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

Source: Bare’s size chart (original chart). Values in the second unit come from Bare’s own chart where it prints them.

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.

Excellent wetsuit but will it crush quickly like other wetsuits?

I purchased a BARE 5mm Reactive wetsuit (open box), which was like new, to replace my 1.5 yr old BARE 5mm Velocity wetsuit which had collapsed to only 2.5mm after 3 diving trips (~100 dives). The Reactive wetsuit is well constructed and very flexible. I had to increase the size of the Reactive suit, as it was smaller than the BARE Velocity suit of the same size. Tremendous customer service by Dive Catalog to exchange the wetsuit for proper size. I hope the Reactive suit does not crush so quickly like my other wetsuits (BARE, Henderson, Pinnacle). Hoping that the new technology in this suit will keep me warm below the thermocline.

Perfectly Built

Best of the many many diver hangers in my life. Easily supports my steel-plated BCD, while still donned with all of my accessories. No cracks, bends, or dents. Has even supported my BCD w/ a steel 100 tank attached (not recommended, for safety purposes, though).

Will continue to use this hanger for the long-term. No brainer.

Go-to Dive Hanger

This is a must-have for every diver. It's the quintessential hanger for all dive gear in one small package.

DiveCatalog's "Quick Dry Multi Accessory Dive Gear Hanger for Boots, Gloves, Hood" is set at a great price for a great product. Versatile enough that I've purchased extra hangers to organize my BMX racing gear.

Must-have for divers and anyone looking to organize their adventurous outdoor activities equipment.

Solid Hanger w/ Tons of Options

Does it's job and then some. The added accessory arms gives you options for a multitude of storage solutions. Solid build, solid pricing, must have for owns of dive gear.

New to this hanger...Now I'm a believer

Used tons of dive hangers, but never an upside down hanger. Game-changer for me. Will now add more of these in the near-future.

With it's swivel head design, it can cram itself into my tight dive locker, while still donning a ton of gear.

DiveCatalog's "Upside Down Drysuit Hanger w/ Regulator and Accessory Hooks" is a great product with solid construction at an affordable price. All of that with Dive Catalog's customer support/satisfaction guarantee.
