BARE Polar Stretch Mid-Layer Boot Liner
By BARE Sports | Polartec® Power Stretch® Technology | Premium Drysuit Thermal Sock
Keep your extremities warm and prevent cold-toe discomfort on long dives with the BARE Polar Stretch Mid-Layer Boot Liner. Crafted from advanced Polartec® Power Stretch® fleece, these high-performance thermal socks offer 4-way stretch flexibility and compression-resistant loft. Exceptional warmth when used on their own or under boots, our socks are designed to keep your feet toasty in the coldest conditions. Designed to wear inside soft neoprene drysuit socks, rock boots, or wetsuit booties, they maintain insulating warmth under suit pressure while actively wicking perspiration away from your skin.
Key Features & Foot Insulation Benefits
- Polartec® Power Stretch® Fleece: Dual-surface 4-way stretch fabric features a pill-resistant smooth outer layer for easy suit entry and a soft brushed interior that traps heat.
- Compression-Resistant Thermal Loft: Retains its air-trapping insulation even under pressure from tight drysuit socks and fin foot pockets.
- Advanced Moisture Management: Rapidly draws perspiration away from the skin to the outer fabric layer to prevent clammy feet and chilling during surface intervals.
- Chafe-Free Flatseam Stitching: Low-profile flatlock seams eliminate pressure points, hot spots, and bunching under rigid rock boots or fin pockets.
- Anti-Microbial & Quick-Drying: Inhibits odor-causing bacteria growth and dries rapidly between repetitive dive days.
- Versatile Layering: Can be worn on their own or layered underneath heavy thermal socks and rock boots for extreme cold-water diving.
