Consumer Contract Regulations (CCR)

What are the Consumer Contract Regulations?

Under the "Consumer Contract Regulations, you have the right to cancel an order for goods made at a distance. These rights start from the moment you place your order and ends 14 days from the day you receive your goods.

Your right to cancel

Your right to cancel an order for goods starts the moment you place your order and ends 14 days from the day you receive your goods.

This 14 day period is the time you have to decide whether to cancel, you then have a further 14 days to actually send the goods back.

Your Right to a Refund under CCR

You may get a refund within 14 days of either, the trader getting the goods back, or you providing evidence of having returned the goods (for example, a proof of postage receipt from the post office), whichever is the sooner.

A deduction can be made if the value of the goods has been reduced as a result of you handling the goods more than was necessary. The extent to which you can handle the goods is the same as it would be if you were assessing them in a shop.

Refunding the cost of delivery

The trader has to refund the basic delivery cost of getting the goods to you in the first place, so if you opted for enhanced service e.g. guaranteed next day, it only has to refund the basic cost.

Exemptions

There are some circumstances where the Consumer Contracts Regulations does not give you a right to cancel. These include CDs, DVDs or software if you've broken the seal on the wrapping, perishable items and tailor-made or personalised items. They also include goods with a seal for health protection and hygiene reasons that have been broken or tampered with, e.g. Climbing Equipment and PPE.

My goods are broken

If you feel that your item is defective/broken/faulty and it is still under warranty, please contact our Customer Support team([email protected])with as much information as possible with regards to the fault, including photos if applicable.

We want to reduce our impact on the environment as much as possible, the first step for this is reducing our waste. Therefore, please note that we will always offer a professional repair in the first instance; if the product can be repaired.

This may involve your product being sent back to our suppliers or to a professional repair company. Please note that due tovaried procedures, warranty claims and repairs can take between 2 and 4 weeks to be concluded

Sea to Summit Sentinel XP2 Tent Frosty Green

Season:AW26

Brand:Sea to Summit

Code:53602

Sea to Summit Sentinel XP2 Tent Overview

The Sea to Summit Sentinel XP2 is a freestanding 3-season backpacking tent engineered for exposed terrain, prolonged wet weather and changing mountain conditions where weather protection, ventilation control and internal comfort are equally important.

Tested in DAC wind tunnels to withstand wind speeds exceeding 80 km/h (50+ mph), the Sentinel XP2 combines strong structural stability with adaptable pitching configurations that allow the shelter to respond to changing conditions throughout a trip. The fully waterproof construction uses a 15D/30D Ultra-Sil LS rainfly with airfoil vents alongside a highly protective 25,000 mm hydrostatic head floor fabric designed for saturated ground and prolonged wet-weather use.

The XP2's steep sidewalls, increased internal volume, and generous headroom improve comfort during extended periods inside the shelter, while large mesh storage pockets, covered cross-ventilation, and flexible setup modes improve livability during multi-day trips.

Built with DAC pole architecture, self-equalising guylines and AirLift ventilation technology, the Sentinel XP2 balances reliable mountain-weather performance with practical comfort for two-person backpacking adventures.

Best for

  • Two-person backpacking
  • Wet-weather trekking
  • Mountain hiking
  • Multi-day adventures
  • Wind-exposed campsites
  • Long-distance trails
  • 3-season camping

Materials & Construction

Ultra-Sil LS Rainfly — Reduced Wet Stretch Performance

The Sentinel XP2 uses a 15D/30D sil/PEU Ultra-Sil LS rainfly designed to reduce water absorption and improve shape retention during prolonged wet-weather exposure.

Compared with standard nylon rainfly fabrics, the Ultra-Sil LS construction delivers approximately two times less stretch when wet, helping maintain a tighter, more stable pitch during rain and overnight temperature fluctuations.

Integrated airfoil vents support airflow while maintaining weather protection during windy conditions.

