I purchased this about 5 years ago at the Lucky Baby Store Jiyugaoka location. The seat of the hip seat is designed to prevent the child from falling, which was very convenient. It is stated that adults can use it with a waist circumference of up to 105cm. I purchased the double shoulder straps as a set, but I didn't use them very often. You attach the double shoulder straps to the hip seat's pouch with a zipper to use them. When not in use, you can store the shoulder straps in the pouch. The thin gray mesh-type hood and the laundry storage bag are unused. Personally, I found the storage in the side mesh part very useful. I hooked my keys with a reel and stored them there, making it convenient to take them out quickly. - Color: Gray - Accessories: Cover, storage pouch, etc. - Instruction manual: Included Although it's not specifically for this, if you'd like, I'll include the light blue drool cover in the image. The lining is denim-style. I handmade it for a different baby carrier, but it also fits these shoulder straps perfectly. I think it will be useful, but it's a used item (it has been washed), so please feel free to let me know if you don't need it. Thank you for looking. Carry style... Upright carry, forward-facing carry
