Superfine merino that's gentle on sensitive skin. No itch, just comfort.
Keeps kids cool when it's warm, warm when it's cool. Built for every season.
Machine washable and dryer friendly, built for busy families and messy moments.
Your kid's next-to-skin layer is the most important! Designed with extra length to keep up with growth spurts, it keeps kids comfy through sun, snow, and everything in between, so adventures last longer.
Merino comes from our wooly friends, the merino sheep. Unlike polyester and synthetic fabrics that sit in landfills for hundreds of years, this nursing hoodie composts in six months instead. It's 100% natural merino wool, renewable and biodegradable from sheep to soil.
Yes, 100% Responsible Wool Standard (RWS) certified merino wool. No blends, no synthetic fillers, just the real thing.
Not with this merino. Superfine fibers are soft enough for sensitive skin, with none of the itch people associate with old wool sweaters.
Both. Merino regulates temperature naturally, so it works on cold mountain mornings and warm summer nights alike. Plenty of Iksplor kids wear theirs as pajamas all year round.
Yes, that's exactly what they're built for. Soft, non-bulky, and warm enough to wear on their own or layered under snow pants on the mountain.
True to size, though they run a little long in length, so there's a bit of extra room to grow into through a growth spurt.
Yes. Send them back through Iksplor More for cash or credit, giving them a second life with another adventurer.

My daughter wore this all day at Silver Dollar City! She got wet, the weather got warm (probably near 80°F), and the sun shone all day. She said if she did it all again, she'd still wear the shirt! She kept the sleeves down, didn't get too hot, and didn't burn. She just wishes I'd bought her the shirt in purple. 🤣🤷♀️
My 4 year old only wears wool so this has been a lifesaver!!! I can get out the door and enjoy the outdoors :-) he is wearing the baselayer and midlayer on the rock photo! Pretty cold weather
We purchased a size 2T for the top & bottoms. Our kiddo is a year old. They keep her so warm on our hiking adventures under her bunting & I wish we would’ve purchased them a little sooner. Looking forward to testing them out for our future backpacking trips! I love that the top has thumb holes for keeping it on while tossing a jacket over her!
This baselayer set is so top notch -- my girl has lived in Iksplor since she was a baby; now we're loving the toddler shirt and pant set. Its so nice to be able to go from pajamas to outdoor layer and back to nap and bed when needed on trips!! You can definitely tell this brand was built by moms.
Love love love! These keep my boys SO warm at forest school in the winter months! And enough for them to strip down to when the sun comes out but it’s still cold! The perfect under layer. And the 4T fits my 3 yr old and the 5t fits my 5 year old perfect (both with a little room to grow!)
Fiona was so excited about the bright pink color and they kept her cozy and warm her first couple days skiing this year! Photos are pre ski day and apres at crested butte.
Our go-to camping clothes! Perfect for the days that fluctuate from 30s to 70s & my daughter loves them too!
Whether it’s an 80-degree summer day or a -14° winter storm, our girls are always rocking their Iksplor baselayer top and leggings. I bought our first set for my oldest back in 2021, and they’re still going strong! We have them in so many sizes and colors because they get worn all the time—under dresses as leggings, as ski baselayers, for sun protection—you name it. Huge bonus: they can be washed and dried! Every outdoor kid needs a set of Iksplor baselayers.
We've been using Iksplor baselayers on adventures since our little girl was 3 months old, and I couldn't recommend anything better. From the next-to-skin fit, to the fun, vibrant colors, they're just the best! Thank you for making beautiful, functional clothing.
We love our new cozy base layers, they really are easy to clean (necessary with a toddler), I love that they keep my girl warm, and I also love that they’re 100% merino wool!
We love our Iksplor baselayers and hat! Her first set was when she was newborn and we just upgraded to the 4T. She is able to wear it in the summer to protect from the sun as well as in the winter to keep her warm. Everytime she grows out, we will be purchasing a new one :)
Beautiful and functional - my kids always pack this into their backpacks as their most important piece of clothing for any of our adventures. It’s the absolute best ❤️
We love our Iksplore sets so much!! My daughter is small for her age, so we finally just sized up to 3T at 2.5 years old (23lbs). This will be our third set and she picks pink every time. We’ve more than got our money and use out of each set. I just started to notice she snagged the butt of the 2Ts, but it was after heavyyy use! I know they have patches you can buy too. Anyways, worth the buy and we’ve been very happy with them, whether we’re hiking, backpacking, skiing, or just exploring outside!
Goodness my daughter looks edible in her little Iksplor outfit! Excellent fit, perfect base layer to keep her warm at night and while she's running around during the day! We love it so much!
The best baselayers ever! They keep my boys comfy and warm/cool depending on the weather. We use them for skiing, camping, hiking during the entire year. My boys love the color options too!
