Flexon H6001 vs. Similar Rectangle Frames
The Flexon H6001 sits in the mid-range of Flexon's rectangle eyeglass collection, balancing price, features, and style. Here's how it compares to other popular models in our catalog.
H6001 vs. Flexon 603: Budget-Friendly Alternative
The Flexon 603 ($102.15) offers the same core memory metal technology as the H6001 but at a lower price. Both are full-rim rectangle frames built for durability, but the 603 comes in smaller lens sizes (49mm and 51mm) compared to the H6001's 55mm and 57mm options. If you have a smaller face or want to save $14, the 603 is a solid choice. The H6001 offers more contemporary styling and better fits for medium to large faces.
H6001 vs. Flexon NATHANIEL 600: Style Variation
At the same $116.31 price point, the Flexon NATHANIEL 600 offers a slightly more geometric take on the rectangle shape. Both feature titanium-nickel alloy construction and memory metal technology. The NATHANIEL 600 is available in a 54mm lens width with a 17mm bridge, making it ideal for medium faces. Choose the H6001 if you prefer classic rectangle styling or need the larger 57mm size; go with the NATHANIEL 600 for a more modern geometric look.
H6001 vs. Flexon E1042: Premium Upgrade
The Flexon E1042 ($140-$148) represents Flexon's premium tier. While it costs $24-32 more than the H6001, it offers enhanced construction and materials. Both are full-rim rectangle frames with memory metal, but the E1042 is built for customers who want the absolute best in durability and refinement. For most wearers, the H6001 provides all the performance you need at a better value.
Our recommendation: The H6001 hits the sweet spot for most buyers—proven memory metal technology, versatile rectangle styling, and two size options at a fair price. Choose the 603 if budget is your priority, the NATHANIEL 600 for a geometric style variation, or the E1042 if you want Flexon's premium features.
