How Bare measures
Wear minimal clothing (ie. T-Shirt, shorts, bathing suit) at the time of measuring. All measurements must be taken with a soft tape measure pulled snug but not tight. Stand straight, looking forward with your feet flat on the floor. It is best to have help taking the measurements, in order to remain in the optimal measuring stance.
- Weight: As close as you can accurately
- Height: From the top of your head to the floor
- Chest: Measure around the fullest part
- Waist: Measure around the narrowest part
- Hip: Measure around the fullest part
- Torso: Top of shoulder to crotch vertically
- Inseam: Measure from crotch to floor

Product Information
The BARE SB Mid Layer Full is a one-piece men's fleece undergarment built to wear under a drysuit as the mid layer of BARE's SB System, cut from a stretch, breathable, compression-resistant polyester/spandex anti-microbial fleece with Polartec Power Stretch technology, and available in black.
Who it is for
This mid layer suits drysuit divers who want warmth without the bulk of a traditional fleece undergarment, including divers who move across changing depths and need the insulating value of the fabric to hold up under compression. It works as part of the full BARE SB System or on its own as a stand-alone undergarment for divers who prefer a single piece of thermal protection.
Key details
- Fabric: polyester/spandex anti-microbial fleece with Polartec Power Stretch technology, high 4-way stretch, PFC-free
- Front entry zipper offset at the neck to reduce bulk under the neck seal, with an extra-long diagonal front zipper that allows 2-way insertion of a pee valve relief tube
- Zippered stretch pocket laminated to the left waist for a key or ID
- Low profile thumb loops to assist donning and lycra stirrups to keep the pant legs in place when donning the drysuit
- Flatseam stitching throughout and a one-piece construction for comfort
- Moisture management and quick-drying properties plus anti-microbial treatment for odor control
Compatibility and sizing
The SB Mid Layer Full is designed to pair with the rest of the BARE SB System or to be worn as a stand-alone garment. It is offered in Men's sizes S, M, MS, MT, ML, MLS, MLT, L, LS, LT, XLT, XL, XLS, 2XL, 2XLS, 3XL, 3XLS, 4XL and 4XLS, color black.

- Low profile thumb loops: Assist with donning the garment.
- Zippered waist pocket: Stretch pocket laminated to the left waist stores a key or ID.
