“Really nice underwear. As a commercial pilot that sometimes spends more than 12 hrs in the seat, this was the most and best ventilated underwear I have tried so far.”

Don't just take our word for premium quality.
“Really nice underwear. As a commercial pilot that sometimes spends more than 12 hrs in the seat, this was the most and best ventilated underwear I have tried so far.”
“Really great product, comfortable to wear and didn't even notice having it on the legs, where generally boxers often come up. The material is really high quality! Recommended and worth it, especially on long days at work.”
“These boxers sit and fit very well. Probably the most comfortable boxers I have ever used. You can barely feel them and even if they curl up they are still comfy. Strongly recommend.”
“The boxers aren't just comfy for work and travel; they're also fantastic for sports! They're like the secret weapon in your wardrobe, keeping you cozy while you're on the move.”
“I had the chance to try out these boxers and I really like the comfort and shape. The material is smooth and fits the body very well. I can definitely recommend these to anyone and especially under a uniform. — Lasse / Business Jet Pilot”
“I'm extremely particular when it comes to underwear. Especially being an airline pilot and sitting down for hours on end. The product that 1st Layers has created with the Aviator boxer is absolutely amazing. I've tried a lot of different boxers over the years but these do what they promise — and they feel great. Top notch work by the boys behind 1st Layers. I'll be ordering more boxers.”
“Första intrycket är väldigt bra. Snyggt paketerat med en proffsig layout. Jag är väldigt nöjd. Skön passform. Har använt långa arbetsdagar utan att en enda gång besväras av kalsongerna. Behövde inte ägna en tanke åt dem. Vilket i min värld är ett toppbetyg för underkläder. Bra produkt!”
“I'm very satisfied with the comfort and quality. I can recommend them for all categories of pilots — airliner, helicopter and fighter pilots.”
“I really liked the packaging — simple, premium, and well thought out. The material feels great on the skin, very soft and breathable. The waistband is especially nice — comfortable and feels high-quality. The overall fit is seamless and light, perfect for everyday wear. The only small downside is that the fabric is a bit more transparent than I expected. Otherwise, the comfort and design are excellent. Definitely a solid choice if you're looking for smooth, lightweight boxers.”
“As a pilot, it's important for me to wear clothing that are comfortable above all. Though the company provides us with a uniform, it is up to ourself to manage underwear. Often we sit still many hours at a time, therefore the importance of good underwear that has stretch and where quality does not go on compromise. With 1st Layer I have found a match. These underwear are breathable, they have a light feel, whilst being good, strong and very comfortable at the same time. A must, for aviators.”
“The Aviator — Lyocell Boxer Brief is easily the most comfortable underwear I've ever owned. The fabric is silky, breathable, and stays cool all day. The fit is perfect, supportive without being tight and the waistband never rolls or digs in. After several washes, they still feel brand new. Recommended!”
“They fit like a glove. Really good breathability and smooth fabric. I forget I have them on!”
“My free sample boxer short from 1st LAYERS performed extremely well on my 8-hour flight to New York — no itching, no sweating, just perfect.”
“First flight tested on Madeira — known as one of the more challenging airports. I can happily report it went smoothly, so if they can handle Madeira, they can handle anything. Super comfortable all day.”
“Wearing them feels like that one favourite piece in your wardrobe — the one you don't use every day, but save for the right moment. A garment you choose when you want to feel refined, a little more luxurious, or simply treat yourself.”
“Incredibly comfortable. Big plus that there's no care label. They don't ride up like most other underwear I've tried. The waistband is slightly slimmer than I'm used to, but not in a negative way. I've walked, flown, stood, and even trained in them — 5 out of 5!”
