<30 miles of hiking, completely disintegrated

I purchased two pairs of these briefs to wear on alternating days while hiking the Pacific Crest Trail and was excited for their softness and the natural fiber's ability to reduce odor. However, within 60 total miles, both pairs were completely useless.

The fabric rubbing between my legs eroded away almost immediately; I noticed the holes at Mile 30, so likely they didn't even last that long. By mile 60, both were completely useless.

Nothing on the company's website suggested the briefs would be ill suited for backpacking; in fact, in multiple places, Arms of Andes promotes the briefs as "The Perfect Underwear for Hiking", saying also that they are "designed for backpacking". Clearly not.

For further insult, Arms of Andes has determined that my case is not eligible for refund or other compensation. I'm not sure what conditions would have to exist for them to consider a product failure their own fault, but this seemed a cut-and-dry incident to me.

So now, I'm out $80 within a matter of days and have no refund with which to purchase replacement briefs. It's frustrating the product was so poorly suited for backpacking, but it's insulting that the company won't stand behind their product. Their customer service has been receptive to feedback but has stonewalled any requests for reimbursement.

Nice but thin

I like the feel and sizing but the part by the bottom middle seam (lower crotch) has worn away and holes have appeared after about 10 wears. Other pairs are holding up with the same use.

Elastic stretching out after wearing only a few days

Arrived Jan 29 and the elastic is already stretching out! Way too much money for the quality. The large runs small.

Hi there,

Thanks for your feedback! Since our garments are made from 100% Alpaca Wool, they are naturally delicate and can show signs of wear over time with frequent use. If you have any questions or need more information, feel free to reach out to us at embracenature@armsofandes.com—we're happy to help!

Buyer Beware

The size chart is not remotely correct so definitely size up at least one, maybe 2 sizes. They also won't accept returns, citing a return policy that is not displayed anywhere on the product page. Their customer service is also very poor, and will take days to get a response.

Hi Dan,

Thank you for your feedback! We really appreciate hearing from our customers—it helps us keep improving.

We do accept returns, but to maintain hygiene standards and stay environmentally conscious, we can only take back items in their original condition. Unlike many brands that discard returned garments, we do our best to reuse materials whenever possible, which is why we ask that items be unworn and unwashed.

Our return policy is always available on our website’s front page for easy reference. If you have any questions, feel free to reach out—we’re happy to help. Thanks for your understanding!