Waterproof Floor Construction — 25,000 mm Protection

The floor uses a 40D nylon fabric with a polycarbonate waterproof coating tested to a 25,000 mm hydrostatic head.

This high waterproof rating helps prevent ground moisture ingress during prolonged exposure to saturated campsites, persistent rain and demanding mountain conditions.

The floor construction is designed to maintain long-term waterproof reliability during extended backpacking use.

DAC Pole Architecture — Strength & Stability

The Sentinel XP2 uses DAC PF 9 mm and PF 9.5 mm aluminium pole architecture designed to balance freestanding stability with backpacking-ready packability.

The structural design improves strength in exposed weather while helping maintain efficient internal space and headroom for two occupants.

Non-PFAS Construction

The Sentinel XP2 is built using non-PFAS materials, meaning it avoids the use of per- and polyfluoroalkyl substances commonly found in traditional water-resistant textile treatments.

PFAS chemicals are valued for water resistance but remain in the environment for extremely long periods without naturally breaking down. Because of this persistence, they are commonly referred to as “forever chemicals”.

By removing PFAS from the Sentinel XP2 construction, Sea to Summit reduces the long-term environmental impact associated with these substances while still maintaining the waterproof protection, durability and weather resistance expected from a technical backpacking shelter.

Features & Technologies

Entry & Vestibule Design

The Sentinel XP2 features dual side-entry doors and two vestibules, improving accessibility, ventilation and overall campsite usability for two-person backpacking.

Separate entry points allow each occupant to enter and exit the tent independently without disturbing the other person during the night, while the twin vestibules create dedicated protected storage areas for backpacks, footwear and wet equipment. This separation improves interior organisation and helps maintain a cleaner sleeping environment during prolonged wet-weather use.

The dual-vestibule layout also improves airflow management and creates more flexible gear storage options during multi-day trekking trips.

Wind Tunnel Tested Stability

The Sentinel XP2 has been tested in DAC wind tunnels at wind speeds exceeding 80 km/h (50+ mph), demonstrating structural stability beyond what many standard 3-season backpacking tents are designed to handle.

This improves confidence when camping in exposed terrain and fast-changing mountain weather.

AirLift Ventilation System

The Sentinel XP2 uses recessed AirLift vents positioned beneath protective scoops to maintain airflow while helping shield the interior from rain ingress.

This cross-ventilation system supports condensation management during humid and wet-weather conditions.

Dual Point Self-Equalising Guylines

Self-equalising guylines distribute wind-loading forces across a broader area of the tent structure to improve stability during strong and inconsistent gusts.

This helps reduce stress concentration on individual anchor points during exposed campsite use.

Hangout Mode Shelter Configuration

The Sentinel XP2 supports Hangout Mode, allowing part of the rainfly to be elevated using trekking poles to create a sheltered outdoor cooking or seating area.

This provides additional protected living space during wet conditions without needing to remain fully inside the tent.

Dry Setup & Takedown System

The Sentinel XP2 supports fly-first pitching and takedown, helping protect the inner tent from rain exposure during setup and pack-down in wet environments.

This improves usability during prolonged poor-weather trips.

Covered Cross Ventilation

Twin recessed AirLift vents beneath protective scoops maintain airflow through the shelter even during rough weather.

This helps minimise condensation while retaining weather protection during overnight use.

Interior Space & Liveability

The Sentinel XP2 is designed to maximise interior comfort for two people during extended backpacking trips and poor-weather camping.

Steep sidewalls, increased headroom and a spacious rectangular floorplan improve usable internal volume for sleeping, organising gear and spending longer periods inside the shelter. Large mesh storage pockets help keep smaller essentials organised and accessible, while vestibule storage areas provide protected space for wet gear, boots and backpacks.

The layout balances efficient backpacking dimensions with noticeably improved liveability compared with more restrictive ultralight shelters.

  • Freestanding 3-season two-person tent
  • DAC PF 9 mm & PF 9.5 mm pole architecture
  • Wind tunnel tested to 80 km/h / 50+ mph
