Trying to decide which KETL Sun Hoodie is right for you? In this video we compare the Nofry Vent Sun Hoodie, Nofry Standard Sun Hoodie, and the Lost Boys Sun Hoodie so you can choose the best one for your next adventure.
All three sun hoodies feature UPF 30+ sun protection and built in thumbholes for extra coverage during long days outside. They are designed to keep you cool, comfortable, and protected whether you are hiking, trail running, mountain biking, traveling, or exploring in hot weather.
While they share the same sun protection and overall design philosophy, each hoodie has its own strengths that make it better suited for certain activities and conditions.
The Nofry Vent Sun Hoodie is our most breathable option and is designed for extremely hot conditions and high output activities. It features four snap buttons on the chest that allow you to open the hoodie for additional ventilation when temperatures rise. If you are looking for the most breathable sun hoodie for trail running, hiking, or mountain biking in the heat, the Nofry Vent is built for maximum airflow and cooling.
The Nofry Standard Sun Hoodie is the cleanest and most minimal design in the lineup. It uses the same lightweight UPF 30+ fabric and thumbholes but removes the chest snaps for a streamlined feel. A single button on the hood helps keep it secure in windy conditions, making it a great everyday sun hoodie for hiking, travel, and long days outdoors.
The Lost Boys Merino Sun Hoodie combines natural merino wool performance with lightweight sun protection. Merino wool naturally regulates temperature, resists odor, and stays comfortable during long days on the trail or while traveling. As part of our Venture Far Series, it uses our highest quality fabrics and trims for elevated durability and performance. With four chest snaps for adjustable ventilation, UPF 30+ protection, and thumbholes for added coverage, the Lost Boys is a great option for hikers, backpackers, and anyone who prefers the feel of merino wool in a sun hoodie.
Nofry Vent Sun Hoodie: The OG Sun Hoodie Built for Maximum Airflow
If your main concern is staying cool in brutal heat, the Nofry Vent Sun Hoodie is the one to grab. It is the most breathable option in the KETL lineup and was built specifically for high output activities in hot weather.
The defining feature is the four snap buttons on the chest. When temperatures climb or you are pushing hard on a climb, you can pop the snaps open to dump heat and increase airflow. When the sun is blazing or the wind picks up, snap it back up for full coverage. It is a simple feature that makes a big difference during long days outside.
The fabric itself is what really sets the Nofry Vent apart. The ultra lightweight grid knit fabric weighs just 79gsm and allows air to move freely through the material. On the body it feels almost weightless and never sticky or clingy, even when you are sweating during a hard effort.
Despite being incredibly light, the fabric still provides reliable UPF 30+ sun protection. That means you can spend hours in direct sun without constantly reapplying sunscreen on your arms and shoulders.
The Nofry Vent also dries extremely fast and packs down small, making it easy to bring along for travel or multi day adventures. Whether you are rinsing it in a sink while traveling or sweating through a hot trail run, it dries quickly and is ready to go again.
Best For
Trail running, mountain biking, hiking, backpacking, fishing, travel, and any hot weather adventure where maximum breathability matters.
Key Features
• Four snap chest buttons for adjustable ventilation
• Ultra lightweight 79gsm grid knit fabric
• UPF 30+ plus sun protection
• Thumbholes for added hand coverage
• HeiQ Mint odor control treatment

Nofry Standard Sun Hoodie: Lightweight Sun Protection in a Clean Minimal Design
The Nofry Standard Sun Hoodie takes the same ultra lightweight fabric used in the Vent version and simplifies the design for a clean, minimal feel. If you want the lightest possible sun protection without extra hardware or features, this is the most streamlined option in the lineup.
It uses the same featherweight 79gsm grid knit fabric that allows air to move freely through the material while still delivering reliable UPF 30+ sun protection. The fabric feels soft, stretchy, and almost weightless on the body, making it easy to wear all day whether you are hiking, traveling, or just spending time outside.
The biggest difference from the Vent model is the simplified front design. Instead of chest snaps, the Nofry Standard keeps the front clean and minimal for a smoother fit and easier layering under packs or other gear.
A single snap on the hood helps keep it in place during windy conditions or just when you want the hood extra secure. It is a small detail that makes a big difference when the wind picks up or the sun is intense.
Like the rest of the Nofry lineup, the fabric dries extremely fast and packs down incredibly small. That makes it an easy piece to bring along for travel, backpacking trips, or any adventure where space and weight matter.
Best For
Hiking, trail running, travel, backpacking, fishing, and everyday warm weather adventures where you want lightweight sun protection with a clean minimalist design.
Key Features
• Featherweight 79gsm breathable grid knit fabric
• UPF 30+ plus sun protection
• Clean snap free front design for minimal bulk
• Single hood snap for secure coverage in wind
• Discreet thumbholes for added hand protection
• HeiQ Mint odor control treatment
• Fast drying and highly packable

