This is an "Excellent Weave" item from "ENTRY SG." I've used it about 8 times, including for travel. The color is navy, a classic color that goes with anything. This is a timeless classic, exquisitely arranged with "ENTRY SG's" interpretation. It's packed with details that appeal to men, yet the appearance is extremely simple. From details like the binder neck, to its pattern, material, comfort, beauty, sewing, and durability, it's a professional-grade finish in every aspect. The material, woven slowly like hand-knitting on a rare Wakayama loopwheel knitting machine, is a seamless tube that feels comfortable, and the silhouette is beautiful. The basic and simple design, created from the finest materials, is not affected by trends and will continue to be worn for years to come. Here are the key points and details: ◼️ Binder Neck This is a binder specification that sandwiches the body fabric. The 25mm wide ribbing is sewn with a two-needle stitch. The two-needle stitch uses slightly thicker #30 thread, making the collar less likely to stretch. ◼️ Woolly Thread Hemming The hem and cuffs are finished simply with hemming. In addition, by using high-stretch woolly thread, the sewing is beautiful and suitable for the hem, which is the most stressed area during wear and removal. ◼️ Silhouette The material is flexible and stretchy, and the body and armholes are designed to fit the body. This eliminates bulkiness and reduces interference with outerwear when worn as an inner layer. It's an exquisite silhouette that also works well as an inner layer. I would like to pass this on to someone who will cherish it.
