Product Information
The Hollis AUG 450 Top is a men's drysuit base-layer garment made from dual-layered, high-density stretch technical fleece weighing 450 grams, built to wick moisture away from the skin while adding warmth without bulk under any type of drysuit. It is fully machine washable and sold in sizes S through 3XL as a standalone top, with a matching bottom sold separately for mix-and-match sizing.
Who it is for
This undergarment suits divers who wear a drysuit in cold or temperate water and need a moisture-managing base layer. It can be worn alone or layered with other Hollis AUG undergarments for extreme cold-water diving.
Key details
- Dual-layered, high-density stretch technical fleece weighing 450 grams
- Insulates without adding bulk inside the drysuit
- Zippered arm pocket for small items
- Thumb loops for secure, easy donning and layering
- Fully machine washable without degrading its wicking performance
- Compatible with all types of drysuits and can be combined with other AUG undergarments
Compatibility and sizing
The men's top is offered in S, M, L, XL, 2XL, and 3XL. It is sold separately from the AUG 450 bottom, so divers can choose a different size for top and bottom if needed, and a dedicated women's version is available as a separate product for divers who prefer women's sizing.
