308 GSM Sweatshirt: GRS Certified Recycled Streetwear Boston

Subject: Heavyweight Fleece Selection (500 GSM)

Sourcing Reality: This garment represents a curation of existing supply chain logistics, not a proprietary engineering breakthrough. We selected the heaviest available blank to maximize thermal retention.

Material Specification: 500 GSM Cotton/Polyester blend.
Trade-Off Analysis: We prioritized tensile strength and abrasion resistance over biodegradability. Consequently, this product relies on synthetic binders. While this extends the functional lifespan of the garment, the user must accept the reality of microfiber shedding during wash cycles.

Conclusion: A utilitarian choice for durability, devoid of 'eco-savior' narratives.
