Stay warm
without extra layers.

You know the feeling. Set off cold, warm up fast, then hit a descent and freeze. Thermies™ are lightweight thermal patches that stick to your clothing, giving you the warmth you need without the extra layer you'd end up carrying. Windproof, waterproof, and lined with the same heat-reflective film used in emergency space blankets, they're the layer you won't have to think about.

Pocket-sized backup.
