How does Build-A-Pack work?

Our team is listening to you and your concerns. We're aware of the issues with our previous rewards program and can only improve with honest feedback. As a small business, we're grateful everyone has been vocal.

Based on the feedback from our customer base, we have decided to end our current rewards program. We will be exploring a new approach in the coming months that will not only benefit our amazing customers, but will be user-friendly.

This change will not have an effect on our Build-A-Pack program, which will continue to be available to all customers returning customers.

If you have any concerns about this change, please do not hesitate to reach out to our customer service at contact@sheathunderwear.com. They would be happy to help!

For this reason, we recommend only ordering a single pair for your first time trying our products to see if SHEATH is right for you.

SHEATH is for anyone looking for breathable support and separation in their underwear. Give us a try!

Is SHEATH for me?

Take a look at our sizing chart below! We understand some people are in between our sizes, in which case it is advised to size up for a more relaxed fit or size down for a more snug fit. For the best fit with SHEATH, it will depend on your build and if your weight fluctuates. If you're of the slim and lean body type with thinner thighs and smaller butt, keeping to your usual underwear size is advised. If you're on the broader side with larger thighs and butt, you may find a size up to your liking. SHEATH should fit like a second skin - snug, but not tight, allowing the isolative pouch work its supportive magic.

How do I find the right size for me?

Our underwear is available in a variety of cuts, designs, pouch types and fabric types. Below is a quick guide to our underwear catalog. For additional information on a product, please visit its product page linked in the descriptions below.

What's different about each type of SHEATH?

SHEATH is primarily crafted using our signature 92% Modal / 8% Elastane fabric blend. Modal is a semi synthetic material made from the beech tree. It is an antimicrobial, breathable, and very flexible material. It is exceptionally soft, drapes well, resists creasing, and has a smooth lustrous finish. Because modal is both absorbent and air-permeable, it remains cool to the touch in even the most stifling heat.

In addition to modal, we have expanded into other fabric options for select products, such as Polyester, AirFlow Polyamide Mesh, and Bamboo.

What are SHEATH products made from?

Yes, the pouch size increases slightly in proportion to the underwear as you go up in sizes. However, the width of the pouch does not change.

Do pouch sizes differ?

For longevity of our product, we recommend you wash them separately in cold water and use the lowest dryer setting to protect the elastic and material. If you need MORE cleaning power, you can use Vinegar for its disinfecting properties. One delicate cold vinegar cycle and then a delicate cold detergent cycle.

To best preserve the elastic, line dry your underwear, or lay flat to dry. If the waistband is rolling or anything has torn/ripped, then you could be in the wrong size, or the material was damaged due to heat from your dryer.

How do I wash my SHEATH?

It was in 2008 during the sandstorm of the Iraq war, when a United States Army Sergeant Robert Patton, in Camp Speicher, Tikrit had a vision for an innovative design of underwear; SHEATH. This underwear would have a pouch sewn on the inside of the crotch area and would eliminate the balls from sticking to the inner thigh. A simple concept. By separating the balls from the thighs, future irritation from heat, sweat, and friction would be canceled. 

Two prototypes were made without delay in Tikrit, Iraq that summer. Years then passed including a soft launch of sheathunderwear.com in 2010, an honorable discharge from the Army in 2011, and a year of training with a professional tailor from Vietnam in 2012. Then in 2013, SHEATH launched a Kickstarter which successfully crowdfunded the once flagship SHEATH 2.0, which is no longer an option to purchase as it has become obsolete due to further innovation.

When was SHEATH invented?

SHEATH was invented out of necessity; the mother of invention. The hottest place of the body is the groin which can become irritated from heat sweat and friction. This irritation is resolved by the soft, flexible, cradle-like pouch which separates the boys from the inner thighs, eliminating any sticky situations.

Why was SHEATH invented?

SHEATH are built by our expert teams of artisan tailors and crafters in the historical Chinese provinces of Guangdong and Zhejiang. To learn more, visit Our Factories.
