The new Biotope × Haynes product is now available. The neck specification, which is hard to lose its shape, overturns the common sense of pack T!

Hanes for BIOTOP, a special order project by BIOTOP with Hanes, which has always been well-received, has just received news of new products for the spring/summer 2026 season.

One of the problems with T-shirts is that the necks are always worn out.

To solve such problems, this work adopts the "double binder neck" specification, in which the body fabric is sandwiched between neck ribs and sewn with a binder process in a double-layer structure to achieve further resistance to stretching around the neck and high durability.

The fabric selected is 6.1 oz. BEEFY cotton jersey, which is synonymous with heavyweight T-shirts and is considered one of the best signature models of "Haines.

The boxy silhouette matches the tough body, but the shoulder width is not set to fall too far, so it is not loose, as is often the case with relaxed fit garments.

The launch is Friday, April 3.
