The Tyin MTI 3-Season Sleeping Bag from Mammut combines a super-durable Ajungilak MTI Endurance fabric construction with a capable synthetic insulation to keep you warm all night in damp and windy conditions.
Trinity construction for a peaceful night's sleep
Mammut's Trinity construction is designed to provide enhanced critical insulation in key areas of the body, preventing heat loss as much as possible. The 3D hood design utilises 4 layers of synthetic fibre for maximum warmth, whatever the weather. All in all, the Tyin MTI Sleeping Bag might not be the lightest, but this durable sleeper will stand the test of terrible weather and time - keeping you warmer for longer.
