What is the Ascent Pro 800?
This is a durable down-filled sleeping bag with a water-resistant outer to support you in challenging weather conditions. The Ascent Pro 800 is designed for regular camping, mountain trekking or alpine adventures in colder climates.
What is it made of?
Insulation: This sleeping bag uses 650 fill power, R.D.S Certified, European Duck Down for maximum loft (fluffiness) and insulation. European Duck Down is fantastic quality down - it has smaller clusters than Goose Down, slightly reducing the warmth to weight ratio without impacting the quality of the bag.
The down is treated with a Nikwax fluorocarbon-free Hydrophobic finish, which adds light water-resistance to the down itself.
Can't quite catch the lingo? Here's a quick breakdown.
Fill power - Fill power measures the warmth and efficiency of the down, alongside its ability to loft/fluff up. A rating of 650 fill power means that 1oz of this down fills 650 cubic inches of space when fully lofted.
R.D.S - The Responsible Down Standard ensures that the down is sourced from happy birds who haven't been plucked and have been well cared for.
Hydrophobic - Hydrophobic down dries out and lofts more quickly than untreated down, resisting moisture from sweat and condensation that may build up when you're catching z's in the bag. Fluorocarbon-free Hydrophobic finishes don't use harmful chemicals that cause damage to the environment, an excellent feature for more eco-conscious adventurers.
Outer fabric: The outer shell of this sleeping bag is made with 20D Pertex® Quantum Pro Ripstop, which provides sufficient coverage from harsher conditions, thanks to its soft, windproof, water-resistant properties. The durable construction of this fabric maximises the thermal efficiency of the insulation whilst helping prevent tears and snags. The material thrives in cool, damp environments due to its ultra-thin, water-resistant, fluorocarbon-free DWR coating, providing protection from light moisture alongside wind and cold.
Lining: The Ascent Pro 800 is lined with 20D Recycled Nylon, which provides a lightweight, breathable inner that still feels soft and cosy on the skin.
What are its features?
Starting with the bag's structure, a trapezoidal boxwall construction directs more warmth towards the body by forcing the down to sit in a trapezoid shape inside each baffle. This construction method is technically enhanced to optimise the loft and warmth of the down.
The outer and inner fabric have a differential cut. A differential cut means that these two fabric panels are sized differently, often depending on the bag's fill power.
Moisture management is enhanced with the Pertex® Quantum Pro neck baffle, due to the fabric's high breathability and lightweight feel. The filled neck baffle also helps to decrease heat loss when moving around in the bag by blocking cold air from entering. A 3D shaped neck collar helps you keep cosy and traps heat inside the sleeping bag.
The sleeping bag is fastened with a YKK® 3/4 length main zip on the left side, with a down-filled baffle running alongside to prevent a big cold spot at the entry. There's also a handy zippered internal stash pocket, perfect for storing gadgets like a phone or alarm clock.
A cool bonus feature that comes with the Ascent Pro 800 is that this sleeping bag's left and right hand (zip) models can zip together, perfect if you're out camping with your partner.
The Ascent Pro 800 has a wide mummy shape design and angled foot box. This allows the sleeping bag to spaciously surround the figure while preventing exposed cold gaps, providing extra wiggle room for fidgety sleepers!
Two storage bags are included with this sleeping bag. The zipped cotton sack is designed to store your sleeping bag at home and give it more breathing room. Storing the bag in a more spacious pack allows the down filling to remain lofted, helping to increase its overall performance and lifespan.
A drawcord stuffsack is also provided to compact the bag and carry it on the move with less bulk. Stuffsacks are meant to be stuffed! So do your best to cram your sleeping bag inside instead of folding the bag away. Stuffing randomly helps to prevent folds and creases in the down, which will prevent cold spots and gaps from developing.