Lost Boys Merino Sun Hoodie: Natural Comfort for Adventure Travel
The Lost Boys Merino Sun Hoodie takes a different approach to sun protection by using a premium merino wool blend instead of an ultralight synthetic fabric. If you prefer the natural feel of merino and want a hoodie that performs across a wide range of conditions, this is the most versatile option in the lineup.
Merino wool is known for its ability to regulate temperature, keeping you comfortable in both warm and cool conditions. It breathes well when the day heats up and adds just enough warmth when temperatures drop. That makes the Lost Boys a great layer for everything from early morning hikes to cool evenings around camp.
One of the biggest advantages of merino is its natural odor resistance. Unlike many synthetic fabrics, merino can be worn for multiple days without developing that classic sweaty gear smell. For travel, backpacking, or long trips where you are packing light, that is a huge advantage.
The merino blend used in the Lost Boys combines 45% merino wool with Tencel and nylon for added durability and softness. The result is a fabric that feels soft and smooth against the skin while still standing up to hard use on the trail.
A fitted hood and thumbholes provide extra sun coverage and help keep sleeves in place while moving or layering. Flatlock seams reduce chafing under packs, making it comfortable for long days of hiking or travel.
Best For
Travel, backpacking, trail running, hiking, and everyday wear where comfort, versatility, and natural odor resistance matter most.
Key Features
• Premium merino wool blend for natural performance
• Temperature regulating and breathable in varying conditions
• Naturally odor resistant for multi day wear
• UPF 30+ sun protection
• Fitted hood for additional coverage
• Thumbholes for added hand protection
• Flatlock seams for chafe free comfort under packs

Sun Hoodie FAQ's
If you are still deciding which sun hoodie is right for you, here are answers to some of the most common questions about sun protection, fabric performance, and choosing the right hoodie for your adventures.
What is the difference between the Nofry Vent and Nofry Standard Sun Hoodie?
Both hoodies use the same featherweight 79gsm breathable fabric with UPF 30 plus sun protection. The main difference is ventilation and design. The Nofry Vent includes four snap buttons on the chest that allow additional airflow, while the Nofry Standard removes the chest snaps for a cleaner and more minimal design.
What is the best sun hoodie for hot weather?
The Nofry Vent Sun Hoodie is the best option for extremely hot conditions and high output activities. It features ultra breathable 79gsm fabric and four snap chest buttons that allow you to open the hoodie for additional airflow when temperatures rise.
Is a merino wool sun hoodie good for hot weather?
Yes. Merino wool naturally regulates temperature and breathes well in warm conditions. The Lost Boys Merino Sun Hoodie uses a merino blend that helps keep you comfortable across a wide range of temperatures while also resisting odor during long days outside.
Are KETL sun hoodies independently tested for UPF?
We don’t pull our UPF ratings out of thin air. Our NoFry fabrics are tested to AATCC UPF standards to verify their sun protection performance. Results can vary slightly by colorway, but every tested color meets at least a UPF 30 rating. The Lost Boys Merino Sun Hoodie was also independently tested to Australian UPF standards to confirm its sun protection.
Which sun hoodie is best for travel?
The Lost Boys Merino Sun Hoodie is a great option for travel because merino wool naturally resists odor and can be worn for multiple days without washing. It also packs easily and works well across different climates and activities.
Do sun hoodies replace sunscreen?
Sun hoodies provide UPF protection for covered areas like your arms, shoulders, neck, and back. Many people prefer wearing a sun hoodie to reduce the need for sunscreen on those areas, though sunscreen may still be useful for exposed skin such as your face and hands.
Why are sun hoodies popular for hiking and trail running?
Sun hoodies provide lightweight sun protection while remaining breathable and comfortable during high output activities. They protect your skin from sun exposure without needing constant sunscreen application and help regulate temperature during long days outdoors.
Are sun hoodies cooler than t-shirts?
In many cases, yes. Sun hoodies are designed with lightweight breathable fabrics that allow airflow while protecting your skin from direct sunlight. Because the fabric blocks the sun, your skin often stays cooler than it would in a standard t shirt where the sun is directly hitting your arms and shoulders.
Why do sun hoodies have thumbholes?
Thumbholes help keep the sleeves in place while you are moving and provide extra coverage for the backs of your hands. This helps prevent sun exposure during long days hiking, running, or biking while also making layering easier under jackets or packs.
