iClimb 3M Thinsulate Mummy Sleeping Bag – 35°F Comfort, Ultralight & Packable

iClimb 3M Thinsulate Mummy Sleeping Bag: Warmth Without Bulk

When you’re chasing adventures from dawn trails to quiet evenings under the stars, you need gear that stays light yet keeps you warm. The iClimb 3M Thinsulate Insulation Mummy Sleeping Bag delivers warmth with a remarkably low profile. The synthetic 3M Thinsulate fill traps body heat while enabling moisture to escape, helping you stay comfortable on cool nights without the bulk of traditional down insulation. The featherless, eco-friendly design aligns with a practical outdoor lifestyle, and the 100% polyester construction resists moisture absorption, supporting reliable performance in damp conditions.

Where comfort meets smart engineering

• 3M Thinsulate insulation offers warmth with minimal weight, making it easier to carry on long hikes.
• Synthetic fill dries quickly and remains pliable in a range of conditions, reducing overnight stiffness.
• Water-resistant shell helps fend off light moisture while maintaining a soft feel against the skin.

Designed for real-world comfort

The bag employs a soft, durable 20D nylon fabric that remains skin-friendly yet tough enough for outdoor use. Features such as a dedicated pillow sleeve keep your head aligned for restful sleep, while the anatomically shaped 3D footbox provides a roomy, natural resting place for your feet after a big day outdoors. The double-layer construction with smooth-curved baffles minimizes cold spots and helps retain warmth evening after evening.

Three-season warmth and sensible warmth management

With a comfort temperature of 35°F (2°C) and a limit temperature of 27°F (-3°C), you’ll find a practical balance for spring, fall, and cool summer nights. A cinchable draft collar seals out drafts, and the design’s thoughtful baffles work to reduce heat loss while you move.

Portability, size, and fit for adventure

Weighing roughly 3 pounds, this bag is compact when packed to about 15.7 by 9 inches, and can be reduced further in size. An included stuff sack helps you organize your pack without adding bulk. Unpacked, the bag measures 82 inches by 32.6 inches, comfortably accommodating most people up to about 6'10".

Ease of care and long-term value

• Machine washable, with careful spot-cleaning recommended between trips, keeping upkeep simple and practical.
• Two-way YKK zippers ensure easy in-and-out, while thoughtful details like zipper guards reduce snagging.
• Internal pocket offers a secure spot for small essentials, adding day-to-day convenience.

Versatility and warranty you can rely on

From backpacking, camping, and trekking to travel and even guest sleepovers, the iClimb bag is built for a range of environments. A limited lifetime warranty on manufacturing defects provides additional peace of mind as you plan new adventures.
