Garment Bags

We are using a new technology called Hydropol to store our clothes whilst in the warehouse. We are really excited about these bags. They are a very similar material to plastic, but without all the negatives. They are 100% biodegradable, compostable and breakdown to non-toxic materials. They will degrade when in water over 70C, so we suggest you give this a try when you receive one of our bags. 

Mailing Bags

  • Small items - Paper mailing bags
  • Larger items - Biodegradable sugarcane bags 
  • Very large items - Cardboard boxes

Packing Tape

  • Small items - gum tape (biodegradable)
  • Larger items - reinforced gum tape or brown tape (non-biodegradable)

If you buy any of our army surplus products then all the packaging will be plastic free (except the tape for large items). With army surplus you minimise the environmental impact of producing new clothes and reduce plastic waste. 

With our new items there may be plastic packing which comes from the supplier themselves. 

Although we are not totally plastic free (but pretty close) our goal is to reduce our plastic waste as much as possible and will continue to do so going into the future.
