. Don’t be surprised by the lack of bulk. In this case, more bulk definitely does not mean more warmth.


When the needle drops, we reach for our super plush and super warm Polarwear. And, if you tend to get cold quickly, this is the drysuit underwear for you. Polarwear underwear offers a double layer of Hi-Loft Thinsulate™ in the torso for extreme coldwater diving. Combine it with the SB System Base Layers for a customizable warmth that doesn’t sacrifice mobility.
