Merino Wool Thermal Base Layer Set for Babies

Megan W.

Needed a new set as she outgrew her first. She wore it almost everyday of our ten day campervan trip in Washington State. She hates shirts tobe pulled over her head, but this is roomy enough to pull on from the bottom.

Fielding’s first tent camp in Sitka, AK! Her half year birthday was on the summer solstice, and we were able to sneak in the adventure the following weekend. Temps got down to the 50’s over night, just chilly enough for the base layers, beanie and merino wool socks to do what they do best! She loved it!

Mariah M.

Perfect hiking gear. My son was able to stay warm in the early morning when we started hiking and cool as it got warmer. I wore the women’s explore top and was able to nurse my son while we hiked. It was amazing!!! We will be wearing these all year long!

We love our new Iksplor sets for our 5 month old. I bought two 6-12 month sets. It’s all she wore on our first camping trip. It kept her protected from the sun during the day and she stayed perfectly cozy at night in the camper. The fit is great because they are nice and snug, but I can roll the pant legs until she grows into them more.

This set is a game changer. Beautiful bright color, soft and high quality - kept her warm and a happy camper. 1st camping trip a success!

We took these base layers for a test drive camping and hiking in Great Sand Dunes National Park. They got dirty, and wet, but cleaned up easily and dried quickly so baby could wear them for sleeping. They have since been on two other camping trips and a handful of family hikes and we have ZERO complaints. When it's warm baby is comfortable and cool, and at night she is toasty warm. I love how easily they clean up and still remain soft and stretchy. We're going to buy a larger size when they are back in stock and I'm considering a pair of the adult ones for myself. What an amazing product and great value.

We’ve used these from hiking to tummy time adventures & we absolutely love them! We’d wear these to sleep if we could. Great quality and fantastic customer service!

Amanda B.

We absolutely love this merino wool set for our daughter. We wore it all winter, into spring, and it kept her warm without a bunch of additional layers. The fit is as perfect as the colors :) You will not be disappointed.

Melissa O.

Perfect weight to keep baby cool in the heat of Utah! Had to rinse / wash it out one night and it was dry by the morning just by hanging it in the bathroom. So glad we purchased this before our trip!

Sheyna R.

I love these base layers for my little girl! We hike a lot, so she gets a lot of use out of them. They seem to keep her warm or cool depending on the weather, and go great under a fleece or winter bunting if needed. I just ordered the raspberry color which we can’t wait to try out. I ordered 6-12 month size so they would last longer and she’s been wearing them since 5 months. Definitely a little big with room to grow, I just roll the cuffs!

As a parent I am always looking for new gear to keep my son nice and comfortable on adventures and honestly my son is loving his iksplor merino wool set kept him nice and warm on multiple trips and no stinky odors after wearing the set for 3 days, and no complaints about being itchy.. I would definitely recommend this set to a parent looking to purchase a good merino wool set.. Can't wait till they drop a line for us fathers.. I will definitely be buying when they do...

Best thing ever! I love having a solid layer to put my baby in for hiking and just everyday wear. So soft and fits great. I plan to keep buying for years to come.

Brighton P.

We LOVE these! My baby wears them as a baselayer in the winter under his snow gear, and in the spring, summer, fall as PJ's and just an outfit to hike in! Such soft and strechy fabric. LOVE!

Erin B.

Perfect outfit for summer hikes and base layer for winter adventures!! Such great quality and have gotten so much use. Absolutely worth the price and recommend to all my friends!

Maria T.

This was purchased as a gift.... so even though I love it Not sure what the actual recipient thinks!

Cayleigh S.

Great quality! It fits snug in the torso and waist so the 6-12 month fits my 4 month son (who wears 6 mo clothes) well, I just have to fold up the sleeves and pant legs for now but it should fit him for a while yet.

Lauren K.

We wear our base layers every weekend for mountain adventures, and they’re just perfect! Nice and cozy under our bunting layer, and comfy for hanging around the house.

Kelly D.

We just took my 3 month old on her first camping trip, and this set was perfect. It worked great as a warm and cozy base layer (see it under her sweatshirt in the picture). I really appreciate that it has mittens. The 3-6 month size fits her perfectly, and probably will for a little while. It gave me peace of mind that she wasn't too cold, since it got cold at night.

Hailey T.

LOVE these base layers! They’re great for layering in the winter, but also for those sunny hikes. I took my four week old baby to Death Valley and have her wear these baselayers the whole time to protect her skin since she can’t wear sunscreen. They are thin enough that she didn’t overheat but was totally covered. Love them!

Daniel B.

Great set and love the baby blue color!

Linda S.

Quality clothing and excellent customer service! Doesn’t get any better than that!

Whitney H.

Lots of winter adventures from hiking, skinning, cross country and more with little one in tow

Meghan J.

Since receiving our little one constantly ends up in this outfit from going out on a hike, to romping in the snow, and indoor play. We are on to buying our second set as no other clothes are quite this versatile and durable!

CHRISTA D.

Live in central MN. Needed something to keep my babe warm when we went hiking, walking, and off to the dog parks. We got this around 4.5 months and he’s growing into it nicely. He doesn’t fight putting this on! ⭐️⭐️⭐️⭐️⭐️

kaajia c.

My kids wear their sets as loungewear/pajamas around the house because our downstairs is a bit chilly. They are adorable and cozy - we want more colors!

Marissa M.

