Sizing way off

Based on sizing guidelines, I ordered sized medium boxer briefs (which is also in line with what I’d buy from other companies). When they arrived a couple weeks later, I went to try them on and couldn’t even get them past mid-thigh. They weren’t a little tight - they were WAY off. It makes me question the sizing guide and future purchases. Additionally, the whole “free returns” we’ve become accustomed to does not apply - expect to pay for shipping & handling and a processing fee. Overall not a great experience and I likely won’t be ordering from them again.

All that being said, the customer service folks were very pleasant and professional in communicating with me. I hope they can get the sizing issues figured out.

Hi Timothy! We apologize for the sizing issues you experienced with your recent order. We appreciate your feedback and are actively working to improve our sizing and processes to ensure a better shopping experience for our customers. We also understand your disappointment with the return process and fees. We are constantly reviewing our policies to make them as customer-friendly as possible. Thank you for your kind words about our customer service team. We value your feedback and hope you'll consider giving us another chance in the future.

Great lightweight underwear

I was wearing brooks brothers boxers. They were Pima cotton. These are much softer and a little shorter. They are perfect. It’s like wearing nothing. And it’s so much softer than the Pima cotton. I’m definitely glad that I went all in and bought 8 pairs.

That's fantastic to hear! It sounds like you've found the perfect boxers for you. The softness and comfort of these compared to the Pima cotton must be a real game-changer. I'm so glad you went all in with 8 pairs—it’s always a win when you find something that feels just right. Thanks for sharing your experience!

Outstanding

Best pair of underwear I own. I like them better than my Duluth Trading Buck Naked for several reasons; they are made of Alpaca a much higher quality material, they don’t make me sweat, and they don’t stink.

Thank you for your feedback! We're thrilled to hear that you love our underwear. It's great to know that the high-quality Alpaca material, along with the comfort and odor resistance, has made a positive impact for you. We appreciate your support and look forward to providing you with more products that you enjoy.

Amazing

Garmet feels durable and well made. All natural material that thermoregulates your body temp. Stretches and looks great.

It's wonderful to hear that you're pleased with the boxers! :D

First timer.... beware

They lure you into over buying for free shipping. The sizes were inconsistent between pairs, 3 fit great, 4 fit not so great. I would go larger in size if you are dead set on these, but I wrote the company in hopes of a solution... none was given as the company has not even responded to me. No refunds or exchanges on sizes.

Love the material otherwise!

Your feedback is incredibly valuable to us, and I apologize for any inconvenience caused by our lack of response. We strive to provide exceptional customer service and will investigate why your inquiry wasn't addressed promptly. While we don't offer refunds or exchanges on sizes at the moment. I'll ensure your concerns are noted for future improvements. I'm glad to hear that you love the material. We're here to help.
