Features Of Our Flannel Underwear Multipack

Each pair of boxer shorts in this flannel underwear pack comes in a different coloured flannel pattern. You'll get red, blue and green boxers to match your underwear to your outfit or your mood! The choices are all yours with this multipack set. 

Our men's flannel underwear is made with our very own Technical Wicking Active Technology (T.W.A.T.). This makes each pair of our boxers quick-drying, breathable and comfortable. We've also added a bamboo baw pouch to keep 'em tidy, whatever you get up to! When you buy a pair of our men's Cool De Sacs, you're getting:

  • Technical Wicking Active Technology
  • Underwear made from Recycled Materials
  • Plastic Free Packaging
  • Bamboo Baw Pouch
  • Breathable, Quick Dry fabric
  • Bawbags Custom Fit

As a brand, we're emphasising sustainability, and as such, we ensure our production methods and delivery are as sustainable as possible. From 2020, we're proud to say that all new Bawbags Cool De Sacs are now made from recycled plastic bottles, and we only use plastic-free packaging to ensure that nothing goes to waste. 

We want to make sure everyone feels great in their pants; that's why our flannel underwear multipack is available in sizes XS-XXXXL. Need help determining which size to get? Check out our helpful size guide for information on taking measurements and finding your men's underwear size.

If you like these flannel boxer shorts, but you’re not sure about the design, you’ll be pleased to know we have lots of other options. Men’s boxer shorts are available in our Originals and Cool De Sacs Collections.

For a classic selection of block colour boxer shorts you could opt for our super-soft cotton 3-pack. Or, you could try something a little more exciting like our Highland Cow Technical Boxer Shorts
