Thunderpants organic cotton and spandex fabric is super stretchy, comfy and easy-fit. There’s no nasty, scratchy elastic that digs in. They are the ultimate comfy, easy-fit undie.
The flat fronted original, hipster and sky rise styles all have the same fit through the leg and butt varying in height. The hipster is low waisted, the original sits around the navel and the sky rise is high waisted.
The flat fronted boxer is a hipster fit with a short boy leg.
See the size guide below to help you choose the right size. If you happen to fall between the measurements, don’t panic! We recommend going up rather than down a size.....they will last longer and be more comfortable if not stretched too far.
The swimwear also follows this standard New Zealand sizing.
This chart includes all styles in the adult range that are not a pouch front but does not include the Cotton Drill A line skirts whose size chart is included in the product description.
| XS | S | M | L | XL | 2XL | 3XL | |

| waist cm | 62-72 | 72-82 | 82-92 | 92-102 | 102-112 | 112-122 | 122-132 |
| hip cm | 76-86 | 86-96 | 96-106 | 106-116 | 116-126 | 126-136 | 136-146 |

| waist inches | 24-28 | 28-32 | 32-36 | 36-40 | 40-44 | 44-48 | 48-52 |
| hip inches | 30-34 | 34-38 | 38-42 | 42-46 | 46-50 | 50-54 | 54-58 |
These styles are exactly the same in every way except the hipster is shorter in the waist than the original or sky rise. Those of us that have a bit of a tummy roll may wish to choose the original or sky high style as they cover the tummy.
The pouch front boxer is the closer fit option. If you like everything snug with a fitted boxer leg then opt for the boxer. For those that prefer a looser fit, stick with the brief.

NEW ORGANIC BAMBOO
These delicious soft & silky bamboo elastane sky rise these are so much cooler than our previous Bamboo/Cotton fabric. Because there is no cotton these have much better drying and wicking properties than the navy, so even better for travelling.
NB: Photos are of models wearing sky rise style in our usual cotton fabric, actual garment made from a sleeker more silky bamboo fabric.
SKY RISE THUNDERPANTS, an extra high waisted version of our originals. They are a very comfortable full brief that sit high on your natural waist and taper in at the top, so stay right where they are meant to all day long.

| leg band inches | 16-27 | 17-28 | 18-29 | 19-31 | 21-33 | 23-35 |
Sit high just above your natural waist and the leg line follows the natural curve of your body just like the originals and hipsters. They taper in at the top with a slightly firmer fit, so will sit and stay right where they are meant to all day long.
This Thunderpants fabric is 93% bamboo & 7% elastane to give it that super comfy, soft stretchy feel. Made locally and lovingly in New Zealand.
To preserve the vibrant colours and life of the fabric we suggest you do not soak or bleach your Thunderpants items. Use a gentle detergent in a cold machine wash and dry your Thunderpants on the line, not in the drier.
Your Thunderpants are not only super comfy but they are designed to withstand some pretty staunch stuff, so get into them and get on out there!

LOVE my Thunderpants even more now I've discovered the "Skyrise" versions! 💖 Perfect for not digging into my tummy, as well as not riding up. They sit around my waist - perfect for no panty lines! 👍🏻 After buying one pair of the soft and slightly thinner material bamboo pants, they will be popular with me during Summer, I can tell. I'm just waiting for them to be restocked! 🤞🏻 Loving the new colours too! 😍 although I do have some plain white ones for under Summer dresses 👗😊
So soft, light and comfortable, these are my fave Thunderpants!
So very comfy. Love my bamboo sky rise. Keep up the good work xxx
Soft and nice fabric, covers everything and feels good on the skin. Stays in place during everyday activities and workouts.
Love, love, love my high rise bamboo underwear! I first tried them as an alternative to the many pairs of cotton thundies that I have, thinking they would be perfect for wearing with jeans in Winter....no more gaps over my kidneys! It turns out that they are perfect all year round! I especially love wearing them with skirts and dresses. They keep my tummy nice and snug!
Love the bamboo! Cool and breathable on those extra hot days.
Great in every way as always
They are now my favourite thundies. Super soft and comfortable!!
Great quality and fit
Silky, well fitting and comfortable, sky high, supportive and gorgeous pink
Beautifully soft, buttery feel. Definitely lighter weight than the cotton thunders. Will go down a size from my usual cotton thunders, as the bamboo ones are roomier. Love love the high waist, sits well under high rise jeans etc, gives a soft lining to waistbands and scratchy labels.
Always rely on Thunderpants to deliver!!
Love the fabric, very soft and so comfortable
I love these lighter skyrise underpants! Perfect for travel and warmer days. Quicker to dry too. Best undies in the world 💚no wedgies 🙌
Soft. Comfy and fit perfectly
Thunderful!
Arrived just in time to pack light for an overseas trip. Love the fabric and shape, fit well and don't roll down!
Love the new lighter weight bamboo undies
SO comfortable!
The lightweight fabric is perfect for summer, especially now that the weather has turned hot. Perfectly fitting, not at all tight, perfectly comfortable.
they feel great
I love the feel of it, but it's too big, and I don't feel it has the same 'safe' feeling as the cotton ones.
Comfy!!!!! Comfy!!!! and Comfy!!!!
These feel great on the skin, warm in the cool weather, cooler than cotton or wool in the hot weather and wash up beautifully soft every time. (I altready had a pair and looked for more.)
Literally the most comfortable underwear I’ve ever worn! I actually forget I’m wearing them, they’re so comfortable! Material is beautifully soft. Please make more in this material :)
A lighter fabric than the usual Thunderpants variety but love them under frocks
so comfy!
I’ve been a thundies fan for years.. I love the original .The bamboo sky rise are everything I hoped they would be. Super comfy,quick drying. Great for travel!
Very comfortable
Comfy and breathable and don't slide down. Perfect for sport
I love these as they are light but still hold me in. Great for those really hot days!
Quality and comfort for a pear shaped person :-) what more does a 65 year lady need.. amazing!
Just perfect!
Love the bamboo undies - they fit perfectly and are light and comfortable. They dry quickly too
These are awesome (th)underpants for summer in Australia. I am allergic to latex, and these are the coolest latex-free underpants that I have been able to find. Thank you.
.
I have an ileostomy stoma bag which means I am always looking for waist bands that go above my belly button and over my bag which is why I love the sky rise and your bikini they both make me feel comfy and confident. Thank you
Stretchy, comfy, high enough, low enough, barely there. May need more!
The briefs r lovely to wear. It feels almost as tho I'm not wearing any they r so light and comfortable. As soon as there's more stock I'll be buying more.
Amazing comfort. These are even better than the normal thundies. How do you improve on perfection?! I don't know, but you've done it. Thank you 🙏