We are loving this iksplor set for our son! I was searching for good merino wool clothing for him to wear during our winter activities here in Salt Lake City since we didn’t have a good base layer for him yet. I was hesitant at first due to the price but it has definitely been worth it and he still has so much room to grow with it. From Nordic skiing, alpine skiing, sledding, and hiking.. this is our go to! I love that it has hand covers because my son never keeps his gloves on while in the backpack or the chariot. Whenever I pull him out, he is always toasty and warm! I 100% will be buying the maternity/nursing pair for myself on my next pregnancy! Awesome company, thanks for making a great product.

Brittany B.

Keeps our babe warm and cozy!

Diana W.

My little is so comfy and warm in these base layer. Even better she loves wearing them.

Karen C.

This is the best wool clothing for infants! Super soft and natural warmth that doesn’t make them overheat. Will continue to buy from this company!

Tiffany S.

The best gear for playing in the snow! Soft material, easy to clean, and great to layer. Customer service was so helpful. I ordered the wrong size and within a few days had a different size mailed to my home. Love this brand!

marissa r.

My little man loved his set and so did we! It kept him warm and his movement wasn’t restricted which was awesome for this new crawler. The color is so adorable and material so soft!

Tamara A.

Wore it to a camping trip. Sophie was warm and cozy the whole time

Allison H.

This kept my 5 month old nice and warm while camping. I’m so happy I bought it! I wish there was an option to purchase a long sleeved onesie, because the top would bunch up on him.

Allison B.

We used it this weekend to backpack into Haleakalā, Maui this last weekend. It worked great! I love how soft it was and how it helped keep our baby super comfortable while being carried.

Eden D.

I've already removed 3 stains from it so far and there are no traces of any of them. The material is so soft and we love the little hand covers! He's a hot baby on the coolest of days and he doesn't get overheated in these at all when we are on the trail, which is saying a lot! This is such a great product, and I will be getting him the size up as soon as the time comes!

M M.

My niece absolutely loves her Iksplor set! She wears its everywhere, and I mean EVERYWHERE, and it still looks brand new after every wash. The color is still rich and so cute on her. Amazing product!

Julia

The Iksplor Merino wool base layers sets for both my toddler and baby are PERFECT and exactly what I was looking for when searching for outdoor adventure wear. I don't need to worry about the sun -because they are up to 50+ UPF. They are super soft on my kids' skin (especially my baby). It takes a lot to get them wet (which is great for our humid Hong Kong monsoon weather and chilly damp winters). The colors are divine, and I can feel good about how they are sourced and where they will end up when we're done with them. Awesome products!

Hailey T.

Merino wool is my absolute favorite material for baselayers so I had to get it for my baby. I love this set so dang much and my baby does too. He has worn it out in the freezing cold and at home for nap time. It’s soft and comfy and makes this mama happy that her baby has the best quality baselayers out there!

Heidi B.

These layers are perfect year round. Whether romping around outside or snuggling indoors, they are comfortable, versatile, and colorful!

Lynzy T.

so cozy and warm! perfect for base layers or a cool fall day in the mountains. and the perfect jammies for camping! Also love the colors so much!

Ellice J.

Birthday gift for our 2 year old grandson

Blair

The iksplor set is an essential piece in our daughter’s wardrobe! These keep our daughter warm on cold nights camping or backpacking, and cool on hot days hiking.

Lindsay L.

LOVE these base layers SO MUCH for my 9 mo old baby boy. Perfect for cold to warmer days and last well beyond the monthly sizing. Superb quality and comfort - my go to, pretty much everyday.

Kristina M.

Again colors are fun. Good quality merino

Kristina M.

No baby yet. Love the bright fun colors . Good quality

Phil M.

The Iksplor base layers are a big hit. Nice work! So well made, and such a great presentation in the bag. Well done and thank you!!!!

Kim H.

As 5th generation Outfitters based out of Wilson/Jackson Hole WY, our gear matters to us and we pack carefully and concisely. We love this blanket and we love merino wool for adventures, mountains, beach, and travel. It is versatile in more ways than you can imagine. It is soft, cozy, well-made, drys quickly. Highly recommend this product for adults and kids alike.

Amelia M.

As a family with kids who essentially wear base layers 24-7 all winter long, we are always on the look-out for ones that are comfortable, warm AND durable. Iksplor has nailed it with pieces that the kids love to wear, are easy to wash and maintain and put up with some serious abuse. We also love their hats that fit great, are double layered and stay on and neck warmers for just a little extra warmth to keep us outside longer.

Stephanie R.

Iksplor base layers have been a life savor. My 3-year-old daughter has severe eczema and the base layers have been so helpful in controlling her itching and flare-ups. They fit her perfectly and she loves them so much that she wants to wear them to bed every night, even in the summer. They are washed (and dried) frequently and still look brand new. They are the perfect base layers for Jackson Hole adventures!

better travel, easy care

Iksplor layers are perfect to pack on any trip. They are lightweight, resist odor-causing bacteria which means your iksplorer can wear them longer without the stench, and they're machine washable.

better adventures

Merino wool is the perfect next to skin layer for every adventure, yes even WARM ones. It's temperature regulating qualities keep your little iksplorer warm when it is cool and cool when it is warm. Wet pants? No problem, merino wicks moisture and dries quicker than synthetic fabrics.

better for the planet

Merino comes from our wooly friends, the merino sheep. Unlike polyester and synthetic clothing that end up in our landfills for 100's of years, when the iksplor layers are at the end of their trail, they can be composted in 6 months.
