Bare Ultrawarmth Mens Base Pant Layer Drysuit Undergarment

Q: Is this base layer pant warm enough on its own under a drysuit?

It is a base layer, so it is designed to sit next to the skin as the first layer in a drysuit system. The 230-g OMNIRED Infrared stretch fleece has a high warmth-to-weight ratio and a fleece-brushed back for warmth, and BARE builds the Ultrawarmth line to mix and match with any BARE drysuit system.

Q: What are the ankle stirrups for?

The ankle stirrups keep the pant legs from riding up while you pull on a drysuit and while you dive. The ankle stirrups keep the pant legs in position under a drysuit so the fleece does not ride up while you dress or dive.

Q: What sizes and colors are available?

This men's pant is offered in black in sizes S (Small), M (Medium), ML (Medium Large), L (Large), XL (X-Large), 2XL (2X-Large) and 3XL (3X-Large). The fabric is a stretch fleece with a form-fitting 3D pattern, which keeps bulk down under a drysuit. If you are between sizes, contact us at 888-701-4017 and we will help you choose.

Q: Does this pant come with a matching top?

No, the pant is sold on its own as a single garment. BARE also makes a matching Ultrawarmth Base Layer Top, and the two are designed to be worn together as a base layer set.

How Bare measures

Your suit may fit perfectly but sometimes little things can affect a diver's experience. A hood that bunches or lets water in is just enough discomfort to change the focus of a dive. Our hoods are designed with anatomical fit so it is important to measure for the perfect fit.

Forehead: Start in the center, front and measure around the widest part.
Neck: Start in the center, front and measure around the middle of the neck.

Product Information

The BARE Ultrawarmth Men's Base Layer Pant is a drysuit undergarment base layer built from 230-g OMNIRED Infrared stretch fleece, with a smooth outer face for easy layering, a fleece-brushed back for warmth and moisture wicking, and ankle stirrups that keep the legs in place as you pull on a drysuit. It is offered in black in sizes S through 3XL.

Who it is for

This pant is for male drysuit divers who want a next-to-skin layer that adds warmth without bulk. Because the fabric is quick drying back on the surface and when the suit is vented or removed, it suits repetitive dive days, boat diving and cold-water training where you spend time out of the water between dives. BARE designs the Ultrawarmth line to mix and match with any BARE drysuit system, and the pant pairs with the matching Ultrawarmth Base Layer Top for a full base layer set.

Key details

Fabric: 230-g OMNIRED Infrared stretch fleece, which BARE describes as converting body heat into infrared energy to increase thermal energy, improve circulation and aid faster recovery.
Construction: flatlock seams to minimize chafing, plus a form-fitting 3D pattern that reduces bulk under a drysuit.
Comfort: brushed elastic waistband next to the skin and ankle stirrups for positioning.
Care performance: moisture-wicking, quick-drying fleece with antimicrobial (Microban) odor control.
Sizing and color: black, sizes S, M, ML, L, XL, 2XL and 3XL; manufacturer style number 018141.

Frequently Asked Questions

Is this base layer pant warm enough on its own under a drysuit?

It is a base layer, so it is designed to sit next to the skin as the first layer in a drysuit system. The 230-g OMNIRED Infrared stretch fleece has a high warmth-to-weight ratio and a fleece-brushed back for warmth, and BARE builds the Ultrawarmth line to mix and match with any BARE drysuit system.

What are the ankle stirrups for?

The ankle stirrups keep the pant legs from riding up while you pull on a drysuit and while you dive. The ankle stirrups keep the pant legs in position under a drysuit so the fleece does not ride up while you dress or dive.

What sizes and colors are available?

This men's pant is offered in black in sizes S (Small), M (Medium), ML (Medium Large), L (Large), XL (X-Large), 2XL (2X-Large) and 3XL (3X-Large). The fabric is a stretch fleece with a form-fitting 3D pattern, which keeps bulk down under a drysuit. If you are between sizes, contact us at 888-701-4017 and we will help you choose.

Does this pant come with a matching top?

No, the pant is sold on its own as a single garment. BARE also makes a matching Ultrawarmth Base Layer Top, and the two are designed to be worn together as a base layer set.
