Product Information

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.
