# Spring and Summer Bestsellers | Ice Silk Sporty Casual Trousers | The Ceiling of Breathable Black Technology + Drape
## 🔥 Core Selling Points That Grab Attention
### ✅ 'Breathable' Ice Silk Black Technology
• Made of 'Ice Silk Generation 2' fabric with 72% nylon and 28% spandex, the fiber diameter is only 13μm (25μm for regular ice silk). The air permeability measured is up to 6000g/m²/24h. Sweat evaporates completely within 5 minutes after getting wet.
• Added with Swiss organic aloe vera extract, it cools down the skin by 3 - 5°C upon contact. It keeps you cool even when sitting for a long time and prevents the pants from sticking to your legs during outdoor sports.
### ✅ 'Unrestricted' Three-Dimensional Cutting
• **Tight Waist Design**: A 3cm-wide high-elastic Lycra waistband distributes pressure evenly. It doesn't squeeze the belly even when sitting for a long time and fits waist circumferences from 86 - 122cm.
• **Straight Leg + Micro Flare Cuffs**: The pant length is 106cm (including 12cm cuffs). It naturally flares outward at an angle of 5° from the knees. When walking, the pant legs drape in a streamlined shape, making you look stylish as you move.
• **Arc-Shaped Buttock Patchwork**: Solves the problem of wrinkles in traditional straight-leg pants when sitting for a long time, making it more comfortable to wear dynamically.
### ✅ 'All-in-One' Functional Design
• **Double-Layer Composite Structure**: The outer layer is ice silk, and the inner layer is a honeycomb breathable mesh fabric. It combines sun protection (UPF40+) and moisture-wicking and quick-drying functions.
• **Cuff Magic Stickers**: Adjustable tightness (fits ankle circumferences from 18 - 28cm). When rolled up, they form a double-layer ribbed cuff, which can be lined with fleece in winter.
• **Hidden Magnetic Pocket on the Back Waist**: Compatible with iPhone 14 - 15 series and mainstream action cameras, and items can be easily taken out and put in.
### ✅ 'High-Value' Versatile Look
• The side seams of the trousers use laser engraving technology, revealing faint geometric patterns. They are delicate up close and simple from afar.
## 🎨 Design Detail Analysis
### 1. Fabric Innovation
• **Ice Silk Technology**: Through the interweaving of special-shaped fibers to form micro-channels, sweat is directed along the fiber grooves. It dries in 30 minutes in a 35°C constant temperature environment (tested).
• **UV Resistance Treatment**: Titanium dioxide nanoparticles are added, obtaining UPF40+ sun protection certification, effectively blocking 90% of ultraviolet rays.
• **Antibacterial and Deodorizing**: Silver ion antibacterial fibers are built in, with a bacteriostatic rate of 99%, meeting maternal and child safety standards.
### 2. Human Engineering Optimization
• **Three-Dimensional Cutting**:
◦ **Thigh Circumference**: 68cm (58cm for regular models), accommodating thigh fat.
◦ **Crotch Depth**: Increased by 3cm, preventing tightness when sitting for a long time.
◦ **Ankle Design**: Slightly tightened by 2cm at the ankles to prevent the pant legs from sliding up.
• **Dynamic Elasticity**:
◦ **Pant Legs**: Adopting a 'fishbone' elastic structure, the lateral stretching range reaches 200%, with no restrictions when squatting deeply.
◦ **Waist**: 6 adjustable buttons are built in the waist to precisely control the tightness.
### 3. Black Tech Accessories
• **Smart Temperature Control**: A flexible body temperature sensor is built in the waistband. When the temperature is higher than 28°C, it automatically releases microcapsules of mint fragrance.
• **Detachable Trousers Tabs**: Magnetic design, which can be replaced with reflective warning strips (for night cycling safety) or breathable mesh linings.
