Compare medium EVA and PU clamshell glasses cases on impact protection, water resistance, weight, and fit. See which hard vs soft glasses case suits your daily carry.
Quick answer
Choose the Medium EVA Case if you need the strongest everyday protection against knocks and light moisture. Choose the Medium PU Case if you want a compact, structured clamshell with a precise fit for medium frames.
Impact protection: EVA foam vs PU shell
The Medium EVA Case uses durable medium-hard EVA foam, which absorbs impacts and flexes slightly under pressure. That makes it the more forgiving option if your bag gets bumped or squeezed. The Medium PU Case uses a PU clamshell construction that holds its shape and keeps frames from being crushed, but the catalog does not specify a foam layer or impact rating, so treat it as a structured cover rather than a shock-absorbing shell.
Water and moisture exposure
EVA shields glasses from minor water exposure, according to the catalog, so it suits damp commutes or a water bottle leaking in your bag. The PU case is not described as water-resistant, so avoid relying on it in wet conditions. Neither case is claimed to be waterproof, so dry wet frames before storing them.
Weight, bulk, and everyday carry
EVA is lightweight and flexible, which makes the Medium EVA Case easier to slip into a small bag without adding noticeable weight. The Medium PU Case measures 6" x 2.2" x 1.4", a compact clamshell that holds its shape but takes up a fixed amount of space. If you carry a tiny crossbody, check that 6-inch length against your bag before ordering.
EVA vs PU: key trade-offs
- Protection vs structure: EVA absorbs knocks and flexes; PU holds a rigid clamshell shape. If your priority is cushioning, pick EVA. If your priority is keeping frames from being bent by bag contents, pick PU.
- Moisture vs ventilation: EVA resists minor water exposure; PU is not described as water-resistant. For damp conditions, EVA is the safer choice. For dry daily commuting, either works. Dry wet frames before storage in either case.
- Weight vs fixed footprint: EVA is lightweight and flexible, so it packs down easily. PU has a fixed 6" x 2.2" x 1.4" footprint, so measure your bag pocket before buying.
