Fit and Sizing
I purchased the large long (size 12-13) Simms G3 Guide Waders. At 6 feet tall with a 35-inch inseam, I found the new version to have a more generous cut than its predecessor. While the length seems similar, the older version had a more tapered fit.

The extra room in the new waders provides better articulation, making it easier to step over obstacles, crouch, and move freely. Initially, I worried about them being too large, but the extra space ultimately enhances functionality.

Pocket Layout and Features
The new G3 waders boast a larger, stretchier chest pocket and a convenient pass-through pocket. I can easily fit a large tackle box in the pass-through pocket, though the zipper stops short of the bottom, preventing items from easily falling out.

A new, sizeable internal pocket adds extra storage space for items like cell phones or battery packs for chest cams. The two belt loops provide options for adjusting the fit and securing the waders around the waist.

Shoulder Straps and Back Design
The upgraded shoulder straps on the newer model feature a waffle-like material for improved airflow and reduced sweat buildup, particularly beneficial in hot weather or while wearing a backpack.

The back of the waders incorporates a more robust yoke system than the plastic found in the older version. A reinforced stitched area on the back offers extra durability and practicality as a net or tool holder.

Boot and Material Differences
Both the old and new versions feature articulated booties for a more natural fit. However, the newer waders benefit from a refined four-layer Gore-Tex construction in high-wear areas for enhanced durability and a three-layer construction in other areas for better breathability and packability.

The new waders' material is designed for improved breathability, less weight, and better packability compared to the older model. Even in hot, humid conditions, they keep the wearer comfortable.

Durability and Gravel Guards
After extensive use (60+ trips), the new waders show no signs of wear, even in demanding conditions. The smooth, seam-free design minimizes abrasion, unlike some other waders.

The new gravel guard is a cuff design that fits securely around the boot without a hook. This significantly reduces the amount of sand and gravel entering the boots compared to the previous hook-and-loop system. The improved design enhances both comfort and durability.

Overall Assessment and Conclusion
The Simms G3 Guide Waders (new version) offer a superior fit, enhanced features like improved pockets and breathable shoulder straps, and notable improvements in the gravel guard design. The improved articulation, larger pockets, and increased breathability make them very comfortable for extended use.

Despite the slightly more generous fit of the new model compared to the older, more athletic cut, the increased comfort and functionality far outweigh this difference. After 60+ uses and enduring many various conditions, the durability and overall performance are excellent. The new Simms G3 Guide Waders are highly recommended and worth the investment for serious anglers.
