Product description of CMP 3T51445 convertible pants

Description summary

Conquer any adventure with CMP Zip Off 3T51445 convertible pants! These versatile kids´ trousers transform into shorts with a simple zip, perfect for changing weather. Crafted from lightweight, 4-way stretch polyester, they offer ultimate comfort, quick-drying, and UV protection. Dry Function technology keeps active kids dry, while the integrated belt and zipped pockets ensure a secure, practical fit for all-day exploration

CMP Zip Off 3T51445 Kids´ Convertible Outdoor Pants

Prepare your young explorers for any adventure with the exceptionally versatile and functional CMP Zip Off 3T51445 pants. Designed for active boys and girls who love the great outdoors, these trousers are the ultimate solution for changing weather conditions and all-season activities, from cool spring mornings to warm summer afternoons. Their innovative design ensures your child stays comfortable, protected, and ready for anything the trail throws their way. The core of their adaptability lies in their smart, detachable construction, offering two garments in one for maximum convenience.

Trousers that become shorts thanks to the zip-off system above the knee.

This keeps your kids ready and prepared for sudden changes in temperature or unpredictable weather conditions.

They are manufactured in lightweight, comfortable polyester fabric that stretches in four directions, is quick-drying and provides protection from the sun´s rays.

Dry Function technology helps speedy evaporation of sweat.

The garment is finished with an integrated belt, two side pockets and a rear pocket, all with zips.

Unmatched Versatility for All Seasons

The standout feature of the 3T51445 model is its brilliant zip-off functionality. These long pants effortlessly transform into comfortable shorts with a quick zip above the knee, making them the perfect "detachables" for dynamic days. Start the hike in the cool morning air with full-length protection, and as the sun climbs higher, convert them into shorts to stay cool and comfortable. This adaptability makes them a true all-seasons staple in any child´s outdoor wardrobe, eliminating the need to pack multiple items of clothing.

Engineered for Active Comfort and Freedom

Movement is key to adventure, and these pants are built to enhance it. Crafted from a high-performance synthetic material, they feature advanced four-way stretch technology. This allows for a complete and unrestricted range of motion, whether your child is climbing, running, or navigating tricky terrain. The fabric is also incredibly lightweight and compressible, making these pants easy to fold down compactly into a backpack without adding bulk or weight. The integrated Dry Function technology actively works to wick moisture and sweat away from the skin, promoting rapid evaporation to keep your child dry and comfortable, even during strenuous activity.

Protective and Practical by Design

Safety and practicality are paramount in children´s outdoor clothing. The CMP 3T51445 pants provide reliable UV Protection, adding a crucial layer of defense against the sun´s harmful rays during long hours spent outside. The thoughtful design includes practical features for a perfect fit and secure storage. An integrated belt allows for easy and precise waist adjustment, ensuring the pants stay securely in place on growing kids. For storing small treasures and essentials, the pants are equipped with two zipped side pockets and a zipped rear pocket, offering peace of mind that nothing will be lost along the way.

My big boy is 126cm (7 years old) and I took him the size 8 years old/128cm. It is too big. I have to roll up my lower legs. I think size 8 years is more like 10 years.
