Astrolabio Complete Ski Junior JU9L B33 Blue Black 9-10 Years

Astrolabio Complete Ski Junior JU9L B33: Total Protection for Young Skiers

The Astrolabio JU9L B33 blue-black ski suit for 9-10 year-olds is a waterproof jacket + trousers set designed to provide total protection from snow, wind, and cold in the mountains. With a certified waterproof rating of 10,000 mm and 120 g/m² thermal insulation, it keeps children dry and warm during entire days on the slopes.

Certified Waterproof and Protection

• 10,000 mm Water Column: technical fabric that withstands wet snow and heavy rain for 6-8 consecutive hours, ideal for alpine skiing days with variable conditions
• Heat-sealed Seams: heat-sealed tape on all critical seams (shoulders, sides, crotch) that prevents water infiltration even under heavy snow
• 5,000 g/m²/24h Breathability: water vapor evacuation that reduces internal sweating by 50% compared to non-breathable jackets, preventing post-exertion cooling
• DWR (Durable Water Repellent) Treatment: water-repellent finish that causes water and snow to slide off the surface, keeping the fabric dry and light

Smart Thermal Insulation

The 120 g/m² synthetic insulation strategically distributed on the jacket (120g body, 80g sleeves) and trousers (60g) ensures warmth without bulk. Effective in temperatures -10°C / +5°C with a thermal base layer underneath. Synthetic insulation retains thermal properties even when wet, unlike down which loses effectiveness with moisture.

Jacket Features

• Adjustable detachable hood: head and neck protection with elastic adjustments, removable for use on mild days
• Internal snow gaiter: elastic waist that seals against snow entry from below during falls
• Adjustable cuffs with velcro: tight closure over gloves to prevent snow and cold air entry
• Waterproof zip pockets: 2 external + 1 internal for ski pass, snacks, phone protected from moisture
• Front zip with wind flap: double protection against cold air infiltration

Trouser Features

• Integrated snow gaiters: internal elastic that fits into the ski boot, preventing snow entry during skiing
• Adjustable elastic suspenders: keep trousers in place without constricting, adaptable to growth
• Anti-abrasion reinforcements: reinforced fabric on knees and ankles that resists rubbing with ski boots and falls on icy snow
• Side zips: openings for quick ventilation when the temperature rises or activity intensifies

Who It Is Suitable For

This suit is perfect for 9-10 year-olds who ski regularly (5-15 days/season) on alpine slopes. Ideal for ski school, white weeks, mountain weekends. Suitable for temperatures -10°C / +5°C with a thermal base layer (shirt + thermal leggings). Excellent for beginner-intermediate skiers who spend entire days on the slopes (8:30 am - 4:30 pm) with outdoor lunch breaks.

When NOT to Choose It

Avoid this suit if you are looking for maximum lightness for junior ski mountaineering (prefer softshell), if the child only skis 1-2 days/year (opt for rental), or if temperatures are consistently above +10°C (risk of overheating). Not suitable for extreme freeride or advanced off-piste skiing (requires 20,000 mm+ waterproof rating).

Differences vs. Competitors

Compared to CMP junior ski suit, the Astrolabio JU9L B33 offers superior waterproofing (10,000 mm vs. 8,000 mm CMP). Against Colmar children's ski suit, it provides more generous padding (120g vs. 100g) for greater warmth. Vs. Decathlon Wed'ze 500, it features complete heat-sealed seams (Wed'ze only partial) eliminating infiltration.

Fit and Growth

Regular fit with space for thermal layers underneath without creating bulk. Grow-with-me system: adjustable suspenders and extendable cuffs allow use for 2 consecutive seasons (9-10 years + 11-12 years). Sleeve and leg length adjustable via internal seams.

Maintenance and Durability

Washing: machine wash 30°C delicate cycle, technical detergent for waterproof garments (no fabric softener which damages DWR). Drying: lay flat horizontally, no tumble dryer. DWR reactivation: tumble dry 20 minutes on low temperature or warm iron with a cloth every 10-15 washes. Estimated durability: 3-4 seasons (60-100 ski days) with proper maintenance.

Frequently Asked Questions

Is a thermal layer needed underneath? Yes, with temperatures below 0°C, we recommend a thermal shirt + thermal leggings for maximum comfort. The suit is an insulating shell, it does not replace a base layer.

Does it withstand wet spring snow? Yes, the 10,000 mm waterproofing and sealed seams protect against wet snow for 6-8 hours. Reactivate DWR with a tumble dryer if water no longer rolls off.

How long does the waterproof treatment last? The DWR lasts 10-15 washes, then it needs to be reactivated with heat (tumble dryer 20 min or warm iron). The fabric's waterproof rating (10,000 mm) remains unchanged for the entire life of the garment.
