TETON SportsSleeping-Bags TETON Sports Tracker 5 Lightweight Mummy Sleeping Bag

No suelo hacer evaluaciones del producto porque lo que podria escribir ya lo dijo alguien mas. Sin embargo en esta ocasion es muy importante describirles mi experiencia. Este sleeping bag NO CUMPLE con el rango de temperaturas que señala, cuidado si lo quieres usar en montaña y con el rango de temperatura que señala. No soy una persona frioleta, pero para nada, lo use en montaña, a 4000 msnm, clima templado-humedo, la noche rondó entre los 0°C y los 2°C, ademas de estar usando 3 capas de ropa y dentro del sleeping, el frio que se sentia era increible, se filtra el frio por todos lados, el gorro es diminuto y no cabe la cabeza de nadie y no la cubre, por lo que el frio en la cabeza es inevitable; si se compacta, si es ligero, pero DEFINITIVAMENTE NO es para ese rango de temperaturas, es para verano, en el jardin de tu casa a no menos de 15°C o maximo 10°C, no gasten su dinero en este sleeping, si quiere uno que los protega del frio, vale mas la pena invertirle unos pesos mas y buscarse otro. Cabe hacer mencio que es el 2 producto de esta marca que reseño muy mal, no recomendaria ni el sleeping bag ni la marca. Escribo esto y me acuerdo del frio que me hizo pasar su sleeping por confiar... NO LO COMPREN!

NOT comfortable at 20F/-7C, but usable down to around freezing. Best at 40F/5C and above.You will NOT be comfortable at 20F/-7C with this sleeping bag, in fact you'd be far too cold to sleep. However, with thermal underwear, warm socks, a beanie (or head covering of some sort), a quality sleeping pad, and inside of a 4-season tent, I've used this sleeping bag in sub-zero temperatures without any real issues. That being said, anything below freezing is uncomfortable, even with the above mentioned gear. Just remember not to open it once you settle in for the night, or you'll lose a lot of heat...In terms of comfort (which highly depends on the individual), I'd say it's "acceptable" down to around 32F/0C (while wearing the aforementioned cold weather gear), and warm or "comfortable" down to around 40F/5C (with the mentioned gear). The 20F/-7C rating is likely the "survivable" temperature, at which you would be very uncomfortable and likely unable to sleep due to the cold, but not die from hypothermia. I've also used it in warmer temperatures by simply reducing what I wear while sleeping, and leaving the bag unzipped.Overall it's a quality sleeping bag, light weight, and offers much better size/warmth performance of any sleeping bag anywhere near the price. I've used mine for a number of years now and recently bought two more for friends, as it is better than anything found in German stores for anywhere near the price.Highly recommended for backpackers/trekkers who don't plan to sleep in temperatures much colder than 40F/5C (unless you have additional quality cold weather gear). A compression sack is necessary to further reduce the size; my medium sea-to-summit compression sack holds my sleeping bag, inflatable pillow, thermal underwear, beanie, gloves, warm socks, and a few other soft/compressible items, yet is still smaller than the sleeping bag is without a compression sack). As for a compression sack, I recommend Sea to Summit, as I've had mine for years and never had any issues.

Cumple con lo esperado, cada detalle es cuidado, su construcción impide que el cierre se atore con la misma tela, lo cual resultaba un problema en otros sleepings que he tenido. Muy caliente y la sensación de la tela interna es muy cómoda. La cubierta para la cabeza se puede cerrar casi en su totalidad para evitar escape de calor o a los insectos.

This sleeping bag is well made and packs up very well for backpacking with a compression bag (not included). I tried this in -2 degree Celsius and my feet were a little cold. A second pair of socks would have done the trick. I think this sleeping bag is perfect for any temperature above freezing. The only drawback was the sleeping bag was narrow for a guy my size. I am about 5’9” and just over 200 lbs. The length was great, but the width felt a little constructive. I would still recommend this bag.

Froze my ass off at +7 celsius despite rated for negative. Being "mummy-like" you're not able to move to generate warmth. Only reason I'm giving 3 stars is compact form factor and being light and easy to carry. Perhaps would function better if paired with a sleeping mat or mattress. I would not say it is comfortable for what it is rated for. For reference my use was during camping at Algonquin park in Canada in earlyish September.
