# Track-Inspired Summer Set NEEDLES x STUDIOUS Reworks Poly Smooth Classics into Warm-Weather By Amy Duong | Published 2026-06-05 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/poly-smooth2 References: [studious.co.jp](https://studious.co.jp/shop/Needles/r/rnds/)  [NEEDLES](https://www.trendhunter.com/trends/poly-smooth-collection) and Japanese retailer STUDIOUS have expanded their ongoing partnership with a Spring/Summer 2026 capsule built around the brand's Poly Smooth trackwear series. The collection introduces two exclusive styles that adapt familiar NEEDLES silhouettes for warmer temperatures. A new Track Short Sleeve Shirt replaces the traditional long-sleeve format with a lighter, more seasonal profile, retaining the athletic character associated with the Poly Smooth range. The release continues the collaboration's focus on reinterpretations of established NEEDLES designs rather than entirely new product categories. The second piece is a modified version of the [H.D. Track Pant](https://www.trendhunter.com/trends/hd-track-pant), one of the brand's most recognizable silhouettes. For this capsule, the voluminous shape has been shortened into a knee-length short while preserving the distinctive wide-leg proportions that define the original design. The NEEDLES x STUDIOUS Poly Smooth capsule launches on June 4, 2026, exclusively through STUDIOUS.
