Best reviews of 😉 Forclaz Trek 500, 32° Hiking Sleeping Bag 😀

This very compact, lightweight bag has a wide temperature range of use. Sleep comfortably from 32°F to 50°F (0° to 10°C) w/these 2 3/4 zippers w/double slider to manage the temp: tailored ventilation.

Our designers, who are all backpacking enthusiasts, designed this sleeping bag to sleep comfortably at temperatures of 32°F/0°C or above.

Usage temperature:

All our sleeping bags display the temperature rating and limit temperature, tested by an independent laboratory (AITEX), in accordance with the European standard NF ISO 23537 – 2017.
The “comfort temperature” is the lower comfort limit at which a user in relaxed position is in overall thermal balance and is neither hot nor cold (determined for an average woman in normal conditions of use). Choose your sleeping bag according to this criterion.

What are the limit temperatures for usage?

Limit temperature: temperature limit at which the user of the sleeping bag in huddled-up position is generally in thermal equilibrium and is neither cold nor hot (determined for a standard man under normal conditions of use). We recommend using an insulation mattress to optimize your thermal comfort.
This sleeping bag is lined with synthetic insulation to ensure its performance even in wet conditions.

However, this is what you need to know about temperatures:

A sleeping bag does not produce heat but retains the heat produced by the body. If you are tired and cold and you slip inside a cold, damp sleeping bag, it is very likely that you will feel cold no matter how good your sleeping bag is! During the night, your thermal comfort will therefore depend not only on climatic conditions (humidity, wind, etc.) but also on your physical condition, your equipment (mattress, etc.) and your clothing (wool underwear, etc.)

For greater comfort, before getting into your sleeping bag:

Dress simply (1 layer of clothing is enough) Warm up your extremities: Use hats, gloves, socks, bed warmers, rubbing, etc.
A flask filled with hot water can be used as a foot or bed warmer (so long as there’s no chance of it opening by accident!)
Contract your muscles (70% of the energy consumed is converted into heat) but without making any movement generating a cold airstream. Use a sleeping bag liner to maximize the heat and hygiene inside your sleeping bag.

Shape:

A generous mummy shape that is wide at the shoulders and narrow at the feet to optimize thermal insulation (no heat loss) and make the product more compact, while maintaining some freedom of movement.
Width at the shoulders 28.3″, height at the feet 13.4″ in size L.
25.2″/11.8″ in S, 26.8″/12.6″ in M, 29.9″/14.2″ in XL.
Ergonomic hood; Drawstring. 2 double-slider side zippers, lined with a flap (tube) in anti-cold fill (thermal bridges), side openings. Easy mechanical ventilation.

Weight and dimensions:

Size S 3.2 lbs, user up to 5’3″ Bag dimensions: L 16.5″ Ø 7.7″. 12.5 liter volume.
Size M 3.4 lbs, user from 5’3″ to 5’7″ tall. Bag dim.: L 16.5″ Ø 8.1″. 13.9 liter volume.
Size L 3.7 lbs, user from 5’7″ to 6′ tall. Bag dim.: L 16.5″ Ø 8.5″. 15.2 liter volume.
Size XL: 3.9 lbs, user from 6’1″ to 6’7″ tall. Bag dim.: L 16.5″ Ø 8.9″. Volume 16.7 L. Volume and dimensions may vary according to the compression applied to the product.

Size and thermal insulation:

The weight, volumes, and sizes may vary slightly owing to production tolerances.
Try your sleeping bag before buying it to choose the right size for your comfort. The point of a mummy-shaped sleeping bag is to optimize the insulation/weight/volume ratio. Indeed, with a bag that fits close to the body, you will have less volume to heat (saving your energy). Conversely, this type of bag can limit your freedom of movement, especially when the zippers are closed.

Compatibility (continued)

Can be twinned with all the Forclaz Trek 500 sleeping bag models.
Can be twinned with the older models in the 2017 “Ultralight” and 2018 “Light” ranges.

Eco-design

Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce the impact on the environment, we choose “bi-ton” dyeing, meaning only 1 out of every 2 threads are dyed. This dyed yarn is also dyed using mass pigmentation, using color pigments when the yarn is manufactured.

Eco-design (continued)

Polyester fill made of 70% recycled polyester fibers, thereby reducing its environmental impact.

All these eco-design choices lead to a reduction in the CO2 emissions of this sleeping bag of 16% compared to the old model.
