Comfortable, dependable, and easy, trust Teton for the best gear for your next adventure Review: Comfortable, light weight, durable, and gets really hot quick - My friend recommended this bag to me in 2018. I love the weight, reliability, comfort, and ease of packing with the compress pack. I took mine to hike Mt. Fuji in 2018, where it got completely soaked for 4 hours as I hiked down the moutain and typhoon Jebi caught me off guard. It dried out well and went on many more adventures and counting. It's small enough to comfortably use for sleeping in a compact car on long road trips, random camping trips, survive the freezing nights of the Mojave desert, and can be spread out roughly on top of other blankets as an extra precaution against the cold. In 30°F weather, it gets too hot within an hour. I always have to open the zipper and let it breathe more. It was comfortable to as low as 20°F weather with no wind-chill when fully zipped. The thickness is nice and adds extra cushioning that helps me sleep or camp out in the most random places that I've ended up in. Bang for buck, this is the best sleeping bag I've ever got at this price point and one of my most reliable. The zipper and build quality is durable and beefy, while staying light weight. The comfort is amazing. I wish I could recommend this sleeping bag more and give it a 10 out of 5. My family members and friends loved it too and some have been buying it after trying mine. Review: Light and Cozy - Wow oh wow! I am blown away!! I received this bag yesterday and wanted to write a review of my first impression. While the bag was in its carrying sack, it was very lightweight and compact! The bright orange was very appealing and it was easy to fit in/out of the sack. I immediately hopped in and it was very soft and cozy with plenty of wiggle room to turn on my side or roll over. I still had plenty of leg room at the bottom of the bag as well. Once zipped up, I felt just like a mummy! I’ve not yet tested it outside in the cold weather, but I immediately felt warmer once I hopped in. I’m excited to test this out and will post an update once I’ve done so! I am a long distance hiker and plan on using this bag for “The Pacific Crest Trail.” Your Company has an amazing reputation and the bag is very affordable in comparison to other brands. ## Features - Nylon - Made in the USA or Imported - STEP UP YOUR COMFORT: This roomy bag provides more shoulder and leg room; Built-out footbox provides more room for your feet; Breathable and warm - STEP UP YOUR WARMTH: Lofty, lightweight, and highly compressible; Enjoy the unrivaled warmth of this water-resistant sleeping bag that you can take anywhere - STEP UP YOUR ADVENTURE: You can take this mummy sleeping bag anywhere; From backyard to backcountry, this is the bag you need to have a worry-free adventure - NEVER ROLL YOUR SLEEPING BAG AGAIN: TETON provides a great compression sack for stuffing your sleeping bag; Start at the bottom and stuff the bag in, then tighten the heavy-duty straps - Care instructions: Hand Wash ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075JD2WGZ | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #37,583 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #129 in Camping Sleeping Bags | | Brand | TETON Sports | | Brand Name | TETON Sports | | Closure Type | Zipper | | Color | Orange | | Customer Reviews | 4.5 out of 5 stars 625 Reviews | | EU Spare Part Availability Duration | 10 years | | Fabric Type | Nylon | | Fill Material Type | Synthetic | | Global Trade Identification Number | 00817354011695 | | Included Components | sleeping bag, compression sack | | Item Dimensions L x W | 84"L x 32"W | | Item Type Name | Ultralight Mummy Sleeping Bag | | Item Weight | 3.5 pounds | | Manufacturer | TETON Sports | | Manufacturer Part Number | 1169 | | Material | Polyester Ripstop | | Maximum Height Recommendation | 84 inches | | Model Number | 1169 | | Number of Items | 2 | | Number of Packs | 1 | | Occupancy | 1 Person | | Seasons | All Seasons | | Shape | Mummy | | ShellMaterial | Polyester | | Size | 84 x 32 x 17 | | Sport Type | Sports | | Thermal Resistance | 2.5 watts_per_meter_per_celsius | | UPC | 817354011695 | | Unit Count | 1 Count | | Warranty Description | Limited Lifetime Warranty | ## Product Details - **Age Range (Description):** Adult - **Brand:** TETON Sports - **Color:** Burnt Orange - **Material:** Polyester Ripstop - **Occupancy:** 1 Person - **Seasons:** All Seasons - **Shape:** Mummy - **Special Feature:** Compressible - **Sport:** Backpacking - **Temperature Rating:** +20˚F ## Images ![Altos 20F Synthetic - Image 1](https://m.media-amazon.com/images/I/51gjm7aMDkL.jpg) ![Altos 20F Synthetic - Image 2](https://m.media-amazon.com/images/I/51E5poTSO5L.jpg) ![Altos 20F Synthetic - Image 3](https://m.media-amazon.com/images/I/71UIBWT2UAL.jpg) ![Altos 20F Synthetic - Image 4](https://m.media-amazon.com/images/I/61pBIp7jq2L.jpg) ![Altos 20F Synthetic - Image 5](https://m.media-amazon.com/images/I/71dFus2sYiL.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Comfortable, light weight, durable, and gets really hot quick *by K***G on June 5, 2021* My friend recommended this bag to me in 2018.

I'll start with the negative being that warmth seeps out of this bag. Despite my best attempts at closing in the opening, without anything else to slow the temperature drop, it's going to get uncomfortable. If you move in your sleep, you'll get colder quicker. The good news is it'll keep you alive until the sun, movement, and coffee in the morning can reheat you. It is imperative that you put boiling water in a Nalgene bottle to stuff in this bag for overnight so you can get a decent night's rest. I've also had to put on toe warmers in my camp booties to keep my feet from being the reason I wake up in the night. The positive is that this is a great price for the weather rating. I look forward to using it for weather over 32F as we transition into the late spring/summer months. It has great compression and is perfectly lightweight. I stuff it in my backpack without the stuff sack as the buckles are too bulky and with a few good shoves from the top, I manage to fit a plethora of other kit in my pack. It will remain a staple in my backpack for the fall and spring seasons. ## Frequently Bought Together - TETON Sports ALTOS, 20 Degree and 0 Degree Sleeping Bag for Adults, Lightweight Warm Mummy Sleeping Bag for Camping, Hiking, Backpacking - Yuzonc Camping Sleeping Pad, Ultralight Camping Mat with Pillow Built-in Foot Pump Inflatable Sleeping Pads Compact for Camping Backpacking Hiking Traveling Tent - Hikenture Camping Pillow with Removable Cover - Ultralight Inflatable Pillow for Neck Lumbar Support - Upgrade Backpacking Pillow - Washable Travel Air Pillows for Camping, Hiking, Backpacking --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/63510312-altos-20f-synthetic](https://www.desertcart.hk/products/63510312-altos-20f-synthetic) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-11-10*
