Product & Care


Our design focus is on fit, comfort, aesthetic delightfulness, and repeat use. In fit we strive for neutral form that softens gender boundaries and makes a modern look. For comfort we look at the fabric hand, weight, softness. firmness, stretch. elasticity, color and surface wear. In aesthetics, we push to break away from the traditional notions of what underwear looks like yet work within the restrains of practicality. That means we keep in mind that it's base layer apparel, lives underneath and can not get too dimensional, has repeat intimate skin contact so materials should be gentle and unintrusive, performing over time and withstanding repeat care. 

Tip: In adding items to cart, strategize your selection based on how much wear you'd like to get out of the item. More simple designs naturally will last longer so consider adding a few more of those. Balance the practical with fun ones. Though these will have by a few months shorter life cycle, don't underestimate the delightful moments of touch children experience as they develop tactile and sensory palette. Discover fabrics and textures with them and nurture design sensibility.


Each item is made by me in Los Angeles, sewn with my own hands in limited runs. We are starting to grow and at times it becomes very demanding. Thus we've started thinking ahead and planning for additional capacity. 


Our styles typically share the same base. We'll use patternmaking to creatively differentiate styles and experiment with layering surfacing, textures and elements.

Tip: We recommend going smaller as fabric will give and stretch a little over months. If you know your child is a smaller percentile of the age group, buy a size smaller. If they are within the size range and on the bigger side purchase for that age group. If you are in between sizes, go smaller than larger unless your child is consistently in the larger percentile for their age. Generally refrain from buying big since both the pattern fit and the material will provide room over time.

Bamboo Rayon has swooned us away with incredible wash performance over 5 years of testing a variety of materials. This fiber's ability to retain color, hand, comfort, strength is the main reason why we choose to make most of the underwear styles with this fabric base. We love it as parents and our repeat customers applaud it too for it's feel and resilience. It takes dye very well and has strong vibrant colors. Kids go through different boosts of growth periods. This fabric easily lasts 1-1.5 years because it washes well but also because it stretches. Bamboo Rayon is known for it's tendency to stretch, to account for that we've adjusted all fit patterns fit more snug. Note, never buy big, always get true size. This allows the fabric to give just enough over time to grow with the kid. The fact that the underwear lasts longer in fit and appearance means that families save and dispose less.

Organic Cotton is grown from non genetically modified plants, grown without the use of any synthetic agricultural chemicals such as fertilizers or pesticides. It's an option for kids with sensitive skin. The colors are soft and muted, the stretch is moderate. This fabric easily lasts 0.5-1 year depending on growth.

End of the underwear can be identified either aesthetically by it being too washed out with expected wear and tear or by fit. When the child has grown out of the size, the underwear will stop providing full coverage on the back simply because it's being stretched too much horizontally in width and stops allocating vertical stretch. You'll see kids pulling underwear up which results in underwear riding up. Both are signs for the need to go up a size.

Don't trash your underwear, yet! Send it back us to recycle. We'll welcome it and put it to use so more fabric can be made from these. Help us track lifetime and performance so we can continue to improve and control the environmental footprint. 

Tip: Please send washed underwear and in return we'll thank you with free domestic shipping to be used for your next purchase < applies to wolf industries website domestic purchases only >.


Before we jump into product care, let's quickly cover what you can expect from Wolf Industries underwear. Most importantly fabrics and trims should not bleed or run. We invest in high quality bamboo and organic cotton that should not cause coloration. Pilling should be very minor, observable at the very end of the product cycle. We test wear and washing of all styles. In the case that you observe dying please report it so we can investigate. 

Tip: See shared testimonials we've received to date. Send us your feedback on your family's observations on washing and wear, we'll be grateful.


