Merino Wool Swim Trunks
Domesticated by polyester. Gone feral.
Merino wool swim trunks in 100% merino wool. Most swimwear is recycled plastic; this is natural fibre swimwear.
Why it's built this way
Synthetic fabrics shed microfibres in the wash and even while you wear them (De Falco et al. (2020), Environmental Science & Technology). Merino stays warm even when wet and resists odour between swims. We'll be straight with you: wool absorbs water, so it dries slower than polyester trunks.