Love these Iksplor sets! They are durable and comfortable. My kids love hiking, camping, and winter cabin trips in these.
We love our Iksplor merino wool! Not only do we have them for our kids but I got myself a pair this summer and absolutely love them. My toddler loves the finger holes and I love that I can wrap it over my baby's hand in the winter time. We wear these year round- every ski day, time in the snow, camping... They are the best. Also make for a great baby gift for your adventurous friends/family members who are expecting.
Unfortunately my toddler cannot tell me if she loves it or not but these feel very soft comfortable, lots of room for growth. She seems pleanty comfortable in the pack, down by the river and at home when she wears the iksplorer set.
Warm enough for blue sky cross country days with just a vest. But the real reason I love it and am buying the next size up (storing this size for the little brother!) is that we had a week of no power or heat after a storm in January. My 7 year old wore these essentially 24 hours for a week. He stayed warm, never itchy, and by the end there was still hardly any odor despite cross country skiing for miles several of those days!! Impressive.
My grandbaby keeps asking for “blue jammie long johns.” ❤️
Just his Iksplor base layer was perfect on a spring afternoon on Mt. Bachelor.
Our caboose loves her iksplorers!!
My daughter does not fight getting into these long Johns! Great base layer for under her snowpants and jacket when we play in temps under 20 degrees F. They are worn in the house before/after outdoor adventures. She did get a small tear in one knee which I repaired easily; I think overall they’re a standard legging thickness and she fell multiple times before they ripped. They do not give her a rash (unlike other clothes) and are moveable/breathable!
I got this Kid Iksplorer set for my grandson, and it's clear we need a second set! This is the first layer on ski days, and the wool is so soft and comfy that he often wears these as pjs. Photo: Waking in his Iksplorer set at Odell Lake Lodge, Oregon Cascades, to fresh new snow falling--and calling us to the slopes.
We love our iksplor gear - it’s basically our ski uniform all season long. Thanks for all you do to make sure our kiddos get out during the winter :)
Both my sons love their baselayer sets and the thumb holes are so awesome to have as well!! My younger one is obsessed with Sonic so he wants to wear blue all.the.time! That’s also a feature I love, is that they don’t need laundering after each wear! Lifetime customer! Please consider making underwear as well!
My son (21 months) loves his wool base layers. He refused to let me take it off when he got sick. Day one at the zoo. Two days later, he was still in his shirt, and I finally convinced him to take it off. It was cozy and comforting for him. I love the set for warmth, sun protection, layering, ease of cleaning, and multiple wears. I'm not too fond of laundry. But with wool, it keeps me ahead.
Perfect outfit. I don’t have to worry about sunscreen or what weather might come, it’s cozy, comfortable, and even better, super cute!
Our little guy has been rocking these layers on countless adventures...in the desert, up mountains, at home. They are durable, but when the inevitable hole shows up because your toddler feels the need to climb every rock on their own, they have patches that are easy to use too! Love our Iksplor wool layers so so much!
All my kiddos have the sets and they help so much with our high elevation camping! No complaints of being cold at night!
My kiddos godmother introduced us to Iksplor and I’m so grateful! Every morning, no matter the weather, my 2 year old reads books and then goes to play in the backyard and will be outside for the rest of the day. We live in Central Oregon and often get all the elements in one day. These base layer sets have been game changer, I can finally stop packing multiple changes of clothes cause these not only keep him warm but they also dry incredibly fast which is perfect for all of our river playing. He plays hard and is very hard on his clothing but these have held up all fall/winter/spring and we will still be able to use them for his sister next year. Also Iksplor is the only brand that actually fits true to size for him and last, he grew 4 inches and was still fitting comfortably. I recommend Iksplor to absolutely every family.
Merino re-up time!! Someone is excited to get their new color!! ❤️💛
It's hard to see the top in the picture, but my daughter loves her kids iksplorer long sleeve. She wears it all the time, especially we play out in the snow!
My daughter loves her kid iksplorer long sleeve merino wool top. She wears it to play out in the snow and daily around the house too.
These baselayers are perfect for my autistic daughter who has sensory issues with tags and seams! They are soft and the flat seams don’t bother her. They are her new favorite lounge wear and it’s rare for me to see her out of them when she’s at home.
I love the set and the color but unfortunately the pants already have a hole in them after only about five wears.
My daughter wears “woolies” everyday under her clothes. She wanted bright yellow, which is how we ended up buying Ikaplor! She loves the fact that the sleeves come over her fingers. The Iksplor set is now her favorite under layer to wear. The pants are big enough she’ll definitely get a second season out of them!
This is our son's number one favorite shirt (it's the thumb holes, he's obsessed)
So soft and my toddler loves putting these on to go outside!
We love these as a base layer for hiking or camping!