Being humans and parents in an ever changing world means we are learning new things all the time. We were extremely grateful to Jolie Kerr for fresh coverage on cleaning processes and products that add a level of science and spectrum to our recommendations below.
  • Laundry can be play. Invite kids to participate and learn about taking care of themselves, like brushing their teeth or making their bed. Have them separate lights from darks. Treat detergent duties carefully to avoid contact with kid's sensitive skin. Have them press big buttons! If it's not that kind of day and you want to run solo, totally cool. We get it.
  • Have a delicates pile. Wash our underwear with other intimates, sports and baby wear. All of them have stretch fibers that tend to be sensitive to harsh washing. 
  • Stick'em in protective mesh bag. Keep your delicates away from getting tangled up with bulkier items and getting streched out. We recommend MIU color from Amazon.com which is good for washing under 10 undies. If you are washing more, you might want a larger back so it's not full and water flows easily through it.
  • NEVER use chlorine bleach & go with mild detergent. Use mild detergent in right proportions to avoid detergent residue build up which can lead to butt irritation. 
  • Opt out for cold water and gentle short cycle. As Jolie reports: "cycle speed and force set how your clothes are agitated in the wash. A regular cycle is fast/fast, meaning that both the washing and the spin cycle, which extrudes water from the clothes post-rinsing, are fast. Permanent press is a fast/slow cycle, meaning that the wash cycle is fast, but the spin cycle is slow, which is the best choice for fabrics like rayon or polyester. Much like its dryer counterpart, permanent press on a washing machine will reduce wrinkles because of the slower spin cycle. The delicate cycle is a slow/slow cycle, and the one that should be used for fine or delicate fabrics, or items with embellishments. Cycle length is just what it sounds like: how long the machine is going to be on. Heavily soiled and bulkier items should get a longer cycle, while less soiled and delicate clothing should get a shorter cycle." Who else could have said that better! 
  • For extended life and no shrinkage, air dry. Lay it out on a towel or hang on a drying wreck. Once dry, fold in half and neatly store away. Our process shows you can get so much more wear and product life when you skip the dryer, this means you save money disposing less. If you must machine dry, Jolie recommends to "use a low-heat dry cycle. It's ideal for delicates or items that are prone to shrinking, or for clothing with embellishments that may melt or warp due to exposure to heat."


A few steps to for cleaning body stains (blood, sweat, poop, pee, else), grease stains (butter, oil), food & fruit stains.

  • Start with a quick wash by hand or in gloves.
  • Add delicate detergent to the basin.
  • Fill basin with room temperature water.
  • NEVER use chlorine bleach. Add a soaking agent such as laundry booster, stain remover or some mild detergent. Fresh stains are easy to take out and don't require much. 
  • Run water through both sides.
  • Insert article to be washed and soak for 15 minutes minimum.
  • Repeatedly squeeze undies gently to incorporate water and soap through fibres till it's clean.
  • Pull article out of water and press down on undie to push out excess water. Never wring the undie to extrude water from it which will twist and stretch fibers. 
  • Moisturize your hands if you had contact with detergent.


When potty training babies, you'll have one or two underwears you'll end up throw away, it happens. For mild accidents have ziplock bag handy both for day care providers as well as family outings around town. It might be easier to use specifically designed training underwear for outings since they can get heavily soiled and it might take some time before you get to sink which could result in stains. Keep Wolf Industries undies for fun usage such as running around at home since it's easy peasy to rinse immediately when something happens. 


Wolf Industries underwear does not utilize swim fabric yet nor is it tested as a swim product. If you let the little butt run around splashing, make sure to rinse the underwear after to preserve the fabric. Fresh water (lakes, rivers, oceans) will always go easier on the fibers than chlorinated water (swim pools). When rinsing, press to release water, be careful not to twist to avoid stretching fibers.

If you notice over time white or lighter colors yellowing, Jolie shares "that's due to a combination of chlorine damage and a buildup of skin, body oil and sweat. If yellowing is a thing that you notice is happening, dissolve a half cup of baking soda in about a gallon of cold water, soak the undies for 1-2 hours, then rinse well and air dry. Pilling becomes a problem, you can use this KnitPicks tool to rid of those ugly pills. For sunscreen stains use lemon juice and salt or White Brite. The White Brite will also help to restore suits that have yellowed so badly that the baking soda method isn't powerful enough."
