100% Comfort Guarantee

We know it's impossible to experience GIIN sewn-free undergarments without trying them on. Therefore, your first GIIN undershirt and first pair of boxer briefs are covered under our 100% Comfort Guarantee. If for any reason you are not completely satisfied with our undergarments, we will give you a full refund of the product purchase price (Sorry, we cannot refund shipping). We will not question your decision, all we ask is your feedback to make our products better.

Please email service@giin.style and include the order number to start the process.

Please note:

  • This guarantee only applies to our undergarments.
  • It is limited to one undershirt and one pair of boxer briefs per household.

You may return any items (excluding undergarments) within 14 days of delivery, provided the items are unworn, unwashed or unused, and in original packaging. Please email service@giin.style. There will be no restocking fee but shipping will not be refunded.
