{"type":"firestarter.listing","listing":{"id":"lst_S3XJMgJ9","product_name":"Essential Boyshort","category":"Underwear","description":"50% brief, 50% short, 100% incredible. Our Essential Boyshort brings boxier coverage than the Hipster, making it your go-to for lounging, lunging, layering, or taking a spontaneous swim. Under a dress or your ski bibs, it shape-shifts as effortlessly as you do.\nOur seamless Merino wool and elastic-free waistband mean no digging, no rolling, no adjusting—ever.  Finished hem leg openings move with you from early-morning miles to end-of-day exhale. So buttery-soft, you’ll forget you’re wearing it... until you realize you never want to take it off.\nNote on coverage:  The beauty of our bodies is that no two booties are the same (that's the magic). Coverage will naturally vary depending on your shape and how high you wear them on the hips.\nBonus: Our proprietary GLDNspun™ technology is crafted with ZQ+™, RWS, and Woolmark-certified Merino, and OEKO-TEX® 100-certified fibers–that means it is sustainable—free from BPA, PFAs, and other toxic “forever chemicals.”\nDouble Bonus: Our Boyshorts can be worn two ways: snug around the hips or pulled up just below the belly button for a higher-waisted fit and more tummy coverage.","images":["https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-8258830_f6983bb9-6f9b-417e-bec3-1cd450b95328.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-6300578_5eba3c34-d3c5-4dc6-8f08-3319f116c72d.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-2940735_fd28fd40-a768-4620-ae42-1bcd511885f1.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-8519314_8012ebe7-455e-44d8-9242-51ce006cda59.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-4254412_b169cad3-ae8d-4679-b9fc-88aa54e22d2d.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-1799424_a835b6ef-f83d-4507-9235-e17b7b42340a.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-6008166_90f2ecd3-b71f-4445-8e58-f8af83c0c06b.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-9663824_9cde9a4c-ef78-4905-b61b-483992bf48c9.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-3059426_3eb3d8ff-1fba-4ce9-9a29-270ef53f56c8.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-1232898_d2ac0000-827e-44ab-898c-c15a2dfedf9e.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-6569759_39c5c345-b72e-4137-b9ed-65b133a8db43.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-4267331_feb95161-6e6a-47ea-8af6-cbf481594e1a.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-1723314_be52a74a-335e-4d16-8cd9-b51c0e7eeea4.jpg?v=1776938958","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-5173342_ccf9eb5a-7ee5-4879-b32c-e95f4dbaa7c6.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-2127239_2a7c5303-6b22-478b-99fc-ab6d9d26fedc.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-3031805_c3fefc64-dc75-41fa-996e-9439c4bdcb91.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-8291531_073c646b-9cf0-47c2-af48-3fe7b2eefb1c.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/essential-boyshort-9378173_9720c1f5-e37a-4b8d-850d-ecb5c60e9f07.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Boyshorts_Front_View_Transformative_Teal_Seamless_Merino-19_76688ffb-29d8-43ed-8315-3bbe14f3b90d.jpg?v=1776938958","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Boyshort_Side_View_Transformative_Teal_Seamless_Merino-Wool24_4be50739-5467-4de5-8a0a-d04f60652b5a.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Bralette_and_Hipster_Transformative_Teal_Seamless_Merino-35_3b331361-3c3c-4b0b-a9cb-11fdf9a53760.jpg?v=1776938957","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Seamless_Merino_Wool_Boyshort_Underwear_Future_Dusk_2.jpg?v=1780335841","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Seamless_Merino_Wool_Boyshort_Underwear_Future_Dusk_3.jpg?v=1780335891","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Seamless_Merino_Wool_Boyshort_Underwear_Future_Dusk_5.jpg?v=1780335804","https://cdn.shopify.com/s/files/1/0071/9372/2964/files/BRANWYN_Seamless_Merino_Wool_Boyshort_Underwear_Future_Dusk_4.jpg?v=1780335992"],"price":35.7,"currency":"USD","in_stock":true,"inventory_qty":369963,"dynamic_pricing":false,"listed_at":"2026-06-18T20:43:01.477Z"},"share_url":"https://firestarter.network/l/lst_S3XJMgJ9","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
