Bamboo Underwear?

Bamboo; The Natural, Sustainable Choice

As the worlds fastest growing plant, covering huge grassy areas and needing zero pesticides, fertilizers or additional water to grow, bamboo is the ideal choice for a more sustainable way of clothing the planet!

Kinder to the environment, bamboo plants can be harvested without damaging established root systems and can absorb up to 35% more carbon dioxide than trees.

The Ideal Material For Underwear

Bamboo viscose is the ideal material for underwear; it's great for the skin, exceptionally soft and gentle and when combined in our special bamboo and elastane blend it's incredibly stretchy and forgiving.

The gently rounded fibres derived from bamboo plants are spun to create a material with a silk like touch that is wonderfully soft and kind to your skin and it's natural, inherent antibacterial and hypoallergenic properties keep you fresher and healthier.

The Boxers are very pliable and easy to get on which is good for me as i have a crushed nerve in my spine which hinders me when I try to bend my back. They are also very comfortable to wear and don't make me sweat or chafe.

Previously bought bamboo boxers from another company with an Italian sounding name, and they are thicker fabric and better made than the ones from Spairs, which are thin, not very supportive and one pair had poor stitching out of the box. The Spairs ones were less expensive, but really not worth it. I will buy more of the first ones.
